After matter swirls round a black gap, it merely falls into it

The physics surrounding black holes are just weird. A gravitational source so powerful that not even light can escape can do some pretty strange things to normal matter. Over the decades, many theories have been put forward about what these strange things might be. And now new work from physicists at the University of Oxford has proven that Einstein's theory of gravity was correct once again.

Their work focused on a “plunging region” just outside the black hole’s radius. In this region, matter “plunges” directly into the black hole rather than orbiting it according to the more familiar laws of orbital mechanics. One of the paper's authors, Dr. Andrew Mummery, equates it to watching a river turn into a waterfall. Matter flows beautifully along a clearly defined path and then seemingly falls off a cliff.

Theoretical work has been carried out on this region for decades. The idea of ​​a crash originally came from Einstein's theory of gravity. It stated that if matter was close enough to a black hole, it would be driven into the black hole at almost the speed of light. However, no one had yet collected data and proven this theory.

Fraser celebrates the first direct image of a black hole.

However, data from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and Neutron star Interior Composition Explorer (NICER) changes this. They collected X-ray data from a relatively small black hole located in a star system about 10,000 light-years away. This data showed that matter (which at this point consists entirely of plasma) moves rapidly into the interior of the black hole once it reaches a certain threshold.

This discovery is just the first step in a long-term plan in which researchers hope to use a much larger telescope to study much larger black holes. The Africa Millimeter Telescope is a planned new ground-based telescope to begin operations in Namibia. The project, originally proposed in 2016, is slowly approaching first light and has so far received funding of 10 million euros.

With this new telescope, Oxford physicists hope to take a look at one of the supermassive black holes at the center of our galaxy. You could potentially even capture video of it spinning – or at least the matter surrounding it. This would be a first for black hole astronomy and a major technical achievement in itself.

Fraser discusses another strange aspect of black hole physics – how cold are they?

Currently, many other smaller black holes can be analyzed using data from existing telescopes such as NuSTAR and NICER, as well as other platforms. The paper also analyzed data from the International Space Station. With new tools and a better understanding of what to look for, more discoveries about black holes undoubtedly await us in the data already collected.

Jaden Rashada-Florida Gators lawsuit, what it’s worthwhile to find out about what's subsequent

Jaden Rashada, a former ESPN 300 quarterback recruit, sued the University of Florida and coach Billy Napier on Tuesday. Rashada claims he was scammed out of millions of dollars in name, image and image money.

The lawsuit alleges, among other things, that Napier promised the player's father a $1 million “partial payment” upon signing. Rashada never received the money and the boosters never fulfilled the deal, the lawsuit says.

It is the latest incident in a long history involving the player and the school. Now Rashada is the first known college athlete to sue his coach or a sponsor over a dispute over an NIL deal.

What's next for Rashada and Florida? Our reporters break it down.

How did we get here?

Rashada was ranked 31st overall in the 2023 class and had a prep career that included multiple transfers. He played his freshman high school season at Liberty High School (Brentwood, California). He then transferred to IMG Academy in Florida before returning to California to play three seasons at Pittsburg High School (Pittsburg, California). His college decision was based on two schools in Florida and two big zero numbers.

Rashada committed to the Miami Hurricanes in June 2022. The lawsuit states that Rashada had a $9.5 million NIL commitment with the Canes. But Rashada withdrew his commitment in November of this year and immediately moved to the Florida Gators and Coach Napier. He signed his national letter of intent during the signing period in December. However, he did not enroll in Florida, and his arrival in Gainesville was contingent on a four-year, $13.85 million name, image and likeness contract. When the contract fell through, Rashada asked for a release from his letter of intent.

2 relatives

The Gator Collective, an independent fundraising organization that distributed money to UF athletes at the time, was responsible for the deal. However, financial support did not materialize and the Gator Collective terminated the contract. Rashada was released from his letter of intent. He then attended Arizona State and committed to play for the Sun Devils, arriving on campus in July 2023.

Rashada started the first two games of the season for Arizona State, but an injury kept him out for most of the season. In three games, he was 44 of 82 for 485 yards, with four touchdowns and three interceptions.

Rashada entered the transfer portal on April 18 and is now moving to Georgia, where he has four years of eligibility remaining. – Tom VanHaaren

What's next for Rashada?

Shortly after Rashada entered the portal, Georgia emerged as a likely transfer destination for Rashada. He picked the Bulldogs on April 25 and captioned his Instagram announcement, “Compete with the BEST.” Instead of vying for the starting job at ASU with rising Michigan State transfer Sam Leavitt, Rashada is put in a situation where he will play behind Georgia's Carson Beck, a top Heisman Trophy contender and NFL hopeful.

Unless Beck is injured, Rashada will use the 2024 season for development purposes while also taking over a different offense under coordinator Mike Bobo in Athens.

A realistic goal would be to always be in the hunt for national titles as a Georgian team in 2025. He would have to face off against primary challenger Gunner Stockton, who is entering his third season with the Georgia program and gained valuable experience this spring. Both Stockton and incoming freshman Ryan Puglisi were ranked among ESPN's top 110 recruits in their respective classes. Georgia coach Kirby Smart wants to have four scholarship quarterbacks on his roster at any time, and the team has a 2025 commitment from ESPN 300 recruit Ryan Montgomery.

Rashada is the most decorated quarterback of the group, but he will have to adapt quickly, especially with Stockton ahead on the learning curve. – Adam Rittenberg

How did this affect Florida on the field?

The Gators signed Rashada in December 2022 with the expectation that he would compete for the starting spot with veteran Graham Mertz, who transferred from Wisconsin. Without him, the job went to Mertz, who threw for 2,903 yards last season, completing 73 percent of his passes and throwing 20 touchdown passes with three interceptions. Losing Rashada didn't help Napier from a PR perspective, as he drew the ire of the Florida fan base – especially after a 5-7 record heading into 2023.

DJ Lagway is the top QB prospect in the 2024 recruiting class. Underclassmen report

Florida had a plan for its future, however, as Napier was long committed to DJ Lagway, the highest-rated quarterback in the class of 2024. Lagway committed to Florida just weeks before Rashada signed his letter of intent, and the Gators were also in a massive battle to keep Lagway while other schools pursued him as signing day approached last December. Lagway said Clemson, USC and Texas A&M all made late pushes, but he ultimately signed with the Gators and enrolled early while going through spring football.

His decision to come to Florida was significant for Napier, as he hasn't yet found a solid footing for the third grade and desperately needed Lagway's commitment. Mertz is back for another season and is expected to be in the starting lineup. But there is a lot at stake this season, especially for Florida and Napier. With the season opener against rival Miami, Florida fans want to see immediate progress and results. If Mertz struggles, don't be surprised if the fans call for Lagway. –Andrea Adelson

Could Rashada's claims for the Gators have any consequences for the NCAA?

The NCAA alerted Florida nearly a year ago that it was investigating claims that the football program was violating recruiting rules, according to documents obtained by the Associated Press. ESPN's Mark Schlabach confirmed that the investigation is related to Rashada's recruitment.

Rashada claims in his lawsuit that Napier directly promised Rashada a $1 million payment from a booster if he signed with Florida, which would be a violation of NCAA policy. The NCAA punished Florida State and suspended one of its coaches in January for engaging in NIL offers to a prospect.

However, the NCAA sent a letter to its schools in late February saying it was pausing all open enforcement cases “involving third parties' involvement in NIL-related activities” after a federal judge in Tennessee issued a preliminary injunction , which prohibited the NCAA from enforcing some of its rules. This lawsuit was filed by the Tennessee Attorney General after the NCAA opened an investigation into the Vols' recruiting tactics.

Any other high-profile enforcement actions by the NCAA — such as a penalty for Napier or the Gators — could lead to further lawsuits while the association continues to face antitrust scrutiny, making it unlikely that any NCAA penalties could come anytime soon. — Dan Murphy

AstraZeneca needs to extend gross sales and convey new medication onto the market by 2030

The AstraZeneca logo is pictured at the 2021 World Artificial Intelligence Conference in Shanghai, China, July 7, 2021.

LONDON – Pharmaceutical company AstraZeneca said Tuesday it plans to increase its total revenue to $80 billion by 2030 – a 75% increase from $45.8 billion in 2023.

“We have great confidence in this $80 billion target because of the portfolio and the breadth and size of the portfolio that we see today,” AstraZeneca Chief Financial Officer Aradhana Sarin told CNBC's Arabile Gumede on Tuesday.

AstraZeneca will focus on its oncology, biopharmaceuticals and rare diseases businesses and expects to bring another 20 drugs to market over the next six years.

“Many of them could be worth $5 billion,” Sarin said. The company said in a statement that many of the new drugs could reach that annual sales figure in peak years.

AstraZeneca shares traded in Europe were last up 0.66% at 9:35 a.m. London time following the announcement.

AstraZeneca's plans include developing drugs to treat at least half of all potential cancers, as well as developing alternatives to classic treatments such as chemotherapy and radiation.

“It will take time to replace the entire market, but we believe we have the technology today to begin replacing,” Sarin told CNBC.

Some cancer treatments developed by AstraZeneca have already been approved by the US FDA, including the drug Enhertu, a so-called antibody-drug conjugate developed with Japanese drugmaker Daiichi Sankyo and aimed at treating breast cancer patients.

AstraZeneca has also announced acquisitions of pharmaceutical companies including Fusion Pharmaceuticals Inc., a company specializing in cancer treatment. On Monday, the company announced plans to build an antibody-drug conjugate manufacturing facility in Singapore.

“This is the new technology that will replace chemotherapy. This is very complex manufacturing, so you need an end-to-end solution, which is why we decided to make this investment in Singapore,” said Sarin. Investments have also been made at other AstraZeneca locations, she added.

“Post-Covid era”

AstraZeneca became a household name during the Covid-19 pandemic when it developed one of the first vaccines against the disease in collaboration with the University of Oxford. The drug, known as Vaxzevria, is being withdrawn from the market as demand wanes and other shots tailored to specific Covid variants emerge.

“For us, this is certainly the post-Covid era,” Sarin told CNBC. “We provided more vaccines during the Covid pandemic because, as you know, it was a public health crisis. It wasn’t really our job to be involved in Covid vaccines.”

AstraZeneca's business has historically focused on areas such as oncology and cardiovascular health, and this will remain the company's focus going forward, Sarin said. Drugs for diabetes and metabolic diseases would also play a role in the development of AstraZeneca, she indicated.

“We are also looking at some weight control medications and may also combine them with medications that help with comorbidities that many patients with weight control problems suffer from,” she said.

AstraZeneca struck a deal with Shanghai-based pharmaceutical company Eccogene last year for a weight-loss and cardiovascular metabolism drug, pushing into the weight-control drug race currently largely dominated by Novo Nordisk's Wegovy and Ozempic Eli LillyThis is Mounjaro.

However, supply shortages could mean competitors such as Pfizer and Amgen could play a larger role in the market this year.

E-Bikes sind beliebter denn je, aber wir sind noch lange nicht in einer Welt ohne Autos

Der Umzug nach Amsterdam war augenöffnend. Da ich im autozentrierten Vereinigten Königreich aufgewachsen bin und mich in London mit dem Radfahren schwergetan habe, kam es mir so vor, als sei die Begeisterung der Niederländer für das Fahrrad angeboren, etwas, das einfach aufgrund einer Eigenart des Nationalcharakters entstanden sei.

Dies erwies sich natürlich als falsch. Die Fahrradkultur der Niederlande ist nicht aus dem Nichts entstanden. Stattdessen ist es seine zentrale Bedeutung im täglichen Leben erstellt und geplant wurdeanstatt auf wundersame Weise vom Himmel zu erscheinen.

Die Postkarten und Videos verbergen auch die Tatsache, dass die Niederländer zwar führend im städtischen Radfahren sind, das aber nicht bedeutet, dass sie auf Autos verzichtet haben. Weit davon entfernt. Tatsächlich gibt es in den Niederlanden über 9 Millionen Autos. ungefähr eine pro 1,9 Personen – eine Zahl, die bis 2021 steigt.

Es ist eine seltsame Situation. Obwohl es in den letzten Jahren einen unglaublichen Aufschwung bei umweltfreundlichen Transportmitteln und Mobilität gegeben hat, ist das fahrradlastigste Land der Welt immer noch stark auf Autos angewiesen.

Das <3 der EU-Technologie

Die neuesten Gerüchte aus der EU-Tech-Szene, eine Geschichte unseres weisen Gründers Boris und fragwürdige KI-Kunst. Es liegt jede Woche kostenlos in Ihrem Posteingang. Jetzt registrieren!

Dies ist ein Grund die Europäische Erklärung zum Radfahren wurde im Frühjahr dieses Jahres unterzeichnet, um den Übergang zu einer umweltfreundlicheren Lebensweise zu erleichtern. Aber ist es genug?

Mit Der Klimawandel beschleunigt sich Ist es für Europa möglich, sich zu ändern, da der Handlungsbedarf immer dringlicher wird? Auf Autos verzichten und stattdessen auf Fahrräder umsteigen? Und wie konnte das passieren?

Was die Statistiken zu Fahrrädern vs. Autos sagen

Lassen Sie uns zunächst in die Daten eintauchen. Überraschenderweise werden in Europa mehr Fahrräder aller Art verkauft als Autos. Tatsächlich, es wird vorhergesagt dass bis 2030 mehr als doppelt so viele Fahrräder wie Autos auf dem Kontinent verkauft werden.

„Es wird erwartet, dass die Europäer bis 2030 jährlich 10 Millionen zusätzliche Fahrräder kaufen werden, satte 47 % mehr als 2019“, sagt Manuel Marsilio, General Manager von der Verband der europäischen Fahrradindustrie (CONEBI) sagt. Das bedeute, dass im Jahr 2030 rund 30 Millionen neue Fahrräder verkauft werden, also „mehr als doppelt so viele Pkw wie derzeit pro Jahr in der EU zugelassen werden“.

Es scheint also, dass Fahrräder in Europa bereits jetzt unglaublich beliebt sind. Wie Anke Schäffner, Chief Advocacy Officer bei ZIVauch bekannt als Deutsche Fahrradindustrie, erklärt: „In Deutschland gibt es tatsächlich mehr Fahrräder als Autos, was den Besitz betrifft.“

Schäffner zufolge gibt es im Land 84 Millionen Fahrräder (einschließlich E-Bikes), denen 49 Millionen Autos gegenüberstehen. Was Elektrofahrzeuge betrifft, gibt es 11 Millionen E-Bikes – fast siebenmal mehr als vor 10 Jahren – und 1,4 Millionen Elektroautos.

„Ich kann mir vorstellen, dass Deutschland damit nicht allein ist“, sagt Schäffner.

Wenn man bedenkt, dass Fahrräder verkaufen sich weltweit besser als Autos Es scheint, als ob die Dinge für die Freunde der grünen Mobilität ganz rosig aussehen – doch ganz so einfach ist es nicht. Zwar sind Fahrräder auf dem Vormarsch und in einigen europäischen Ländern gibt es mehr davon als Autos, aber sie werden wesentlich seltener genutzt als ihre benzinfressenden Gegenstücke.

Studien der Europäischen Kommission zeigen, dass trotz der Zunahme des Fahrrads das Auto immer noch das dominierende Fortbewegungsmittel auf dem Kontinent ist.

Selbst im weltberühmten Fahrradparadies und geografisch kompakten Niederlande werden fast zwei Drittel (62,2 %) der zurückgelegten Strecke mit dem Auto zurückgelegt. Es überrascht nicht, dass dieser Wert in anderen Ländern deutlich ansteigt, wobei der Wert in Slowenien 80,6 % erreicht.

Das ergibt ein interessantes Bild. Fahrräder erfreuen sich immer größerer Beliebtheit, sind aber im Vergleich zu Autos auf dem gesamten Kontinent immer noch schwach verbreitet.

Die Schritte zur Elektrifizierung

Während Europa immer noch auf Benzin und Autos ausgerichtet ist, ist klar, dass sich die Dinge ändern. Sowohl Elektrofahrräder als auch Autos erfreuen sich immer größerer Beliebtheit.

In Deutschland beispielsweise E-Bikes verkaufen sich besser als normale Fahrräder. Gerade diese Fahrzeuge sind ein toller Autoersatz, da sie das Reisen über längere Strecken und mit Lasten erleichtern können. Plus, Ich spreche als jemand, der mit einem E-Bike zur Arbeit fährtkommen Sie viel weniger verschwitzt zur Arbeit.

Wie ist das also passiert? Warum sind Elektrofahrzeuge auf dem Vormarsch? Laut Dr. Elizabeth Connelly – Energietechnologie- und Transportanalystin am Internationale Energieagentur (IEA) – Ein wichtiger Grund für diesen Wandel hin zur Elektrifizierung war die Durchsetzung verschiedener Vorschriften durch die EU und die europäischen Länder.

Dazu gehören „strengere CO2-Emissionsstandards für Autos und Lieferwagen, um bis 2050 eine CO2-Neutralität zu gewährleisten“, ehrgeizige CO2-Vorschriften für die meisten neuen Lkw und ReisebusseUnd die Modernisierung von Eisenbahnstrecken.

Dies hat bereits Auswirkungen auf Elektrofahrzeuge, insbesondere auf Autos. „Die Verkäufe von Elektroautos im Jahr 2023 um etwa 20 % gestiegen„, sagt Dr. Connelly, „und erreicht etwa jedes vierte verkaufte Auto.“

Das ist gut, oder? Dass wir von Benzinautos auf Elektroautos umsteigen? Auf einer Ebene, ja, Der Abschied von der Verbrennung fossiler Brennstoffe in Autos ist ein großer positiver Schrittaber es ist nicht so einfach.

Es gibt starke Argumente dafür, ganz vom Auto wegzukommen. Schäffner vom ZIV sagt, dass die Nutzung von Autos enorme Kosten verursacht, egal ob sie elektrisch sind oder nicht. Dazu können die durch ihre Nutzung und Entstehung freigesetzten Emissionen, der Platzbedarf, den sie in Städten beanspruchen, oder die „Gesundheitskosten“ gehören [incurred] aufgrund weniger körperlicher Aktivität.“

Deshalb ist es wichtig, nicht nur die Art und Weise zu ändern, wie wir unsere Fahrzeuge antreiben, sondern auch, wie wir sie nutzen. Wie Dr. Connelly feststellte, sind Elektroautos aufgrund des regulatorischen Drucks auf dem Vormarsch. Kann das Gleiche also funktionieren, um Europa fahrradzentrierter zu machen?

Hintern auf Fahrräder umstellen

Es gibt bereits Anzeichen dafür, dass eine verstärkte Regulierung diese Verkehrsverlagerung unterstützt. Marsilio von CONEBI sagt, er sei „begeistert über die … Unterzeichnung von die Europäische Erklärung zum Radfahren“, etwas, das darauf abzielt, das Radfahren in ganz Europa zu fördern und zu unterstützen.

Diese Erklärung legt eine allgemeine Politik rund um das Radfahren fest, mit Ratschlägen zum Ausbau der Infrastruktur, zur Schaffung von Platz, zur Schaffung von Fahrradnetzen und mehr. Es gibt jedoch ein großes Problem: Nichts davon ist rechtsverbindlich.

Viele der Experten, mit denen wir darüber gesprochen haben, waren der Ansicht, dass die Vorschriften weitaus strenger sein müssten, wenn das Radfahren eine Chance habe, den Autoverkehr in Europa zu überholen.

Um dieses hohe Ziel zu erreichen, hat sich Adrien Roose – CEO und Mitbegründer des Elektrofahrradunternehmens – engagiert Cowboy – glaubt, dass „ein vielschichtiger Ansatz erforderlich ist, der technische Innovation, regulatorische Unterstützung und kulturelle Veränderungen kombiniert“.

Während dies Elemente abdeckt, die in der Europäischen Erklärung zum Radfahren enthalten sind, sagt Roose, dass es weitere Richtlinien geben sollte, wie zum Beispiel „Subventionen für den Kauf von E-Bikes und die Entwicklung von Umweltzonen“ in allen Ländern.

Sowohl Roose als auch Marsilio verwiesen als Beispiel dafür auf den Erfolg von Amsterdam und Paris als Fahrradstädte. Mit Frankreich Investitionen von 2 Milliarden Euro Bei der Verbesserung der Fahrradinfrastruktur und der Subventionierung von Einkäufen sollten viele andere europäische Länder dies nachahmen, wenn Fahrräder jemals zum zentralen Transportmittel werden.

Die Hartnäckigkeit der Technik

Während Vorschriften und Investitionen eine entscheidende Rolle dabei spielen, mehr Menschen zum Radfahren zu bewegen, wird die Technologie eine große Rolle dabei spielen, das Fahrraderlebnis einfacher und attraktiver zu machen.

Ein Element, das bereits hilft – und in den kommenden Jahren noch stärker werden wird – senken selbst die Preise für E-Bikes. Mit der Verbesserung und Ausreifung der Herstellungsprozesse werden mehr Menschen Zugang zu den Fahrzeugen haben, und ihre oft unerschwinglichen Kosten werden keine so große Belastung mehr darstellen.

Auch andere Fortschritte können dazu beitragen, dass diese Maschinen nützlicher werden. Zum Beispiel ein französisches Unternehmen ESSEN gewann auf der CES 2024 eine Auszeichnung für seine Mikrobatterien. Künftig kann eine solche Technologie den Maschinen nicht nur eine größere Reichweite verleihen, sondern sie auch für den allgemeinen Anwender leichter machen. Viele E-Bikes sind derzeit unglaublich schwer, mit einem Gewicht von etwa 20 bis 25 kg.

Auch in puncto Sicherheit kann die Technologie beim Umstieg aufs Fahrrad hilfreich sein. Während Städte noch immer für Autos ausgelegt sind, besteht für Radfahrer eine größere Gefahr, was viele Menschen davon abhalten kann, ihr Fahrverhalten zu ändern.

Zum Glück gibt es Unternehmen, die sich damit auseinandersetzen. Ein solches Beispiel ist Safeware, das hat hat eine tragbare Airbag-Weste entwickelt das sich automatisch aufbläst und den Benutzer schützt, wenn er in einen Unfall verwickelt wird.

Was die Städte anbelangt, wäre eine weitere Änderung, die dieser Umstellung auf das Radfahren zugute kommen würde, mehr Ladestationen für E-Bikes sowie sichere Parkmöglichkeiten. Roose von Cowboy sagt, dass Diebstahl oft eine der „[main] Hürde für den Kauf eines E-Bikes.“ Er glaubt, dass sich Fahrradhersteller darauf einstellen müssen, was Cowboy damit getan hat Finde mein Fahrrad Technologie.

Schließlich gibt es enorme Möglichkeiten für VR, Europa beim Übergang zu einem fahrradzentrierten Kontinent zu unterstützen. Während viele von uns selbstbewusste Radfahrer sind, gibt es einen Teil der Bevölkerung, der sich bei der Nutzung der Maschinen weniger sicher ist. In diesen Fällen können Virtual-Reality-Simulationen sowie die Ausweitung von Fahrradkursen dazu beitragen, den Umgang mit Zweirädern zu verbessern.

All diese Elemente können dazu beitragen, Menschen zum Fahrradfahren zu bewegen, aber das allein wird nicht ausreichen.

Das Bedürfnis nach Negativität

Wir sind alle Gewohnheitstiere. Obwohl es Elektroautos schon seit Jahren gibt und in vielen Ländern erhebliche Subventionen erhalten, Noch immer machen sie nur rund ein Fünftel des Autoabsatzes aus.

Und das gilt nur für das Autofahren: Man muss auf eine etwas andere Art „auftanken“. Dieser Widerstand wird um das Zehnfache steigen, wenn man versucht, die Leute dazu zu bringen, ihre Gewohnheiten völlig zu ändern und aufs Fahrrad statt ins Auto zu steigen.

Deshalb kann man Einzelpersonen nicht nur ermutigen, sondern auch entmutigen.

Einige Ansätze, die Dr. Connelly von der IEA vorschlägt, umfassen den „Ausstieg aus Fahrzeugen mit Verbrennungsmotor“ und „[banning] Kurzstreckenflüge.“ Diese aggressiven Ansätze werden Einzelpersonen dazu zwingen, auf neue Art und Weise zu reisen.

Schäffner vom ZIV geht sogar noch weiter. „Die Städte sind für Autos konzipiert, nicht mehr für Menschen“, sagt sie. Die einzige Möglichkeit, dies und die Gewohnheiten der Menschen zu ändern, besteht darin, in die entgegengesetzte Richtung zu gehen.

Vor diesem Hintergrund „müssen Städte den Platz für Autos neu verteilen“, sodass Fußgänger und Fahrräder mehr Platz haben. Darüber hinaus muss es laut Schäffner auch finanzielle Nachteile geben. „Offensichtlich ist die Nutzung eines Autos immer noch zu günstig“, sagt sie. Dies soll zu höheren Steuern und Mautgebühren auf die Fahrzeuge führen. Mit anderen Worten: Der Besitz eines Autos wird kostspieliger.

Es ist wichtig zu betonen, dass dies zusammen mit positiven Maßnahmen erfolgen muss. Sie können das Fahren nicht einfach teuer und kompliziert machen, wenn Sie das Radfahren nicht gleichzeitig unglaublich günstig und komfortabel machen. Doch die Kombination dieser Faktoren könnte zu einem vollständigen kulturellen Wandel führen.

Eine umweltfreundlichere, fahrradzentrierte Zukunft

Wenn wir ehrlich sind, ist es unwahrscheinlich, dass Autos jemals wirklich verschwinden werden – insbesondere in ländlichen Gebieten. Stattdessen muss das Ziel darin bestehen, von einer autozentrierten Welt hin zu einer fahrradzentrierten Welt zu gelangen.

Dabei geht es allerdings nicht nur um Fahrräder. Auch der öffentliche Nahverkehr und das Ridesharing müssen verbessert und die Nutzung für die Menschen vereinfacht werden, insbesondere außerhalb der städtischen Gebiete.

Auch wenn in der Öffentlichkeit ein gewisser Wunsch nach einer umweltfreundlicheren Gesellschaft besteht, wird diese Verkehrsverlagerung nicht von alleine erfolgen. Autos sind praktisch. Wenn wir dies nicht ändern können und andere Methoden wie das Radfahren kostengünstig und schmerzlos werden, wird Europa weiterhin autozentriert bleiben.

Das ist natürlich leichter gesagt als getan. Dies zu erreichen wird eine jahrzehntelange Mission sein, die enorme Investitionen und Anstrengungen erfordert. Dennoch kann es passieren. Die Niederlande zeigen, dass es möglich ist, eine Kultur zu verändern. Die Herausforderung besteht darin, die Menschen davon zu überzeugen.

Advert hominem failure within the power/local weather debate – do you agree?

By Robert Bradley Jr.

“Get off the high horse, we are all 'climate pros', you just have a different perspective on how to achieve it.” Mr Bradley interacts with anyone who questions his statements. As for your accusation that he's “making a point”? He does that every day. Catching up…” Mark Rohrbacher to Thomas Ortman (below)

Social media exchanges between free market advocates and the government on energy/climate are a great way to understand the arguments, politics, and motivations of everyone involved. Don't give up on culture, let the best ideas win. Here is a LinkedIn exchange in which I (and others) rebut a well-known ad hominem. In this case, a certain Thomas Ortman simply…disappeared.

The exchange took place with a contribution from Gavin Mooney, who describes himself as an “energy transition optimist”. “Batteries took a big leap forward in California this spring, soaking up solar energy during the day and releasing it when it’s needed in the evening,” he wrote. I have responded:

Sure, but at what cost, economically and ecologically? Resources are scarce… The government creates nothing but redistributes them from the many to the political elite.

A discussion ensued from both sides (167 comments in the last week), including this ad hominem.

Geoffrey Lakings: What needs to be understood regarding IER and its biases can be summed up in this one statement: “The Institute for Energy Research (IER) is a non-profit 'partner' organization of the American Energy Alliance that is a 501(c )(4) Grassroots organization designed to communicate IER policies to voters. The groups are led by Tom Pyle, a former lobbyist for Koch Industries.”

Mark Rohrbacher: All non-profit organizations have their benefactors, Greenpeace, Tides Foundation, Rockefeller, etc. Is it really necessary for us to pit Soros and Co. against the “Koch Brothers”?

I am so tired of “green advocates” portraying their opposition as “evil” or posting with an ulterior motive just because of the organization they belong to. It is repeated over and over again on LinkedIn and reduces the level of discourse.

Rob Bradley: Geoffrey S. Lakings Classic liberal in education and politics. Pro consumer, taxpayer, freedom and environment. What's your beef? Our several thousand supporters want to know.

The idea that wind, solar, and batteries are green and that the government should override consenting adults in its energy decisions puts the burden of proof on you.

Thomas Ortman: Thank you, Geoffrey S. Lakings. That makes perfect sense considering how Rob Bradley has been throwing hand grenades into every clean energy/clean technology discussion for years. It was clear there was a huge bias, but I didn't know the backstory.

Rob, we all have biases. My work is heavily climate pro-climate and I am not paid to promote what I believe to be true and ethical. The difference is that you are obviously well informed on the issue and yet you frequently spread misinformation/disinformation, which I find very disingenuous. It seems you enjoy throwing out an ounce of discontent and eliciting five pounds of reaction. I suppose since your position is a paid one, it would be reasonable to ask you to state your position and speak out for *something* (as opposed to your constant bushfires without offering anything constructive).
If your bias/employer is to support oil and gas – well, you must have enough integrity to say so. Then we can have an honest discussion about all the critical areas where the O&G sector can make crucial and beneficial contributions.

Mark Rohrbacher: “If your/employer bias is to support oil and gas…you must have sufficient integrity to say so.” He's not hiding anything. Get off your high horse, we are all “climate pros”, you just have a different perspective on how to achieve it. Mr. Bradley interacts with anyone who questions his statements. As for your accusation that he's “making a point”? He does that every day. Catching up…

Rob Bradley: Thomas Ortmann Incorrect. You have reversed causality. Faith first, funding last. And no, I'm not carrying the water for any company or industry, but for consumers, taxpayers, freedom and… the environment against wind, sun and batteries.

I have been a classical liberal since high school, and throughout my entrepreneurial career I challenged my bosses at Enron who promoted climate alarmism and promoted government subsidies for their wind and solar investments.

Read the emails here and see for yourself.

Rob Bradley: Thomas Ortman Their company profile includes “aim to expand this base into related areas of…clean energy products including; Solar, solid-state lighting, power, energy storage and clean technologies led to a merger with Voltabox of Texas, Inc.”

So please note that I am not taking ad hominem action against you for your bread-and-butter accusation. In fact, I never do, except in certain cases, such as the conflict of interest with Chris Tomlinson, business editor at the Houston Chronicle.

And Thomas Ortman disappeared….

Simone Biles defends her husband amid his ongoing backlash

After winning a weekend meeting, Simone Biles Let the internet know she's tired of being played with! The top athlete stood ten toes behind her husband, Jonathan Owensamid the ongoing backlash to his previous comments.

RELATED: Jonathan Owens Reveals He Had No Idea Who Simone Biles Was Before Dating

Biles dropped a strong F-bomb while addressing critics via her Instagram Story on Sunday (May 19).

“I’ll address this quickly, that joke was never a joke! You are obviously disrespectful to my relationship and my husband. So I'm going to go ahead and say this once. With all due respect, fuck off.”

Additionally, the gymnast warned that she would block anyone who continued to mention her in content dragging her husband.

“And no, I don't have to touch grass or whatever you suggest.” Simone Biles added. “@Everyone else who supports us, we love you all so much [heart hands emoticon].”

Jonathan Owens reacts to Simone's farewell message

For comparison: Jonathan Owens has been in the hot seat since December 2023. During this time, his session with “The Pivot Podcast” went viral due to several comments he made.

Firstly, he claimed that he had no idea who Simone was when they first met on the exclusive dating app Raya. He then insulted his bride in the eyes of fans when he referred to himself as “the catch” and said she drove 45 minutes to meet him for the first time.

In April, Simone shared that the ongoing backlash against her husband had “broken her down” in the past. She said she shed tears because she couldn't “clap back,” but it seems like the recent comments have pushed our good sister over the edge!

Meanwhile, Jonathan backed up his wife's reaction by reposting it on his Instagram Story with a little sauce of his own.

“If you all support, support us!!! If not, keep scrolling respectfully. Because pretending to be angry at people you don’t know from a paint can is strange behavior.”

Simone Biles wins meeting before slamming critics

As previously mentioned, Biles secured first place at the 2024 Core Hydration Gymnastics Classic on Saturday (May 18). The event took place in Hartford, Connecticut. According to Vanity Fair, it was the first time Biles competed against Olympians Suni Lee and Gabby Douglas in the same competition.

The competition was also Simone's first meet of the season. According to NBC News, she is a 37-time world and Olympic medalist.

Watch her performance below.

After her W, Simone thanked her husband Jonathan for his support in an Instagram post. The post likely sparked renewed backlash against Owens and his previous comments mentioned above.

In the post's caption, Simone Biles wrote: “With all my heart, the best supporter, I couldn’t ask for a better husband.” It included a photo of them kissing on the lips as they met, as well as a selfie.

Earlier this month, Biles and Owens celebrated their one-year wedding anniversary. As previously reported, the couple tied the knot twice – first in April at a courthouse in Texas and then again at a ceremony in Cabo San Lucas, Mexico. Last year, she told PEOPLE that she wore four different dresses during the destination wedding weekend.

LOUISVILLE, Ky. — Two of the year’s four majors are now complete, and the latest provided us with a thrilling Sunday that resulted in one player winning his first major championship while several others fell just short of the feat.

Xander Schauffele was not the only one who could take something away from Valhalla this week, though plenty others are leaving the 2024 PGA Championship with a bad taste in their mouths.

Here are this week’s winners and losers:

Winners

Over 18 holes on Sunday, Schauffele flipped the script that had dogged him throughout his career — that he couldn’t close when it mattered most.

After going 2-for-8 while holding a 54-hole lead in his PGA Tour career before the final round Sunday, Schauffele carded a 6-under 65 to finish with a 72-hole total of 21 under.

The 30-year-old won his first major championship in his 28th start and completely changed the trajectory of his career from a player who couldn’t win one of the big four to a major championship winner who is playing the best golf of his life.

He looked different under pressure on Sunday, not letting a couple of bad breaks from the tee affect him on the final two holes — and he made the biggest putt of his career on the 72nd.

“I don’t think I’d ever look at it as lacking,” Schauffele said. “I looked at it as someone that is trying really hard and needs more experience. All those close calls for me, even last week, that sort of feeling, it gets to you at some point. It just makes this even sweeter. I know it’s a major, but just winning in general, this is as sweet as it gets for me.”

Though moving to LIV Golf may have slightly removed him from the limelight, DeChambeau proved for the second straight major that the change hasn’t affected his ability to compete for the sport’s top tournaments.

After heading into Sunday at Augusta with a shot at his first green jacket and finishing tied for sixth, DeChambeau nearly added to his lone major total this week at Valhalla with an electric final round that fell just one stroke short of a playoff with Schauffele. The 2021 U.S. Open winner has now finished inside the top-10 at four of his last seven major appearances.

There’s something about DeChambeau that’s become evident during these last two majors. His quirkiness and showmanship have only increased since leaving for LIV and the fans seem to gravitate toward it. More than most golfers, DeChambeau appears to feed off that energy.

On Sunday at Valhalla, two things were clear: DeChambeau was the crowd favorite, and the way his game is shaping up, it feels like it’s only a matter of time before he wins another major.

It was nearly a year ago, after carding a 12-over 84 in the opening round of the Memorial Tournament on June 2, that Horschel broke down and admitted his confidence “is the lowest it’s been in my entire career.”

Horschel struggled mightily last season with just three top-10 finishes in 23 starts. He missed nearly as many cuts (10) as he made (13). He finished 90th in FedEx Cup points and fell to 94th in the Official World Golf Ranking.

Billy Ho is back now.

On April 21, he won the Corales Puntacana Championship (yes, it was against a lesser field). He seemed to have confidence again at Valhalla, posting a 7-under 64 on Sunday to tie for eighth at 13-under 271.

It was Horschel’s best finish in 12 starts in the PGA Championship and just his second top-10 finish in 41 major starts across his career.

MacIntyre has struggled adjusting to life in the U.S. since moving to Florida about six months ago to play regularly on the PGA Tour. A native of Scotland, MacIntyre has spent much of his career on the DP World Tour. He admitted that missing home got the best of him this season.

He missed five cuts and had just one top-10 finish in his first 10 starts.

That changed once MacIntyre put the clubs down and went home. After spending three weeks with family and friends in Scotland, he came back to the U.S. with a fresh outlook.

The European Ryder Cup team member tied for eighth at 13 under with four straight rounds under par. He didn’t have his best stuff Sunday, but he battled for a 1-under 70.

It was his best finish in a major in the U.S.

“It was a great week,” MacIntyre said. “First time I feel like I’ve really been in a major championship going into a final round. I didn’t quite have my best stuff today, but it was solid in the stuff that I’ve been working on, and more personally and almost emotionally it really worked. I stayed patient, kind of got my reward, and it’s just so pleasing to see that I can stay in the fight.”

It was quite a week for Hovland. The 2023 Tour Championship winner admitted he nearly pulled out of the tournament given how poorly he was playing. Instead, he nearly won it.

Hovland finished two strokes behind Schauffele but the result far exceeded any expectations he had coming into the week. He recently reunited with swing coach Joe Mayo, who seems to have worked some magic to get the 27-year-old playing as well as he did this week.

Hovland appeared to be ready to take over the golf world at the end of 2023, and instead he hit a wall and began searching for other ways to fix his golf swing. Now, a third-place finish at a major he nearly didn’t play could be just the tip of the iceberg.

A homecoming may have been exactly what Thomas needed. The two-time PGA Championship winner arrived at Valhalla with not only the pressure of playing at home, but also of trying to continue to turn his game around given the struggles of the last year.

Thomas had been trending in the right direction, but a T-8 finish this week — his best at a major since that 2022 PGA Championship win — may be the catalyst for his quest back to the top of the sport. Thomas not only exhibited shades of his old self, but he also gave the Louisville crowd some of its best moments, most notably, with the incredible flop shot birdie chip on the 14th hole Saturday.

“It was an unbelievable week. I’m bummed it’s over,” Thomas said Sunday. “I had so much fun. The fans were unbelievable. I played some really, really, really good golf. I played plenty well enough to win this week, and it just — yeah, I had a blast.”

Losers

The defending PGA Championship winner was blunt when he was asked to assess his performance at Valhalla this week.

“Not very good,” Koepka said. “I think it’s pretty obvious, isn’t it?”

Koepka wasn’t bad for three of the four rounds, but a 3-over 74 on Saturday knocked him out of contention for a fourth Wanamaker Trophy. He posted a 5-under 66 on Sunday to tie for 26th at 9 under over 72 holes.

It was his third straight disappointing finish at a major — he tied for 64th at the 2023 Open Championship at Royal Liverpool and for 45th at the Masters in April.

Still, Koepka believes he’s close to putting it together with the U.S. Open about a month away.

“I feel like I’m playing good,” Koepka said. “It’s just yesterday was just kind of unfortunate timing. But I felt like I’m playing all right. I missed a bunch of putts on Friday from inside like 5 feet, and then yesterday’s round was unfortunate. But other than that, I think I’m pretty close to right there.”

The defending U.S. Open champion has fewer than four weeks to turn things around before he heads to Pinehurst No. 2, where he’ll attempt to become the first back-to-back champion since Koepka in 2017-18.

Clark had a second straight disappointing finish when he missed the cut at the PGA Championship, posting 4-over 146 in the first two rounds. Last week, he tied for 47th at the Wells Fargo Championship at Quail Hollow, another event he won last year, and finished 7 over, 24 shots behind Rory McIlroy. He also missed the cut at the Masters.

After winning at Pebble Beach in early February and finishing second to Scottie Scheffler at the Arnold Palmer Invitational and The Players in March, Clark has cooled off considerably.

If DeChambeau has been the highlight of LIV Golf in the majors this year, then Rahm has been the disappointment. The two-time major winner missed the cut at this year’s PGA after finishing outside the top-40 in his Masters’ defense earlier this year.

It was more than just the results: Rahm looked out of sorts, out of rhythm and even threw a club at one point in disgust. It’s too early to say whether playing a LIV limited schedule as opposed to the normal PGA Tour routine, which Rahm excelled with in recent years, is the difference. However, it’s safe to say Rahm hasn’t been performing up to his potential in major championships.

Rahm is still one of the best players in the world, there’s no doubt about that. And he could play extremely well at Pinehurst and Royal Troon. For now, however, he clearly isn’t playing at the level we’ve come to expect of him at majors.

“​​There has been times in my career where I would say maybe I wasn’t hitting it my best but things just seemed to go your way and you carry that confidence on for a few months and got a lot of great results,” Rahm said before his first round at Valhalla. “Then if you’re not playing good, if you’re not swinging it good, then at that point you maybe need to assess do I need to change anything technically, what’s going on? It could be so many different ways to feel like you’re in a roadblock that it’s hard to exactly pinpoint one of them.”

Homa seemed to be trending in the right directions at majors after struggling mightily in them earlier in his career. After tying for 10th at The Open last season and then tying for third at the Masters, he tied for 35th at 8-under 276.

Homa posted a 3-under 68 on Thursday but couldn’t do any better over the final 54 holes.

As always, however, he’s still winning on social media. He poked fun at his friend, Scottie Scheffler, who rallied to tie for eighth Sunday after spending part of Friday morning in jail, following his arrest for a traffic incident.

“Frustrating week in KY,” Homa wrote on Instagram. “Lost to a guy who was literally in jail Friday morning. Tough look for me. The journey continues in Fort Worth next week.”

After playing in the final group at the Masters and being unable to keep with Scheffler, Morikawa was adamant that two holes cost him a chance at a green jacket. After once again finding himself in the final group at the PGA Championship and coming up short yet again, Morikawa had a different, more self-aware take on what went wrong.

“Everything,” he said after shooting even par and not making a single birdie putt until the final hole. “Look, to win a major championship, you’ve got to have your solid golf game. People talk about winning with their B-game, C-game, A-game. Felt like even though I’ve been putting the results together, it still feels like I’m playing with a C- to B-game. I wouldn’t say I’m faking it. I’m grinding and I’m putting together a score, and that’s what you can ask. But if I want to be able to close out the last two, just got to be a little bit sharper, and it’s just not there.”

Morikawa’s putter had kept him in the tournament all week long, but on Sunday it abandoned him and exposed some gaps within his game that still need to be improved if he wants to truly contend at a major again.

“These first two have been disappointing, but there can still be a positive outlook,” Morikawa said. “I’m going to have to just figure out how to be better.”

Valhalla Golf Club

There was a lot of talk about records at Valhalla this week and at the center of it all was the golf course. Not only did Valhalla surrender two 62s this week — tied for the lowest round at a major ever — but it also produced the lowest 72-hole score at any major ever.

It wasn’t strictly the fault of the course, as heavy rain caused the course to play extra soft, allowing for the best players in the world to, as Thomas said, tear it apart. But in many ways, what transpired over four rounds of play did not exactly inspire confidence that this version of Valhalla could hold up to the modern game going forward.

There’s no doubt that Valhalla failed to truly be a major championship test. Between the conditions and the way the setup often forced players into the same places and the same shots, the bunched-up leaderboard masked some of the flaws of trying to make the world’s best play their best. Don’t get me wrong: Schauffele controlled this tournament from start to finish and deserved to win. Valhalla, meanwhile, will likely be lucky to see another PGA Championship come their way any time soon.

Extra proof for the universe's gravitational wave background

The gravitational wave background was first discovered in 2016. This was announced following the release of the first data set from the European Pulsar Timing Array. A second data set has just been released and along with the Indian Pulsar Timing Array, both studies confirm the existence of the background. The latest theory seems to suggest that we are seeing the combined signal of supermassive black hole mergers.

Gravitational waves are ripples in spacetime caused by violent processes in the universe. They were predicted by Einstein in 1916 as part of his general theory of relativity. The waves are thought to be created by accelerating masses such as merging black holes, colliding neutron stars and the like. They are expected to be able to travel through space largely unhindered. Their existence was first discovered in September 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO). They are believed to have formed from a gravitational merger of two black holes 1.3 billion light-years away.

The Laser Interferometer Gravitational-Wave Observatory consists of two detectors, one in Livingston, Louisiana, and one near Hanford, Washington. The detectors use giant arms shaped like an “L” to measure tiny ripples in the fabric of the universe. Image credit: Caltech/MIT/LIGO Lab

The gravitational wave background is a random distribution of gravitational waves permeating the universe and was discovered in the European Pulsar Timing Array. The background is thought to consist of multiple superimposed gravitational waves, generated by black hole supermassive binary stars, for example. Observing the gravity wave background can provide us with a great opportunity to study the universe as a whole, similar to the cosmic background radiation. This success would not have been possible without the European Pulsar Timing Array, the Indian PTA, the North American Nanohertz Observatory and the Parkes PTA.

A Pulsar Timing Array (PTA) consists of a network of galactic pulsars that are monitored and analyzed to detect patterns in their pulse arrival times on Earth. PTAs essentially act as galaxy-sized detectors. While pulsar timing arrays have various applications, they are best known for using an array of millisecond pulsars to detect and analyze the long-wave gravitational wave background.

The paper, written by a team led by J. Antoniadis of the Institute of Astrophysics in Greece, examines the effects of the common low-frequency signal observed in the latest data from the pulsar timing array systems. The team compiles data from the four different data sets and looks for a signal that contains only high-quality data.

The conclusion was clear, further evidence of a gravity wave background. Over time and with additional pulsar timing array projects, the low-frequency gravity wave background will become more apparent. The mission now is to interpret the details of all these signals to maximize the opportunity to explore the universe in this new way.
