Scientists made that point anew on Monday in a study that used observations of a ferocious class of black holes called quasars to demonstrate "time dilation" in the early universe, showing how time then passed only about a fifth as quickly as it does today. The observations stretch back to about 12.3 billion years ago, when the universe was roughly a tenth its present age. Quasars - among the brightest objects in the universe - were used as a "clock" in the study to measure time in the deep past. Quasars are tremendously active supermassive black holes millions to billions of times more massive than our sun, usually residing at centers of galaxies. The explosion of individual stars cannot be seen beyond a certain distance away, limiting their use in studying the early universe.

In the 1940s, physicist J. Robert Oppenheimer led a team to develop the world's first atomic bomb. His work garnered him the title "father of the atomic bomb," but he wasn't an obvious choice for its leader. He was a complicated, intelligent man known for being condescending, volatile, and impractical. He could be condescending, volatile, and impractical. Director Christopher Nolan's upcoming film about his life, called "Oppenheimer," will be released in July, with actor Cillian Murphy portraying the titular character.

Sea temperatures also broke April and May records. Global average sea surface temperatures hit 21C in late March and have remained at record levels for the time of year throughout April and May. Australia's weather agency warned that Pacific and Indian ocean sea temperatures could be 3C warmer than normal by October. Though this year's high sea temperatures are caused by a "perfect combination" of circumstances, the ecological impact could endure, she said. The Worldwide Fund for Nature, however, warned of a "worrying lack of momentum" during climate talks in Bonn this month, with little progress made on key issues like fossil fuels and finance ahead of November's COP28 climate talks in Dubai.

Neutrinos Build a Ghostly Map of the Milky Way
  + stars: | 2023-06-29 | by ( Kenneth Chang | ) www.nytimes.com   time to read: +1 min
From ghostlike particles, astrophysicists have pieced together a new map of the galaxy we live in. For now, that map of the Milky Way is blurry and incomplete. “This is the first time we’ve seen our own galaxy in anything other than light,” said Naoko Kurahashi Neilson, a professor of physics at Drexel University in Philadelphia who came up with the idea that a new view of the galaxy could be gleaned from particles known as neutrinos. Dr. Kurahashi Neilson and the more than 350 other scientists who collaborate on analyzing data from a neutrino detector at the South Pole reported their findings in a paper published on Thursday in the journal Science. “This is at last really the beginning of neutrino astronomy,” said John G. Learned, a physicist at the University of Hawaii who was not involved with the research.

CNN —For the first time, astronomers have assembled a glowing portrait of the Milky Way galaxy using cosmic “ghost particles” detected by a telescope embedded in Antarctica’s ice. Over the years, astronomers have showcased stunning images of the Milky Way through electromagnetic radiation from visible light or radio waves. These tiny, high-energy cosmic particles are often referred to as ghostly because they are extremely vaporous and can pass through any kind of matter without changing. The IceCube detector is seen under a starry night sky, with the Milky Way appearing over low auroras in the background. Cosmic rays are mostly made up of protons or atomic nuclei that have been stripped from atoms, according to NASA.

CNN —Astronomers have been able to “hear” the celestial hum of powerful gravitational waves, created by collisions between black holes, echoing across the universe for the first time. Gravitational waves, initially predicted by Albert Einstein in 1916, are ripples in space-time that were first detected in 2015. Einstein theorized that gravitational waves would stretch and compress space as they moved across the universe, affecting how radio waves travel. More than 190 scientists set out to discover the frequencies of gravitational waves as part of the North American Nanohertz Observatory for Gravitational Waves collaboration, also known as NANOGrav. Searching for a celestial choirThe newly detected gravitational waves are the most powerful ever measured.

The sun is about to enter a peak activity period, letting off space weather-causing solar flares. These solar flares aren't dangerous but have caused sporadic radio blackouts on Earth. A few powerful solar flares have already sent space weather towards our planet in recent months. NOAA/InsiderHere's what this looks like:In the time-lapse video, solar flares appear as an intense brightening of a region on the sun. How solar flares can lead to radio blackoutsDuring certain space weather events, such as solar flares, solar energetic particles travel down geomagnetic field lines in the polar regions.

There is a dedicated Instagram account on which the costume designers Molly Rogers and Danny Santiago share their finds, with 277,000 followers. Is the era of quiet luxury, so recently embraced by TikTok, already at an end? Has the physics of fashion exerted its force and produced an equal and opposite reaction to an earlier action? In many ways, the fashion in “And Just Like That …” seems to protest too much. Just as more obviously coded consumption has been around since Louis Vuitton plunked his initials on some leather back in 1896 or since Jay Gatsby started tossing his shirts.

OAKLAND, California June 27 (Reuters) - Artificial intelligence and quantum computing startup SandboxAQ on Tuesday said it has won a U.S. government contract for military cyber security in a deal that includes Microsoft (MSFT.O) and Deloitte & Touche (DLTE.UL) as subcontractors. The contract is with the Defense Information Systems Agency which provides global communications infrastructure for the Department of Defense, the Silicon Valley firm said. Earlier this year, SandboxAQ won a contract with the U.S. Air Force to research quantum navigation technology which could serve as an alternative to the Global Positioning System (GPS), which can be jammed. Quantum navigation uses sensors based on quantum physics to monitor slight local changes in the Earth's magnetic field, making navigation systems much more precise, Hidary said.

Liang took the grueling two-day exam, known as the “gaokao,” in early June alongside nearly 13 million students nationwide. Students’ exam results are their only criteria for college admission – and most candidates only get one shot, with the test happening once a year. “It may be a little difficult if I want to go to a good university this year,” he said in the video. He’d even accepted that Sichuan University might be out of reach, deciding to attend any “key university” that would accept him. Ahead of this year’s test, many students visited temples to light incense and pray for good results.

He was, he said in a memoir, “Witness to Grace” (2008), the unwanted child of an agnostic Yale University professor of religion and a mother with whom he never bonded. The two sides, called electrodes, hold charges — a negative one called an anode, and a positive one called a cathode. When a battery releases energy, positively charged ions shuttle from the anode to the cathode, creating a current. A rechargeable battery is plugged into a socket to draw electricity, forcing the ions to shuttle back to the anode, where they are stored until needed again. Materials used for the anode, cathode and electrolyte determine the quantity and speed of the ions, and thus the battery’s power.

REUTERS/Peter Nicholls/File PhotoJune 26 (Reuters) - Nobel laureate John Goodenough, a pioneer in the development of lithium-ion batteries that today power millions of electric vehicles around the globe, died on Sunday just a month short of his 101st birthday. In recent years, Goodenough and his university team had also been exploring new directions for energy storage, including a “glass” battery with solid-state electrolyte and lithium or sodium metal electrodes. Goodenough also was an early developer of lithium iron phosphate (LFP) cathodes as an alternative to nickel- and cobalt-based cathodes. After completing a bachelors in mathematics at Yale University, Goodenough received an masters and a PhD in physics from the University of Chicago.

The company also boasted of collaborations with reputable institutions that have since denied partnering with OceanGate on the submersible in question. The interior of OceanGate's Titan submersible is seen in 2018. It “hasn’t been used in a crewed submersible ever before,” he said in a video last year. OceanGate appears to have also overstated its relationships with two institutions widely respected for their innovation: Boeing and University of Washington. OceanGate had partnered with UW to create a different submersible before parting ways, the university said in a statement.

Byju's leadership is in talks with the investors to try to convince them to reverse their decision, the three sources, who declined to be named as the talks are private, told Reuters. Its rise was seen as a boost for India's startup scene as investors including General Atlantic made big bets on Byju's. Two of the sources said the investors took the decision collectively to resign from the board as they were not getting answers from Byju's founder and senior management. The departures mean Byju's board is now only made up of its founder and chief executive Byju Raveendran, his wife Divya Gokulnath, and his brother Riju Raveendran. While the investors are holding talks with Byju's, it has not yet been decided whether or not their decision to resign would change, one of the sources added.

OceanGate's Titan submersible has been missing since Sunday. OceanGate claimed that Boeing, NASA, and the University of Washington helped design the Titan. In a statement sent to Insider, Boeing said the aircraft company was not involved with the development of OceanGate's Titan. The University of Washington also released a statement saying that it wasn't involved in creating OceanGate's Titan submersible. But the collaboration resulted in a "steel-hulled vessel, named the Cyclops 1," not the design for the Titan submersible.

The explosion lasted just over a minute — considered long, like any gamma-ray burst, or GRB, that lasts more than two seconds. These violent, destructive bursts can leave behind dense remnants like neutron stars or result in the creation of black holes. Why ancient galaxies could hide star deathsDuring their search for the origin of the gamma-ray burst, astronomers used the Gemini South telescope located in Chile to observe the afterglow of the cosmic explosion. Compared with younger, more typical galaxies, ancient galaxies can have up to a million or more stars densely packed into their cores. But they had no evidence for any long gamma-ray bursts originating from ancient galaxies — until now.

Lochridge worked as an independent contractor for OceanGate in 2015, then as an employee between 2016 and 2018, according to court filings. Court filings from the company indicate there was additional testing after Lochridge’s time at OceanGate, and it’s unclear whether any of his concerns were addressed as the vessel was developed. He said more concerns were raised by contractors and employees during his time at OceanGate, and Rush became defensive and shied away from answering questions during all-staff meetings. In 2022, the legal representative updated the Virginia court on OceanGate’s expeditions in another court filing. “OceanGate decided to cancel the second mission for repairs and operational enhancements” after the vessel “sustained modest damage to its external components,” it reads.

CNN —It has been 40 years since Sally Ride became the first woman from the United States to travel into outer space. She was not open about her personal life, according to former NASA astronaut Steve Hawley, who was married to Ride from 1982 to 1987. However, the educational company she cofounded, Sally Ride Science, revealed more of her personal life in her 2012 obituary, recognizing her longtime partner, Tam O’Shaughnessy, after Ride died of pancreatic cancer. NASASherr’s book “Sally Ride: America’s First Woman in Space” was first published in 2014. A trailblazer’s legacyRide’s ambition and love of knowledge extended far beyond her role as an astronaut, Sherr noted.

"Extending the Science and Technology Agreement between the U.S. and China would only further jeopardize our research and intellectual property," said Representative Mike Gallagher, the Republican chair of a congressional select committee on China. "The administration must let this outdated agreement expire." "It is hoped that the U.S. side will expedite the internal review before the expiration of the agreement," he said. Given the state of U.S.-China ties, trying to renegotiate could derail the agreement, they said. Proponents of renewing the deal argue that without it, the U.S. would lose valuable insight into China's technical advances.

My last conversation with Cormac McCarthy, the acclaimed and elusive novelist who died last week at 89, came as unexpectedly as the first. "I thought you said Cormac McCarthy edited your book on theoretical physics?" "I got the manuscript back in the mail, and it was marked up on every page," Randall told me. By the time I interviewed Randall, Cormac was spending his days at the Santa Fe Institute, a theoretical-research institute in the piñon foothills of New Mexico. "Don't do this to yourself," McCarthy told the guy, before shutting the door in his face.
