☆ The largest map of the cosmos hints that dark energy is changing. It could prove Einstein wrong and upend a pillar of modern physics.

New data from the largest 3-D map of our universe suggests we may be wrong about dark energy. One of the driving forces behind that evolution is also one of our age's biggest mysteries in physics: dark energy. Einstein abandoned the idea as his "greatest blunder" in the 1930s, as astrophysicist Ethan Siegal explains, but a constant dark energy would have vindicated him. "If true, it would be the first real clue we have gotten about the nature of dark energy in 25 years," Adam Riess, a Nobel laureate for his co-discovery of dark energy, told Quanta Magazine. "The idea that dark energy is varying is very natural," Paul Steinhardt, a Princeton University cosmologist, told the magazine.

Estimated to cost at least $3 billion, the project DUNE (Deep Underground Neutrino Experiment), is led by scientists at the US Department of Energy's Fermilab. AdvertisementCavern excavation at the Sanford Underground Research Facility in South Dakota began in 2017. The beam will then travel underground for 800 miles to the detectors at the South Dakota Sanford Underground Research Facility. The Sanford Underground Research Facility is located at a former gold mine.

☆ NASA says the solar eclipse cutting from Texas to Maine in April 2024 will be way cooler than any before it. Here's why.

If this sounds familiar, it's because in 2017, a 70-mile-wide band of the US saw a total solar eclipse, while many other areas saw a partial eclipse. But the total eclipse coming in April will be even cooler, excited NASA scientists told reporters at an American Geophysical Union meeting.

☆ A physicist says it's possible to determine if our universe is a giant simulation and has launched a crowdfunding campaign to fund his experiment

But another is that our universe is a computer simulation, with someone (perhaps an advanced alien species) fine-tuning the conditions. In a virtual reality, this limit would correspond to the speed limit of the processor, or the processing power limit. Similarly, virtual reality needs an observer or programmer for things to happen. AdvertisementIt is reasonable to assume that a simulated universe would contain a lot of information bits everywhere around us.

☆ A supermassive black hole is actually losing energy instead of gobbling it all up, new research shows
▼ + stars: | 2023-11-21 | by ( Sonam Sheth | ) www.businessinsider.com time to read: +2 min

Scientists have obtained the first ever proof that black holes can lose energy. They've long believed that magnetic fields could suck energy out of black holes but didn't have proof — until now. The M87 supermassive black hole is emitting energy like "million-light-year-long Jedi lightsabers," the co-author of a new study said. AdvertisementScientists have long believed that black holes, which generally swallow up everything around them, can also lose energy. Space.com noted that Albert Einstein's theory of relativity predicted that black holes can lose energy and scientists have believed since the 1970s that magnetic fields can extract energy from black holes.

☆ Right again, Einstein! Study shows how antimatter responds to gravity
▼ + stars: | 2023-09-27 | by ( Will Dunham | ) www.reuters.com time to read: +5 min

Antimatter is the enigmatic twin of ordinary matter, possessing the same mass but with an opposite electrical charge. Under current theory, the Big Bang explosion that initiated the universe should have produced equal amounts of matter and antimatter. However, antimatter can be synthesized under controlled conditions, as in the ALPHA experiment, which used antihydrogen created at CERN. "The nearly complete absence of naturally occurring antimatter is one of the great questions facing physics," Wurtele said. "No matter how pretty the theory, physics is an experimental science," Fajans said.

☆ Time appeared to move 5 times slower in the early days of the universe, scientists found

A new study found that time appeared to move five times slower in the early days of the universe. Scientists used quasars — enormously bright supermassive black holes — to arrive at their findings. The researchers used quasars — supermassive black holes that feed on gas and are among the brightest known celestial objects — to arrive at their finding. Quasars "are crucial to understanding the early universe," one astronomer said in 2018. Albert Einstein, in his general theory of relativity, predicted that we live in an expanding universe, where time was slower in its early years, and now the researchers in this study observed that.

☆ An experiment that reaches across the galaxy has 'heard' an invisible sea of ripples in space-time for the first time. It's surprisingly loud.
▼ + stars: | 2023-06-30 | by ( Morgan Mcfall-Johnsen | ) www.businessinsider.com time to read: +9 min

Those ripples are probably the distant thunder of countless collisions between supermassive black holes, throughout space and time. He predicted that the intense gravity of extremely massive objects, like black holes, warps the fabric of space-time. The NSF funded the 15-year experiment, which is called the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). Supermassive black holes are thought to exist at the center of every galaxy. Her lab runs computer models of merging supermassive black holes to predict how they behave and what signals they send out into space.

☆ A $175 check signed by Steve Jobs is up for auction—it’s 'expected to fetch $25,000' or more

But if you find one signed by Apple co-founder Steve Jobs, it might be worth extra cash. RR Auction, a Boston-based organization that sources and sells historical autographs, manuscripts and artifacts, is auctioning off a $175 check signed by Steve Jobs in July 1976. The check is expected to fetch $25,000," over 142 times its original worth, according to the company's press release. In 1974, Jobs left his role as a video game designer and reconnected with Steve Wozniak, a former high school friend. When Jobs was kicked out of Apple in 1985, he started a rival computer company called NeXT.

[1/5] High school students Konstantinos Timinis and Vladimir Baranov work on "Alnstein", a robot powered by ChatGPT, in Pascal school in Nicosia, Cyprus, March 30, 2023. REUTERS/Yiannis KourtoglouApril 4 (Reuters) - High school students and their tutors in Cyprus have developed a prototype robot powered with ChatGPT artificial intelligence technology to harness and improve teaching experiences in the classroom. Named AInstein, the squat robot created by three Pascal Schools in Cyprus stands roughly the size of a small adult and looks like a sculpted version of the Michelin Man. It is powered with ChatGPT, a chatbot developed by U.S. firm OpenAI and backed by Microsoft Corp (MSFT.O). Their experience with AInstein showed that AI is not anything to fear, project members said.

☆ The story behind Einstein's most iconic photo and how it was almost lost to history
▼ + stars: | 2023-03-25 | by ( Mike Rucker | ) www.businessinsider.com time to read: +3 min

Albert Einstein's most iconic photo of him sticking out his tongue was almost lost to history. Author Mike Rucker explains how Einstein's fun and curious nature played to his greatness. The photo was taken by Arthur Sasse, on March 14, 1951, Einstein's 72nd birthday. Einstein rarely let others get in the way of his fun. According to Walter Isaacson's biography, "Einstein: His Life and Universe," the personality traits that contributed most to Einstein's greatness were curiosity and nonconformism.
