☆ 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. Argonne National LaboratoryI have predicted the exact range of expected frequencies of the resulting photons based on information physics.

☆ Planet-forming disk detected around star in another galaxy for the first time
▼ + stars: | 2023-11-30 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —For the first time, astronomers have glimpsed a young star outside the Milky Way galaxy that’s ringed by a dense disk where planets may form. The massive star, called HH 1177, and its rotating disk were spotted in the Large Magellanic Cloud, a neighboring dwarf galaxy that’s about 160,000 light-years away. The gas and dust accumulate in a flat disk around the star, known as an accretion disk, as a result of strong gravitational forces. The Multi Unit Spectroscopic Explorer, or MUSE instrument, on the telescope captured a jet of material releasing from the young star. To discern whether a disk was present around the star, the team needed to measure how quickly dense gas moved around the star.

But Webb has obtained even better data on galaxies a bit further along in development. The gas detected in star-forming regions - stellar nurseries - of teenage galaxies was much hotter, at about 24,000 degrees Fahrenheit (13,350 degrees Celsius), than observed in galaxies today. The galaxies were observed glowing with eight elements - hydrogen, helium, oxygen, nitrogen, sulfur, argon, nickel and silicon. Incidentally, oxygen is also the third-most abundant element in the universe (behind hydrogen and helium)," Strom said. The new study presents the first results from the CECILIA Survey that uses Webb to scrutinize the chemistry of distant galaxies.

☆ Leonid meteor shower peaks this weekend

CNN —Up next for end-of-year celestial spectaculars is the Leonid meteor shower, set to produce bright meteors with persistent trains streaking across the night sky. The moon will be 23% full on the night of the shower’s peak, according to the American Meteor Society. Leo is the meteor shower’s radiant, which is the point where the phenomenon appears to originate from, she explained. As the comet travels around the sun, it leaves a trail of rocks and dust that appears as the annual Leonid meteor shower when Earth moves through the debris while on its own orbital path. “Getting out and seeing any meteor shower for the first time is always fun,” she said.

CNN —Space is full of extreme phenomena, but the “Tasmanian devil” may be one of the weirdest and rarest cosmic events ever observed. Astronomers dubbed the celestial object the “Tasmanian devil,” and they observed it exploding repeatedly following its initial detection in September 2022. But the Tasmanian devil is revealing more questions than answers with its unexpected behavior. While LFBOTs are unusual events, the Tasmanian devil is even stranger, causing astronomers to question the processes behind the repetitive explosions. We’d never seen that, period, in astronomy.”To better understand the quick luminosity changes occurring in the Tasmanian devil, Ho and her colleagues reached out to other researchers to compare observations from multiple telescopes.

New details of the celestial feature have emerged in the colorful image, which unites the observational powers of Hubble Space Telescope in visible light and the James Webb Space Telescope in infrared light, which is invisible to the human eye. Hubble has long been used to search for faint, distant galaxies across different wavelengths of light. This cosmic effect occurs when closer objects — such as the galactic clusters — act like a magnifying glass for distant objects. The Webb and Hubble composite image includes "Mothra," a star system magnified by the galactic cluster pair as well as another unseen object. NASA/ESA/CSA/STScIThe team nicknamed the star system Mothra due to its extreme magnification and brightness.

CNN —Two powerful NASA telescopes have detected the oldest and most distant black hole ever found. “We needed Webb to find this remarkably distant galaxy and Chandra to find its supermassive black hole,” said lead study author Akos Bogdan, in a statement. Potential black hole theoryTypically, black holes located at the centers of galaxies only have about 0.1% the mass of the stars within their host galaxy. The unusual black hole could be an “Outsize Black Hole” that formed when a huge cloud of gas collapsed, as theorized in 2017 by Priyamvada Natarajan, a coauthor on both studies and the Joseph S. and Sophia S. Fruton professor of astronomy and professor of physics at Yale University in New Haven, Connecticut. “We think that this is the first detection of an ‘Outsize Black Hole’ and the best evidence yet obtained that some black holes form from massive clouds of gas,” Natarajan said.

☆ A woman is suing SharkNinja for claiming that its frying pan is made at temperatures hotter than the sun

SharkNinja says its frying pans have a stronger nonstick coating because they're made at 30,000°F. SharkNinja claims that its nonstick pans are manufactured under a maximum temperature of 30,000°F, which is almost three times hotter than the surface of the sun. The company says the super hot temperature ensures that the nonstick coating on its pans is more resistant than competitor pans made at lower temperatures. Brown purchased two 12-inch, nonstick frying pans made by SharkNinja in 2021, according to the lawsuit. As Brown's case unfolds, Mon said he's waiting to see whether SharkNinja will present evidence on additional foods they've tested.

Tracking stellar explosionsAstronomers have long believed that neutron star mergers are the celestial factories that create rare elements heavier than iron. What was unusual about this burst is that it lasted for 200 seconds, making it a long gamma-ray burst. One of the pair exploded as a supernova, leaving behind a neutron star, and then the same thing happened to the other star.

CNN —Traditional medical imaging – used to diagnose, monitor or treat certain medical conditions – has long struggled to get clear pictures of patients with dark skin, according to experts. Researchers say they have found a way to improve medical imaging, a process through which physicians can observe the inside of the body, regardless of skin tone. They found that a distortion of the photoacoustic signal that makes the imaging more difficult to read, called clutter, increased with darkness of skin. The applications of photoacoustic technology vary, but with the researchers’ new developments, it may help diagnose health issues more accurately and equitably. We know there’s no basis in the human genome for racial sub-speciation.”This study isn’t the first to find skin color biases in medical technology.

What if astronomers observe black holes that break this speed limit, recoiling at speeds greater than 63 million mph?

The university had previously conducted three preliminary inquiries into Dr. Dias’s research and decided the concerns did not warrant further scrutiny. On Tuesday, Dr. Hamlin said he was pleased that the journal had taken his concerns seriously. He said there were two additional instances of apparent data duplication in Dr. Dias’s work that he hoped would also be reviewed. One involves another Nature paper; the other is what Dr. Hamlin describes as a duplication of data in Dr. Dias’s thesis.
