Mysteriously Young Galaxy Could Reveal Secrets of Early Universe
Today’s stories include Signatures of the Primordial Universe and Has the Biggest Black Hole in the Universe been Discovered? and more.
Wormhole Experiment Called Into Question--Last fall, a team of physicists announced that they had teleported a qubit through a holographic wormhole in a quantum computer. Now another group suggests that’s not quite what happened, reports Charlie Wood for Quanta.
Mysteriously Young 'Peekaboo' Galaxy Could Reveal Secrets of Early Universe--A strange discovery could provide a window into the universe’s earliest galaxies, reports Scientific American. "Peekaboo appears to have a significant lack of old stars. The new measurements suggest the dwarf galaxy may have formed billions of years after the big bang—much later than other galaxies close to ours."
The Signatures of the Primordial Universe--Suzanne Staggs, a physicist at Princeton University and founding member of the Simons Observatory, describes what cosmic microwave background (CMB) radiation can reveal about the early universe, reports The Simons Foundation.
The biggest black hole in the universe? explores Paul Sutter for Live Science. And is there a limit to how big black holes can get? "A monster, appropriately named TON 618, weighs roughly 40 billion solar masses. TON 618 has a radius of over 1,000 astronomical units (AU), which means that if the black hole was placed in the center of the solar system, by the time you reached Pluto, you would be less than 5% of the way from the center of the black hole to its edge."
Canadian Telescope Delivers Deepest-Ever Radio View of Cosmic Web--Data from the CHIME radio observatory are a milestone in the quest to discover the hidden origins of universal structure, reports Scientific American.
How tardigrades and other extremophiles adapt to alien-like environments--At least one of Earth's creatures is able to survive the vacuum of space, reports Big Think. Examples of life's impressive adaptive abilities include deep-sea marine life, fungi, and tardigrades. These bizarre creatures show that nature never fails to surprise."
Artificial Intelligence Discovers Secret Equation for ‘Weighing’ Galaxy Clusters, reports The Simons Foundation. “It’s such a simple thing; that’s the beauty of this,” says study co-author Francisco Villaescusa-Navarro, a research scientist at the Flatiron Institute’s Center for Computational Astrophysics (CCA) in New York City. “Even though it’s so simple, nobody before found this term. People have been working on this for decades, and still they were not able to find this.”
Massive asteroid to pass by Earth on weekend, reports BBC. "The object, named 2023 DZ2, was discovered a month ago. On Saturday, it will pass within 515,000km of the moon, before flying by Earth hours later. It is rare for such a huge asteroid - estimated to be between 40 and 90 meters in diameter - to come so close to the planet.
Climate Freeloaders Are Destroying the Planet--Governments are ignoring calls to stop fossil fuel expansion—despite there being little time left to avoid the worst effects of global warming, reports Wired.
Join physicist Brian Keating and Eric Weinstein in this frank discussion diving deep into philosophical and existential questions of nuclear war, UFOs, faith, belief, global conflict, and more.
