https://phys.org/news/2022-01-black-hole-fuzzball-wormhole-debate.html Resolving the black hole 'fuzzball or wormhole' debate: The study attempts to put to rest the debate over Stephen Hawking's famous information paradox, the problem created by Hawking's conclusion that any data that enters a black hole can never leave. This conclusion accorded with the laws of thermodynamics, but opposed the fundamental laws of quantum mechanics. "What we found from string theory is that all the mass of a black hole is not getting sucked in to the center," said Samir Mathur, lead author of the study and professor of physics at The Ohio State University. "The black hole tr…

They're Black Holes MICHELLE STARR 2 JANUARY 2022 The image above may look like a fairly normal picture of the night sky, but what you're looking at is a lot more special than just glittering stars. Each of those white dots is an active supermassive black hole. And each of those black holes is devouring material at the heart of a galaxy millions of light-years away – that's how they could be pinpointed at all. more at link..... <<<<<<<<<<<<&lt…

An excerpt of his book with Roger Lewin, Origins Reconsidered, is forever etched in my memory, where he paints a vivid picture of a young Homo erectus dying, and slowly, through more than a million years, becoming the fossil he and Alan Walker discovered at Lake Turkana, and forever after called the Turkana boy: This image of a wait-a-bit thorn springing from what once was a boy's head I find …

Sun Halo over Sweden https://apod.nasa.gov/apod/ap211228.html "Explanation: What's happened to the Sun? Sometimes it looks like the Sun is being viewed through a giant lens. In the featured video, however, there are actually millions of tiny lenses: ice crystals. Water may freeze in the atmosphere into small, flat, six-sided, ice crystals. As these crystals flutter to the ground, much time is spent with their faces flat and parallel to the ground. An observer may find themselves in the same plane as many of the falling ice crystals near sunrise or sunset. During this alignment, each crystal can act like a miniature lens, refracting sunlight into our view and cre…

Russian scientists have discovered a new mechanism for the formation of formaldehyde in space - a compound that plays a significant role in the synthesis of organic compounds necessary for the origin of life on Earth. According to the new results, organic molecules can appear in molecular clouds in the early stages of evolution, that is, much earlier than the formation of stars in them. Molecules of water carry out the transfer of protons from oxygen atoms to a carbon atom, which catalyzes the formaldehyde synthesis reaction without the need for a large amount of energy.

Astronomers have found 70 wandering planets after having processed 20-years collected data. Wadnering planets are the planets that are located in interstellar space and are not gravitationally associated with a star or brown dwarf. Over the past 20 years, about two dozen such bodies have been discovered. The source: https://www.nature.com/articles/s41550-021-01513-x

Tests being run on the Experiential Advanced Superconducting Tokamak (EAST) trying to get a higher temperature and longer duration at the Hefei Institutes of Physical Science research centre. The device is already close to seven times warmer than the sun, but scientists are trying to upgrade the EAST…

Artificial intelligence in one of the district people's prosecutor's offices in Shanghai for the first time became the compiler of the text of the indictment, which will be presented to the criminal in court. This is reported by Economic News with reference to haggin.az According to the South China Morning Post newspaper, AI received prosecutorial skills after studying more than 17 thousand cases considered in the courts of Shanghai from 2015 to 2020. The "digital prosecutor" makes accusations with 97% accuracy, based on one thousand "characteristic features" that he identifies in court documents on specific criminal cases. "Artificial intelligence to a cer…

https://phys.org/news/2021-12-black-holes-immediately-big.html Did black holes form immediately after the Big Bang? How did supermassive black holes form? What is dark matter? In an alternative model for how the universe came to be, as compared to the 'textbook' history of the universe, a team of astronomers propose that both of these cosmic mysteries could be explained by so-called "primordial black holes." Nico Cappelluti (University of Miami), Günther Hasinger (ESA Science Director) and Priyamvada Natarajan (Yale University), suggest that black holes existed since the beginning of the universe and that these primordial black holes could themselves …

Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all galaxies—the building blocks of the universe—evolve. The work is published in a recent issue of The Astrophysical Journal. The team decided to study Leo I because of its peculiarity. Unlike most dwa…
