Saturday Quote: The Universe doesn’t care about your valuable standard model
This slice of digital data maps celestial objects billions of light years away from the Earth (center). Among the objects are nearby bright galaxies (yellow), bright red galaxies (orange), exhaust line galaxies (blue), and quasars (green). The large-scale structure of the universe shows the most dense research area and is shown in the inset image representing less than 0.1% of…

One of the universe’s most enormous black holes in the heart of the universe
The prominent gravity lens known as the space horseshoe was discovered in 2007. New research reveals the existence of ultra-large black holes, including 36 billion solar masses. Credit: NASA/ESA/Hubble In 2007, astronomers discovered the space horseshoe, a critical lending system for a galaxy about 5.5 billion light years away. The mass of the galaxy in the foreground enlarges and distorts…

Does the universe behave the same everywhere? Weak gravitational lenses may provide the answer
Examples of how E and B modes transform images of distant galaxies. Credit: Sissa Mediaab Research published in the Journal of Cosmology and Astroparticle Physics (JCAP) demonstrates how to test the assumptions of uniformity and isotropicity of the universe, known as cosmological principles. Images collected by new observatory such as the Euclidean Space Telescope. Finding evidence of anomalies in cosmological…

Simulate the creation of particles in the magnifying universe using quantum computers
A complete circuit for measuring the number of particles created in the expanding universe. Credit: Science Report (2025). doi: 10.1038/s41598-025-87015-6. A new study published in Scientific Reports simulates particle creation in the expanding universe using an IBM quantum computer and demonstrates digital quantum simulations of quantum field theory in curved space-time (QFTC). Although attempts to create a perfect quantum theory…

Cosmic data suggests that the universe has become “more cluttered and more complicated”.
Credit: UNSPLASH/CC0 Public domain Through the history of the universe, powerful power has acted on substances, and the universe has been re -formed into a net with a more complicated structure. By the way, new research led by Joshua Kim, Matavaselil, the University of Pennsylvania, and co -researchers at the Lawrence Berkeley National Institute is about 13.8 billion years since…

The first supernova filled the early universe with water, research suggests
This artist’s impression shows CR7, a very distant galaxy discovered using ESO’s Very Large Telescope. Credit: ESO/M.Kornmesser Water is the essence of life. All living things on earth contain water within them. The Earth has an abundance of water, so life is abundant. This fundamental connection between water and life is partly due to the extraordinary properties of water, but…

Discovery of distant blazars supports rapid black hole formation in the early universe
Artist’s impression of a bright, very early active galactic nucleus discovered by Bañados and his colleagues. This has fundamental implications for the growth of black holes during the first billions of years of cosmic history. Credit: NSF/AUI/NSF NRAO/B. Saxton Astronomers have discovered a key piece of the puzzle of how supermassive black holes were able to grow so quickly in…

‘We live in a universe that’s just right for us’: study suggests testing the anthropic principle
https://commons.wikimedia.org/wiki/File:Multiverse.png. Credit: Silver Spoon The “anthropic principle” that the universe we live in is finely tuned to harbor life was first proposed by Brandon Carter in 1973. Since then, this principle has caused great debate. A paper written by Nemanja Kalopá, a physicist in the Department of Physics and Astronomy at the University of California, Davis, and Alexander Westphal, a…

The dark energy tearing apart our universe may not be what it seems, scientists say
The Dec. 14, 2023 image released by NOIRLab shows the sky above the Nicholas U. Mayall telescope at Kitt Peak National Observatory (KPNO), a program of NSF’s NOIRLab in Tucson, Arizona. This photo shows meteors from the Geminid meteor shower moving across the sky. Credit: NSF’s NOIRLab (via AP) An ancient galaxy far, far away is giving scientists yet another…

Equation of life? New model calculates the likelihood of intelligent beings existing in our universe and beyond
What the same region of the universe looks like in terms of the number of stars at different values ​​of dark energy density. Clockwise from top left: no dark energy, the same dark energy density as the universe, 30 times the dark energy density of the universe, and 10 times the dark energy density of the universe. The images are…
