  Dark Matter Could Be Linked to a ‘Dark Big Bang’, New Study Suggests

  New research suggests that dark matter may have originated from a "Dark Big Bang," a cosmic event distinct from the standard Big Bang. Proposed by scientists at Colgate University, the theory explores scenarios where dark matter could have been introduced into the universe up to a year after the initial Big Bang. Unlike regular matter, dark matter ...

  World's 2nd Fastest Supercomputer Simulates Universe’s Largest Evolution Model

  The Frontier supercomputer, the second fastest globally, has completed the most comprehensive universe simulation to date. Led by Argonne National Laboratory, the project used the HACC code to model cosmological hydrodynamics. By incorporating factors beyond gravity, like gas dynamics and star formation, the simulation provides a detailed understan...

  Einstein’s Theory of Relativity Passes Its Biggest Test After Observations From Dark Energy Spectroscopic Instrument

  A new study by the Dark Energy Spectroscopic Instrument (DESI) suggests dark energy might not be constant over time, potentially altering cosmological models. Conducted at the Kitt Peak National Observatory, the project’s 3-D galaxy map highlights the role of dark energy in shaping the universe’s expansion. Researchers found evidence that dark ...

  James Webb Space Telescope Finds First Evidence of Einstein Zig-Zag Phenomenon In a Distant Quasar

  Data from the James Webb Space Telescope has revealed the first-ever Einstein zig-zag, where light from quasar J1721+8842 bends through two distinct warped space-time regions. Six mirrored images of the quasar and a faint Einstein ring confirm this rare lensing effect. Scientists believe this discovery could help resolve critical issues in cosmolog...

  Study Claims Black Holes Could be Driving Universe's Expansion

  A new study proposes that black holes could hold the key to dark energy, which fuels the accelerating expansion of the universe. Using the Dark Energy Spectroscopic Instrument (DESI), astronomers observed a possible correlation between the growth of black holes and an increase in dark energy. The study's co-authors, Gregory Tarlé and Duncan Farrah...

  3 Decades Later, First Brown Dwarf Ever Found Offers A Surprise

  In 1995, astronomers confirmed the discovery for the first time of a brown dwarf, a body too small to be a star and too big to be a planet - sort of a celestial tweener. But it turns out that was not the full story.

  James Webb Space Telescope Corrects Misconceptions About Sizes of Early Galaxies

  The James Webb Space Telescope (JWST) has provided new insights into the size of early galaxies, revealing they are less massive than once believed. Previous observations suggested that these galaxies were much larger than the standard cosmological model predicted. However, by examining infrared light from these galaxies, scientists, including Dr S...
