Frontier Supercomputer Simulates Universe with Unmatched Complexity
The Frontier supercomputer at Oak Ridge National Laboratory has conducted the most detailed universe simulation to date. Using the Hardware/Hybrid Accelerated Cosmology Code (HACC) under the U.S. Department of Energy’s Exascale Computing Project, the model incorporates dark matter, gas, and plasma interactions. With speeds reaching 1.4 exaFLOPS, ...

Euclid Space Telescope Discovers Rare Einstein Ring, Revealing Dark Matter Secrets
The Euclid space telescope has detected a rare Einstein ring around galaxy NGC 6505, located approximately 590 million light-years from Earth. This phenomenon, resulting from gravitational lensing, allows scientists to study the distribution of dark matter within the lensing galaxy. The discovery aligns with Euclid's mission to map cosmic structure...

New Cosmic Surveys Reveal Unexpected Clues About Universe’s Evolution
A new study published in the Journal of Cosmology and Astroparticle Physics reveals a potential discrepancy in the expected clumpiness of cosmic structures. Researchers from the University of Pennsylvania and Lawrence Berkeley National Laboratory analysed data from the Atacama Cosmology Telescope (ACT) and the Dark Energy Spectroscopic Instrument (...

Scientists Discover Hidden Clues to the Dark Universe in 3D Galaxy Maps
A breakthrough study has revealed new insights into the "dark universe," which consists of dark matter and dark energy. By using a novel technique called field-level inference (FLI), scientists have discovered previously hidden details in 3D galaxy maps. This method preserves the three-dimensional nature of the data, unlike traditional compression ...

Vera C. Rubin Observatory to Detect Millions of Exploding Stars
The Vera C. Rubin Observatory, set to begin its 10-year Legacy Survey of Space and Time (LSST) later this year, will track millions of Type Ia supernovae to advance our understanding of dark energy. These supernovae, resulting from white dwarf stars in binary systems, will be studied in detail to provide crucial data on the universe’s acceleratin...

Dark Matter Mass Limits Linked to Higgs Boson Interactions
Efforts to unravel dark matter's mysteries have revealed a potential mass limitation due to its interaction with the Higgs boson. A new study suggests that dark matter particles exceeding a few thousand giga-electron volts (GeV) could disrupt the Higgs boson, altering fundamental physical laws. This finding challenges the Standard Model and prompts...

Coma Cluster’s Distance Closer Than Predicted, Amplifying Hubble Tension Crisis
A new study led by Dan Scolnic and Adam Riess reveals that the Coma Cluster is 38 million light-years closer than predicted by standard cosmological models, intensifying the ongoing Hubble tension. This discrepancy, involving measurements of type Ia supernova explosions, challenges the universe's expansion rate as predicted by the Hubble–Lemaîtr...

New Study Uncovers Discrepancies in Universe’s Expansion Rate, Challenges Cosmology Models
A recent study has revealed inconsistencies in the universe's expansion rate, further challenging established cosmological models. Measurements from the Hubble Space Telescope, James Webb Space Telescope, and the Dark Energy Spectroscopic Instrument (DESI) indicate that the universe is expanding at varying speeds. This discrepancy raises critical q...

Heavy Dark Matter Could Break the Standard Model, New Research Shows
New research warns that heavy dark matter particles could interfere with the Higgs boson, leading to instability in the Standard Model of particle physics. If confirmed, this could reshape how dark matter is studied, suggesting lighter particles or new interaction mechanisms. Scientists may need to adjust experiments to focus on low-mass candidates...

Researchers Propose Evidence of Primordial Black Holes in Cosmic Objects and Earthly Materials
A study led by the University at Buffalo suggests primordial black holes (PBHs), formed in the early universe, could leave traces in both cosmic and terrestrial objects. Researchers believe PBHs, which are much smaller than stellar black holes, might leave hollow structures in celestial bodies like asteroids or moons. Additionally, passing through ...

James Webb Telescope Breaks Record with Discovery of Early Galaxies Dating 200 Million Years After Big Bang
The James Webb Space Telescope has spotted five galaxy candidates dating back to 200 million years after the Big Bang. These findings could transform our understanding of early cosmic evolution. Discovered via gravitational lensing, these galaxies, if confirmed, predate known formations and offer vital insights into the universe’s infancy. Scient...

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...

Researchers Propose New Methods to Spot Atom-Sized Primordial Black Holes Moving Across Solar System
Recent studies suggest that microscopic primordial black holes may exist within the solar system, potentially impacting planetary orbits and satellite movements. These small, early-universe black holes could also contribute to the mystery of dark matter, which makes up 85% of the universe's mass. Methods are being developed to detect their gravitat...
