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, ...

Quantum Research Reveals Time May Not Always Move Forward
A new study on quantum systems suggests time might not always move forward. Researchers found that time-reversal symmetry persists in open quantum systems, challenging the traditional notion of a single directional arrow of time. The mathematical framework behind these interactions indicates that fundamental equations do not impose a distinction be...

Weak Gravitational Lensing Examines Universe’s Structure: What You Need to Know
The universe's large-scale uniformity is under scrutiny through weak gravitational lensing. Researchers are analysing data from the Euclid Space Telescope to detect potential anisotropies in cosmic expansion. If confirmed, these findings could challenge the fundamental Cosmological Principle, which assumes the universe has no preferred direction. T...

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 ...

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...

Astronomers Explore Moon as Vantage Point for Space Studies: Report
A recent symposium at the Raman Research Institute (RRI) in Bengaluru brought together over 60 scientists and researchers to discuss the Moon’s role as a vantage point for advanced astronomical studies. Organised by RRI and the U.R. Rao Satellite Centre (URSC) of ISRO, the three-day event focused on leveraging the Moon’s unique environment for ...

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...
