New Study Finds Hercules-Corona Borealis Great Wall Bigger and Nearer Than Thought
GRBs uncover a more massive and closer Hercules–Corona Borealis Great Wall, reshaping cosmic scale theories.Astronomers have found that the Hercules–Corona Borealis Great Wall—the largest known structure in the universe—is even larger and closer than previously thought. Spanning 10 billion light-years, this immense cluster of galaxies was t...

Dark Energy May Not Be Constant - How This Discovery Can Change Science
The great Russian physicist and Nobel laureate Lev Landau once remarked that "cosmologists are often in error, but never in doubt". In studying the history of the universe itself, there is always a chance that we have got it all wrong.

Did Black Hole Radiation Shape the Universe?
A study suggests that Hawking radiation, first proposed by Stephen Hawking, may have influenced the universe’s structure. According to reports, primordial black holes that existed in the early universe could have evaporated through Hawking radiation, impacting matter distribution. The research explores how these black holes might have shaped gala...

New Research Suggests Dark Energy Is Evolving, Challenging Cosmology Models
New research from the DESI project suggests that dark energy, once thought to be a constant force, may actually be changing over time. This challenges long-held cosmological models that assume a stable influence of dark energy on the universe’s expansion. By mapping 15 million galaxies, DESI’s data raises new questions about cosmic evolution. S...

ESA’s Euclid Telescope Releases First Data, Mapping 26 Million Galaxies
ESA’s Euclid telescope has released its first dataset, mapping 26 million galaxies within a week. The observations include deep-field images, a survey of 380,000 galaxies, and 500 new gravitational lens candidates. Scientists will continue tracking cosmic evolution over six years. The dataset, currently 35 terabytes, is expected to grow to 2 peta...

Atacama Telescope Reveals Most Detailed Cosmic Microwave Background Yet
New images from the decommissioned Atacama Cosmology Telescope offer the most detailed view of the cosmic microwave background. The data reveals early cosmic structures, tracks primordial gas movement, and refines estimates of the universe’s total mass. While supporting existing models, it does not resolve the Hubble tension. Researchers are now ...

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...
