James Webb Telescope Finds Galaxies Nearly as Old as the Early Universe
NASA’s James Webb Space Telescope has revealed early galaxies that appear almost as old as the universe itself. By analyzing 31 galaxies at high redshift, researchers estimated stellar ages of around 600 million years—close to the universe’s age at that epoch. One galaxy may even seem older than the universe, posing a potential challenge to t...

Dark Matter May Not Exist, Study Suggests Gravity Works Differently at Cosmic Scales
A new theoretical study suggests dark matter may not exist, proposing instead that gravity behaves differently across vast cosmic distances. By modifying how gravity weakens over scale, the research explains galaxy rotation and lensing effects without unseen particles, raising questions about long-standing cosmological models and inviting a fresh l...

CERN Experiments Confirm Early Universe Behaved Like a Near-Perfect Fluid
Physicists at CERN have directly observed fluid-like behaviour in the quark–gluon plasma that filled the early universe. Experiments at the Large Hadron Collider revealed wake-shaped ripples forming behind fast-moving quarks, similar to bow waves in liquids. These quark wakes confirm that the primordial “soup” of quarks and gluons behaved as ...

James Webb Helps Astronomers Chart the Universe’s Hidden Dark Matter
Astronomers have created the sharpest map yet of dark matter using deep observations from NASA’s James Webb Space Telescope. By analysing the gravitational distortion of hundreds of thousands of distant galaxies, the team traced invisible dark matter across a large region of the sky. The results confirm that dark matter forms the scaffolding arou...

New Dark Matter Simulation Could Change How Galaxies Are Thought to Evolve
Scientists at the Perimeter Institute have developed a new simulation code, KISS-SIDM, to study self-interacting dark matter. The tool shows how rare dark matter interactions can heat and collapse galaxy halos, potentially explaining dense galactic cores and the early formation of supermassive black holes.

Physicists Deploy Quantum Sensors to Hunt the Universe’s Missing Matter
Dark matter makes up most of the universe’s mass, yet it has never been directly detected. Scientists are now deploying ultracold quantum sensors, underground detectors and space telescopes to catch its faint signals. At Texas A&M, new silicon detectors aim to register extremely rare particle interactions, while global experiments push sensitivit...

Astronomers Discover Shockingly Hot Young Galaxy Cluster That Defies Theory
Astronomers have identified an exceptionally hot galaxy cluster forming just 1.4 billion years after the Big Bang. Observations reveal gas temperatures far exceeding theoretical limits, suggesting an unexpectedly violent early formation. The discovery challenges standard models of galaxy cluster evolution and points to intense activity from starbur...

New Research Suggests the Universe Could Be Lopsided, Raising Cosmology Questions
New research suggests the universe may be asymmetric, challenging the long-accepted Lambda-CDM model and standard cosmology principles.

Dark Matter May Interact with Cosmic Ghost Particles, Hinting at a Fundamental Breakthrough
New research suggests dark matter may interact with neutrinos, explaining why cosmic structures today are less clumpy than expected. This subtle interaction challenges the standard Lambda Cold Dark Matter model and could guide particle physics experiments. If confirmed, it would be a fundamental breakthrough, reshaping our understanding of the univ...

Quantum Haloscope Sharpens the Search for Dark Matter Axions at Higher Frequencies
Scientists using a quantum-powered haloscope have advanced the search for dark matter axions by probing higher mass ranges than before. The QUAX collaboration’s experiment, based in Italy, uses a microwave cavity and a strong magnetic field to detect faint axion signals. While no axions were found, the results help refine future dark matter searc...
