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...

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...

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...

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 ...

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...

Black Holes Explosions Driven by Hawking Radiation May Unveil New Physics
Primordial black holes, potentially formed shortly after the Big Bang, may be undergoing explosions across the universe, driven by Hawking radiation. Physicists believe that capturing these rare events could reveal undiscovered particles and fundamental physics. Dr. Marco Calzà and Dr. João G. Rosa from the University of Coimbra have proposed way...

Asteroid Bennu Examines Potential Fifth Force and Dark Matter Connection
Research on asteroid Bennu reveals no evidence of a potential fifth force that could explain dark matter. NASA’s OSIRIS-REx mission tracked Bennu’s orbit with exceptional accuracy, allowing scientists to examine for subtle deviations. This study provides insight into the unknown forces in the universe and suggests that further investigation of ...
