The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

Dark matter is one of the oldest open problems in physics. It makes up most of the matter in the universe and shapes how galaxies form and move, yet no one has ever directly detected it. Physicists ...

The phenomenology of dark matter in particle physics addresses the bridge between theoretical models of unseen matter and the experimental or observational signatures that might reveal its nature.

For decades, physicists have searched for dark matter, the invisible substance thought to make up roughly 85% of all matter in the universe. Although its gravitational influence shapes galaxies and ...

In popular science, dark matter is a hotly discussed topic. With various theories regarding its existence and interaction with regular matter, many scientists agree that these are some questions that ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

UCLA's Alvine Kamaha and her colleagues on the LUX-ZEPLIN experiment observed an event that could be interpreted as a signal from WIMPs — weakly interacting massive particles Dark matter is the ...

Sukanya Chakrabarti has been elected a Fellow of the American Physical Society, one of the most prestigious honours of the ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

Researchers suggest that dark matter might subtly color light red or blue as it passes through, revealing traces of its existence. Using a network-like model of particle connections, they argue that ...
