In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

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 ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...

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 ...

A NASA telescope may have detected evidence of dark matter, enabling it to be “‘seen” for the first time. Since dark matter was conceptualized nearly 100 years ago by Swiss astronomer Fritz Zwicky, ...

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 ...

For nearly a century, dark matter has been the invisible scaffolding of the universe, inferred from its gravitational pull but never directly seen. Now a cluster of independent results, from subtle ...
