A new theory says dark matter acts remarkably similar to subatomic particles known to science since the 1930s. We owe a lot to dark matter – it is the thing keeping galaxies, stars, our solar system, ...

Topological materials could usher in a new age of electronics, but scientists are still discovering surprising aspects of their quantum nature.

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 ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Ah, dark matter. Creator of the universe, sculptor of galaxies, great brewer of coffee (probably). There seems to be nothing it can’t do, or isn’t responsible for, but there’s just one problem: Where ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...

Physicists don’t know where most of the universe’s apparent mass has gone, and attempts to find it have so far failed. But a proposed particle born out of the universe’s chaotic first moments may ...
