"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." ...

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, ...

The idea that empty space is truly empty has been quietly dying for decades, but new measurements of particle spin are now forcing the issue. By tracking how tiny fragments of matter emerge with ...

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 ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

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 ...

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 ...

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 ...

An obscure theory of elementary particles proved to be key to China’s re-emergence as a scientific nation after the Cultural Revolution had stalled its development. Robert P Crease finds out more from ...

Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests. While dark matter is thought ...
