Yes — in short, this is true for all forms of matter and energy, including dark matter and dark energy. But there are some important details to consider. Usually, the part of the equation containing ...

Physicists have shown that, like everything else experiencing gravity, antimatter falls downwards when dropped. This outcome is not surprising — a difference in the gravitational behaviour of matter ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

A new theory for the origins of dark matter suggests that fast-moving, neutrino-like dark particles could have decoupled from Standard Model particles far earlier than previous theories had suggested.

In a first, CERN physicists succeeded in observing matter-antimatter imbalance in baryons, fundamental particles that make up most of the observable universe. Reading time 3 minutes All matter in our ...

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 ...
