"Dark matter started its life as near-massless relativistic particles, almost like light," says Robert Caldwell, a professor of physics and astronomy and the paper's senior author.

Harnessing sunlight to power the future has taken a major step forward thanks to new research on nanosized oxyhalide ...

Physicists are coming to realise that hypothetical particles called axions could explain not only dark matter, but dark energy too, and more besides. Now there is fresh impetus to detect them ...

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be.

Now scientists at the world’s largest particle collider have observed a new class of antimatter particles breaking down at a different rate than their matter counterparts.

Physicists recorded the lowest-energy neutrino event yet, using signals from the particles’ antimatter counterpart produced in a nuclear reactor.

Yes — in short, this is true for all forms of matter and energy, including dark matter and dark energy. But there are details to consider.
