A mysterious excess of far-ultraviolet light seen across the Milky Way could come from the annihilation of clumpy dark matter ...

The hero is regular matter, which is everything we can see around us. Antimatter is the mirror-image explosive twin that scientists understand well but can barely find. And dark matter is the ...

Matter and antimatter should have completely wiped each other out eons ago, leaving the Universe a very empty place. Obviously that didn't happen. Experiments at the Large Hadron Collider (LHC) may ...

Antimatter, particles with opposite charge to their matter counterparts, was theoretically predicted and later experimentally confirmed, existing naturally due to charge conservation in particle ...

An overabundance of antimatter in showers of charged particles that bombard Earth called cosmic rays could reveal the secrets of dark matter, the universe's most mysterious "stuff," a new study ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

Understanding why matter and antimatter behave differently is key to understanding why there is a universe at all. Now physicists have discovered the latest example of a subtle difference between the ...

Knotted structures once imagined by Lord Kelvin may actually have shaped the universe’s earliest moments, according to new ...

The Milky Way is glowing in ways it should not, and the usual suspects like stars, dust and black holes cannot fully account ...

Why does the Universe exist instead of having been annihilated shortly after its birth? This fundamental question in physics ...
