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 ...

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.

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 ...

For various, typically historical reasons, even the best physicists claim things that sound egregious to modern observers. That doesn’t necessarily mean these ideas are completely useless—if anything, ...

“It’s not to say that neutrinos are definitely the explanation of the matter-antimatter asymmetry, but a very large class of models that can explain this asymmetry are connected to neutrinos,” says ...

A nuclear engineer reacts to an ambitious concept explored by PBS Space Time: could antimatter-powered spacecraft exist within our lifetime? This video breaks down how antimatter propulsion would work ...
