A simple explanation of dark matter and antimatter, how they differ, how scientists study them, and why both are important to understanding the universe.

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 ...

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 image shows the predicted flux of antihelium-3 produced from dark matter (WIMPs) that annihilate producing these antinuclei. Each color represents the prediction for a different mass of dark ...

Understanding neutrinos reshapes how scientists view the birth and fate of the Universe. If CP violation in neutrinos is ...

“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 ...

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.
