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 ...

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 ...

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.
