Sep. 12—In the cosmic tug-of-war between matter and antimatter, matter has the upper hand. Our universe leans more heavily on the side of matter. In a one-to-one ratio, matter and antimatter would ...

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 ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

Add Yahoo as a preferred source to see more of our stories on Google. Current theories suggest that W and Z bosons acquire mass from interactions with the Higgs scalar field, but a new study suggests ...

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.
