After years of careful investigation, researchers working on the Micro Booster Neutrino Experiment (MicroBooNE) have determined that a ...

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 ...

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 ...

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, ...

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 ...
