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 ...
Our existence rests on a razor‑thin imbalance in the early cosmos. When the universe was young, matter and antimatter should ...
Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole. This proposal, which endows dark matter particles with a ...
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, ...
Scientists at Fermilab’s MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle proposed for decades to explain puzzling neutrino behavior. Their high-precision ...
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.
