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 newly found antiparticle, called antihyperhydrogen-4, could have a potential imbalance with its matter counterpart that may help scientists understand how our universe came to be. When you ...
