The recent search for antistars can be traced back to 2018, when a $1.5-billion experiment called … Read more

Physicists think inflation initially created the same amount of matter and antimatter, which annihilate each other on contact. But then something happened that tipped the scales in favor of matter, allowing everything we can see and touch to come into existence — and a … Read more
