Known physics suggests the early universe should have produced matter and antimatter in equal amounts. Nearly all of it annihilated into radiation, but roughly one extra matter particle survived for every billion pairs—and why that tiny imbalance existed remains one of physics’ deepest unsolved problems.
4+ min ago (906+ words) The measured net baryon-to-photon ratio is about 6.1 parts in ten billion. Physics can describe the required ingredients for that excess, but no confirmed mechanism made it....
