One of the big problems in physics: why is there matter but no antimatter?
There are processes that generate matter and antimatter together. You need an asymmetric process that favors matter over antimatter.
We've known about one source of asymmetry since the 1960s. Some weak-force interactions act differently between matter and antimatter. That's probably the reason, but we don't fully understand it.
For the new work they've demonstrated the same effect on a different kind of particle, the baryon (a category that includes protons, though this wasn't about protons). That's a new way to gather data on the problem, and which might help understand what the real cause of the asymmetry is.
Next to all the other posts today this made me think the creator leaked some secret credentials in one of the laws of physics commits lol
Too dense for a non physicist unfortunately. Anyone care to simplify?
