Physicists have studied a rare molecule to look at how magnetism is distributed within a radioactive nucleus for the first time.
The rules of nature don’t, generally speaking, change. If you toss a ball in Seattle or in Tokyo, it falls the same way. Physicists call this “symmetry”, and they use symmetry as a guide to how the universe ought to behave. It’s what keeps the world consistent — if the laws of physics worked differently on Tuesdays, the universe would be chaos.
