When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel scientists' assumptions about the forces that make up all of matter and space. But now, a new precision measurement has reset the balance and confirmed scientists' theories, at least for one of the universe's core building blocks.
