The laws of physics have not always been symmetric, which may explain why you exist

The laws of physics have not always been symmetric, which may explain why there is more matter than antimatter in the universe.

University of Florida astronomers have found the first evidence of this necessary violation of symmetry at the moment of creation.

Parity violation the 1960s n that the universe does have a preference for either left- or right-handed shapes.

This is not the first time parity violation has been spotted, but it is the first evidence of parity violation that could affect the three-dimensional clustering of galaxies in of the universe.

The findings can't yet explain h Monthly nded up with the Royal Astronomical Society a University of Florida the Big Bang should have cr first equal amounts of matter and antimatter.
