They all have vertical symmetry. This means you can draw a mirror line down through the middle of each shape and divide it into two reflected halves. Remember vertical means from top to bottom.

However, when particles transform or decay into other particles, for example as occurs when an atomic nucleus undergoes radioactive decay, CP violation causes a crack in this mirror-like symmetry. The ...

This bold concept could address dark matter mysteries and explain cosmic symmetry gaps. In Turok’s hypothesis, right-handed neutrinos—unobserved in our universe—could exist in the mirror ...
