Why are we here? It remains one of the largest unexplained mysteries of the universe, but particle physicists are gaining more confidence in a result from an atom smashing experiment that could be a step toward providing an answer.
We exist because the universe is full of matter and not the opposite, so-called antimatter. When the Big Bang occurred, equal parts of both should have been created and immediately annihilated each other, leaving nothing leftover to build the stars, planets and us.
Thankfully, it didn’t happen that way.
