Rolf Landua: What happened to antimatter?

What happened to antimatter?

Particles come in pairs which is why there should be an equal amount of matter and antimatter in the universe. Yet scientists have not been able to detect any in the visible universe. Where is this missing antimatter? CERN scientist Rolf Landua returns to the seconds after the Big Bang to explain the disparity that allows humans to exist today. [Directed by Franz Palomares, narrated by Rolf Landua].

While theory says every particle has an equal antimatter twin, the observable universe contains almost none. If matter and antimatter meet, they annihilate in a flash as powerful as an atomic bomb, yet only matter remains today. After the Big Bang, nearly all matter and antimatter annihilated, but a tiny imbalance left just enough matter for stars and humans to exist. The reason for this asymmetry remains one of the deepest mysteries in modern physics.
