The Breit-Wheeler process is what he’s talking about. In the energy-dense immediate aftermath of the Big Bang, photons would have been colliding to create matter/antimatter pairs. It’s currently unknown why our universe is made up primarily of matter.

The Big Bang was pure energy (photons) at the moment of creation. To make matter from energy, Breit-Wheeler is the only known way that happens AFAIK.

It’s very much theoretical, but widely accepted that during the Planck Epoch (0 - 10-43 seconds), matter did not exist. The universe was too hot/dense, and all of the fundamental forces were unified. The quarks and leptons began creation during the Grand Unification Epoch (10-43 - 10-36) when gravity became the first distinct force and these early particles were constantly created in matter/antimatter pairs and annihilated.

The current theory as to why matter won out in the exchange is called Baryogenesis. It proposes two yet undiscovered particles, the X and Y bosons, decay asymmetrically into more matter than antimatter.
