A Black Mirror Universe?

On the DESI Survey mentioned in the Neil Turok interview video above.

For every particle that is travelling forwards in time, there is an anti-particle travelling backwards in time. - Stuckelberg

"A backwards-moving electron when viewed with time moving forwards appears the same as an ordinary electron, except it’s attracted to normal electrons - we say it has positive charge. For this reason it’s called a ‘positron’. The positron is a sister to the electron, and it is an example of an ‘anti-particle’. This phenomenon is quite general. Every particle in Nature has an amplitude to move backwards in time, and therefore has an anti particle. - Richard Feynman,(1985):98 "

The Feynman-Stueckelberg interpretation, a key concept in quantum field theory, provides an alternative way to understand the behavior of antiparticles. It proposes that antiparticles, like positrons, can be seen as particles of the same kind (electrons, in this case) moving backward in time. This interpretation elegantly resolves the issue of negative energy solutions in the Dirac equation by reinterpreting them as positive energy solutions of antiparticles moving in the opposite direction of time.

Annihilation occurs at the surface of Black Holes, turning into radiation which will then travel up the horizon and escape when the Black Hole evaporates.
