Particles and the void

Another insight from Stenger.

All that exists are particles and the void. There are photons, leptons, and bosons. There may be gravitons. These particles all interact with each other at the speed of light and follow SU3 symmetry. Beyond these particles, nothing else exists. The fields that were presented in introductory physics - electromagnetic fields, gravitational fields, temperature fields - do not exist only the particle-particle interactions do. Calculus is not reality but is a pre-computer approximation of reality. Calculus helped scientists make progress on understanding reality before we had large computers that help us understand reality faster.

A high energy anti-photon (a photon moving backward in time and having negative energy) can knock an electron backwards in time (giving the electron negative energy) making it appear as a positron in a detector.
