From the perspective of quantum field theory, every point in space is represented by a quantum oscillator; one for each elementary particle type. Higher energy oscillations represent the presence of real particles. However even the lowest possible energy oscillation – the one corresponding to the absence of particles – has some energy.

He picked up the phone and called Richard Feynman. The fateful conversation began, “Feynman, I know why all electrons have the same charge and the same mass." "Why?" asked Wheeler’s former graduate student. "Because, they are all the same electron!" Wheeler went on to describe the One-Electron Universe idea: that there exists only one electron, and that electron traverses time in both directions. It bounces in time, eventually traversing the entire past and future history of the universe in both directions, and interacting with itself countless times on each pass. In this way it fills the universe with the appearance of countless electrons. And when the electron is moving backwards in time it is a positron; the antimatter counterpart of the electron.Written and Hosted by Matt O’Dowd Produced by Rusty WardGraphics by Kurt RossAssistant Editing and Sound Design by Mike PetrowMade by Kornhaber Brown (www.kornhaberbrown.com)Comments answer by Matt:0xFFF1https://www.youtube.com/watch?v=xgdNBQCdhdA&lc=z23sjnwjrwnljxe3macdp435v2eqfl1uknp1kknjllxw03c010c Daniel Grasshttps://www.youtube.com/watch?v=xgdNBQCdhdA&lc=z230gbubioqjyn1vfacdp43azemsjdresxvjbu412tdw03c010c M Paulsonhttps://www.youtube.com/watch?v=xgdNBQCdhdA&lc=z221xpzafrikhxyjf04t1aokgiuxpnkzxeknjelcsx0jbk0h00410 Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasQuasarTambe BarsbayMax LevineMayank M.
