Quantum gravity

›
It is best to approach quantum gravity from concrete examples, just as we did with QED. Our analysis of vacuum polarization in QED was fruit...

Unruh radiation and a time mirror

›
UPDATE: the concept of a time mirror is wrong. See our post: http://meta-phys-thoughts.blogspot.com/2018/10/path-integrals-schrodingers-cat...

We have solved the mystery of renormalization/regularization

›
UPDATE: See our post on October 13, 2018 on the Huygens principle. It gives a natural cutoff scale for all virtual loops in Feynman diagrams...

How to renormalize gravity, Hawking radiation saved, GUT?

›
Our previous post showed that regularization is just a method to remove singularities from the wave function in spacetime. Gravity has b...

The vacuum atom, non-perturbative QED, and superluminal electrons

›
In the previous blog post we uncovered the very interesting aspect of the vacuum polarization loop. It is like a stationary state of timespa...

Classical analogue of a virtual pair creation

›
We finally found a classical analogue for virtual pair creation. In the Feynman vacuum polarization diagram, if there is a virtual pair ther...

Lorentz invariance and time symmetry are broken by Feynman rules

›
Definition 1. In Proposition 1 of the previous blog post we introduced an exponentially decaying factor which attenuates the Feynman formula...
