Dark energy from retardation of gravity?

In our previous blog post we were able to derive an estimate for retarded gravity when a supernova core collapses to form a neutron star. We...

Type II supernovae explode because general relativity is wrong?

There is a major open problem in how type II supernovae are able to explode when their core collapses. In the photo (middle right), we have ...

Electron propagator controls bremsstrahlung in the Feynman diagram: how does it know how to do it?

In the November 10, 2025 post we realized that the electron propagator governs the form of the bremsstrahlung wave in the Feynman diagram. ...

Feynman diagrams miscalculate the box diagram and bremsstrahlung in the classical limit

In our blog post on November 10, 2025 we showed that Feynman integrals miscalculate several simple processes in the classical limit. ...

Quantum gravity: vertex correction, propagator, coupling

In QED, the vertex correction may be due to almost-bremsstrahlung which cannot escape as a real photon. https://arxiv.org/abs/hep-th/0211072...
