Quantum theory of gravity versus the general theory of relativity

### To which end will the atom spectrum shift in a gravitational field? To red or blue?

Specialists in gravity argue that the atom spectrum in a gravitational field (closer to the Sun or Earth) shifts to the red end. This entrenched delusion is based on a […]

### How does a photon moving in a gravitational field change its energy?

How does a photon moving in a gravitational field change its energy? A simple solution to the problem.

### Unexpected turn of the light

Specialists on gravitation, following Einstein, continue to use old (before quantum) ideas about motion. This leads to numerous contradictions between general relativity and quantum mechanics.

### Let’s study gravity with a laser

After the creation of the general theory of relativity, Albert Einstein predicted two new effects – deflection of light near the Sun and the gravitational shift of spectral lines.

### The Quantum Theory of Gravitation vs. the General Relativity on the example of an atom

It follows from equations of quantum mechanics for discrete energy levels of the hydrogen atom and its size that the energy of the photon which the atom emits is inversely […]
