## Einstein’s neglected demands of GR solutions

loopdoctorOctober 26October 260Level III Doctor

The Theory of General Relativity is very complicated mathematics. Einstein formulated a number of demands to ensure that solutions match measurement physics. Exact Schwarzschild solutions have later been changed by astronomers, unscientifically, to get rid of difficult issues.The relevance is great: abiding...

Contrary to popular believe, there are many Schwarzschild Solutions. Karl himself found one to a mass-point and one to a sphere of in-compressible liquid early 1916. After Karl’s death Einstein made important changes in his official publication: he abandoned his g = -1 requirement in a footnote. Nobody checked...

## No ‘Event Horizon’ in New Time-like Solution

loopdoctorFebruary 15March 160Level III Doctor

Einstein’s General Relativity contains the Laplace operator of a sphere of incompressible liquid. It links the time-like solution (how fast does the clock tick) directly with the gravitational potential: no need for using tensor operations. He never applied it to the potential inside a sphere. This article is doing...

## Emmy Noether, the ignored scientist

It all starts with Emmy Noether (1882 – 1935), a brilliant mathematician, creating one of the pillars of physics: defining reference frames within which energy and momentum conservation can be proven. In 1918 Noether’s theorem was published, more than a year after Einstein published his theory of General...
