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...

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...
