Einstein Legacy: Ether Relativity and Cosmology

General Relativity introduced the geometrization of gravity. Einstein's field equations are considered one of the greatest intellectual achievements of physics. Their weak point is that they do not have a physical meaning. Einstein's field equations are meant to describe the gravitational force, but cannot be used to calculate it. For example, with the GR mathematics, we cannot calculate the gravitational force between the Moon and the Earth. The curvature of space is a geometric description of gravity, which the variable energy density of the ether, a new name, superfluid quantum space, can replace successfully. In 1920, Einstein became aware that general relativity without ether is unthinkable. The reintroduction of ether into physics describes gravity as a pushing force of space and introduces an evidence-based cosmology where black holes are the rejuvenating systems of the universe.
