Question

Do all solutions of general relativity work in the real universe?

Answer 1

applications of General Relativity include such diverse phenomena as the perturbations of the orbit of Mercury and the Big Bang.

Answer 2

The major precepts of general relativity are -

1. acceleration and gravity are equivalents

2. mass distorts spacetime via a phenomenon we call gravity

3. gravity bends the path light takes

All of these have been proven valid over and over again by every imaginable kind of experiment.

Answer 3

They work within the limits of what we can verify. It is a mistake, however, to assume that they work at the scale of quantum physics or at the scale of galaxies and beyond.
