So Einstein could have been wrong. Factor that into your sure theories of the universe. Humanity knows nothing.

Indeed he could have been. We have been attempting to detect these elusive waves at least as far back as the mid-50’s. Personally I’m doubtful that they will be detected.

But I am nevertheless curious as to how the scientists calculate the size of an event (galaxies colliding!!) required to produce a detectable wave.

Are the scientists guessing? Can they actually calculate the expected magnitude of gravitational waves?

I wonder. But then I’m a born sceptic.

Newton's equations are wrong, but they get us to the moon and they work very well for objects moving well below the speed of light. Einstein's equations basically reduce to Newton's equations at slow speeds. Thus, Einstein's equations are improvements of Newton's work. Physicists and Mathematicians are currently trying to improve Einstein's equations. The new work on deformation geometry, and on tensor valued functionals looks promising. In the end all these equations only approximate reality. My work is on studying simple bending, and one problem took me over 20 years to solve. The stuff that the real nerds are working on is mind boggling.
