QM: Does Time exist?

I didn't mention Einstein. I've been a regular visitor of a number of science forums over the past 20 years or more, and crackpots who claim Einstein's theories are wrong are a dime a dozen. Most have a flawed understanding of the theories, and their claims are easily refuted. A common mistake is to refer specifically to Einstein as if he is THE authority on the theories, failing to recognise that more than 100 years have passed since Einstein published those theories, and that those theories have moved on since Einstein.

 

What is your understanding of general relativity? When I said that I know that the gravity with which we are familiar is a consequence of gravitational time dilation, it is because I have personally done the mathematics that establishes this result. One thing about mathematics is that, with the appropriate skills, anyone can do it. It's not subject to the deception that conspiracy theorists claim exists in science. General relativity is a highly mathematical theory, and I see its essential correctness as a result of its mathematical underpinning more so than its many experimental confirmations. However, the Pound-Rebka experiment does more or less prove that the spacetime surrounding earth is curved. Science doesn't normally speak of proofs, but because spacetime curvature is the result of a measurement, it is a factual notion. I say this because it seems to me that many people think of spacetime curvature as an abstract notion. But as a factual notion, it is clear that this must be THE cause of earth's gravity.
