@metal-brain saidTell me how you get time dilation without either going fast or going into a gravity well. If there is neither, there is no 'time dilation'. That means time dilation is an effect not a cause.
"Who gives a shyte whether time dilation causes gravity or not?"
"Why all this quibbling over semantics?"
You mean the quibbling over a hyphen? I agree, humy never should have brought it up.
"Prove it if you think that is deeply important and at the same time explain why it matters what causes what."
I did by quoting Greene. It isn't my fault ...[text shortened]... ndescending without any justification at all. In other words, you made a big frigging deal about it!
The root cause is mass or velocity. There is no way to get time warps without one or the other. Even going fast is a case of increasing mass too, they go hand in hand so it is mass creating gravity and time changes.
