@metal-brain saidGreene said that gravity is caused by a "time warp", he did not say it is caused by "time dilation". Frankly I don't care if he did say that, I am certain of my position here. Time dilation is a disagreement between two observers about the amount of time elapsed between two events. What I think Greene is talking about is proper time, as I discussed above - or possibly in the other thread.
"It was an argument based on absurdity. It is absurd to suggest because time dilation happens when you go fast, that you could use time dilation as a propulsion system."
No, I never said it was absurd to have time dilation from velocity. Time dilation as a propulsion is a cool idea in theory, but nobody knows how to artificially create time dilation. It does not exist ...[text shortened]... e yet think twice. It makes you look like a flake.
Time dilation causes gravity. Greene is right.
