Thread: re: Einstein's theory of relativity

If I have understood correctly. Einstein said that the universe is a blanket/matrix of stuff. That there is no space. That there is no gravity. That the stars are just sitting in a depressed section of this matrix, and the earth, for example, is caught at the edge of this depression, within the blanket. Kind of like a whirlpool without the whirl.
So, how are we moving around the sun? If it is the stuff that is moving then we are all moving relative to the stuff and we would not circle the sun.

All I can say is that you have not understood correctly. Einstein certainly never said that "there is not space" nor did he say "there is no gravity". He does give a different formula for the gravitational force than Newton gave (but they reduce to the same thing for normal masses and distances). He did also observe that gravity can be understood as "curvature" of space in a highly technical sense. You appear to be thinking of the "rubber blanket" analogy. That is simply a (not terribly good) analogy, not what is really happening.

Ok. So, I didn't understand it at all.
Sounds like I should stop watching videos on youtube, even if the graphics are cool.
I think I will slow down a little.
