Don't forget, we didn't test general relativity through experiments.



WHOA! Oh yes we did! Einstein was considered a crackpot and his theory completely ignored until Sir Arther Eddignton did a test of the bending of light after an eclipse and the bending was in complete accordance to the theory.

Therefore we assume that Einstein was right



But he is right... in the realms that his theoy is valid. That we may need to add to the theory to make it compatable with QM doesn't make it wrong, merely incomplete.

As far as I see it, Brian Greene is wasting his time on something that



I disagree. Like Einstein, several theories started off as purely mathematical artifacts until tested. It will be through Greene's and others works that we can finally get to a stage where we might be able to test it. At that stage, SS may be proven right OR wrong. And even if wrong, it will have at least excluded that line of thought from Grand Unified Theories. Not a waste of time, but not worthy of complete belief right now either!!!
