Man, you gotta think outside the box.
Granted, quantum theory is pretty weird, but it was developed over several decades by a host of physicists, and several independently developed mathematical formulations gave the same answers.
So how long did it take the stodgy, skeptical world of science to give serious consideration to general relativity? Five minutes? Ten? Anyone want to hazard a guess as to why relativity was accepted quickly, and fringe science is rejected?
