Quote:Actually it doesn't really prove that.
I never said it proved anything. I said it was evidence.
Quote:Many people see E = mc^2 and assume its true. This means that they assume that its valid in all concievable situations. It turns out that is incorrect. There are instances where that relation does not hold.
I know it doesn't hold for quantum mechanics, is that the situation you were talking about?
Quote:It is often said that Einstein proved that gravity is a curvature in spacetime. Almost all relativists nowadays will agree with that statement. My question - Is it true?
Whether it is true or not is not something based on how many people subscribe to it. Such is a logical fallacy. If however these people all agree and all have evidence that supports their claim then I can say that it is supported well.
Quote:It is also often said that the mass of an object increases with speed. Is that true too?
Again, a logical fallacy to say that "it is often" and come to the conclusion that it is true, so I would simply say that if the evidence supports it and there is a lot of evidence, then it is highly supported.
