Question

How many experiment do we need to prove a theory?

Answer 1

There is no experiment that will ever conclusively prove or disprove any theory. There are only experiments that support or refute the claims of a theory/hypothesis, and what is a valid number of experiments or data points necessary to make a theory generally acceptable changes dramatically from field to field.

Answer 2

The big difference between mathematics and physics is that we use experiments in order to prove a theory instead of some equations. Sure, we use equations a lot also in physics, but math in physics simply is, can be described as the brush and paint needed to draw the big picture of the universe. It isn't math really and the only way is trying a whole lot of experiments. All we can do is keep trying experiments. In my case, physics is interesting because we don't know when a theory we had once believed without questioning will become wrong all of a sudden.
So the answer to your question shall be, an infinite amount of experiments. It's not a joke; it's the reality and the true face of physics. Is it not depressing, if you had wished to learn physics just to realize only the truth of the universe? Is it not dramatic, to realize that all theories that we had seemed to know of might become, one day, some silly old lies that we might laugh at centuries later? Is it not tiring that we can never stop? Physics is like a supercomputer trying to solve the Fermat's Last Theorem, trying every case without knowing when it's going to stop.
