so according to string theory and m-theory there is an infinite number of universe each with different laws of physics. and that every single outcome of anything is in one of the infinite many universes. so doesn't that mean that in at least a few universes string theory is wrong. so doesn't that prove the whole thing?

A theory is a theory, and only so until is is either proven or disproven.
Who's to say if it's right or wrong.
Theory states that we may reside in a universal community that consists of not only four dimensions (X,Y,Z, and time, itself), but a number (from 11 to 13) of other 'strings' we may inadvertantly be a part of.
There is no right or wrong to a theory, until it has been proven or not.

No, not at all. It just means that string theory and m-theory may need to be expanded into infinite-dimensional theories instead of finite-dimensional theories. Which will make a bit of a mess, but we already deal with infinite dimensional spaces in mathematics.

EDIT: Proof is lacking because the energies required to observe things happening at the Planck level are on the order of several million times the total output of the Sun. If Congress hadn't cancelled the SCSC(Super Conducting Super Collider) project, we might have been able to generate cross-sectional energies high enough to observe a few 'second order' effects from superstring theory.

Well, I don't think that proves anything. At most it illustrates a paradox of infinity.
I'm no expert on string theory, but here's my take on the debate at the moment; the supporters like it because it explains things that are otherwise difficult. It has gained some detractors, though, because it is difficult in itself and (the same old story) evidence is lacking.
right or wrong is simply up in the air right now. And it will be so for awhile unless some big break-through happens.
(I'm speaking in generalities simply because I don't understand it well enough to even form my own opinion)

11 dimensional string theory, (and 26 dimensional M theory), has not produced anything.
It is possible that the extra 7 dimensions of space in string theory, (that are not perceived), are mathematical deception that first appeared with 5 dimensional Kaluza-Klein Theory.
String theory is possibly deception involving adding dimensions of space to the already existing 3 dimensions of space one dimension at a time at 90 degree angles to the previous dimension.
That string theory is possibly invalid is stated at the end of the wikipedia article on string theory.

Which string theory are you talking about? There are about a dozen major types, and lots of variations. I don't know of any that include an "infinite" number of "universes". How can you have more than one of "everything there is"?
