I was a first level Maths student, but how does one prove a theory like that......
One of the many problems with String Theory it can neither be proved nor disproved.

The biggest flaw with String Theory when applied to Cosmology is that space time has to be flat for the theory to work. Given that the expansion of the Universe is accelerating there is a possibility that an open space time geometry exists which presents new challenges to the theory.

Then of course there are 5 different string theories in existence. No one is certain which is the appropriate theory for the Universe.

As you may gather I am not a fan of the theory or theories.
