String Theory The string theory is an attempt to bring together quantum mechanics and general relativity. It is basically saying that it is possible to bring the two of them together that’s why the string theory is sometimes referred to as the theory of everything. If the string theory is proven correct then that means everything can be related. From the huge universe to the most microscopic particle on earth everything is somehow related. There are many controversies with the theory because there is no real evidence it is true. Personally I don’t know if I can actually believe in string theory. First of all it seems very confusing and I don’t really understand it. The theory just doesn’t seem to have enough backing it up to be proven true.
