I've heard it said that to include a quantum theory of gravity in string theory that the model must include extra dimensions to explain the apparent weakness of gravity. First off, why? couldn't you just as easily say the universe is bigger than we thought and that's why gravity is so weak? And if you label the three dimensions of space and the dimension of time as dimensions, why isn't temperature a dimension of an objects existence, or any other fundamental unit of an object such as the SI base units of measure?
