As you say, the way string theory requires all these extra dimensions and this comes from certain consistency requirements about how string should behave and so on.

I'd say many features of string theory don't mesh with what we observe in everyday life.

Our best theory of describing space at a fundamental level is probably string theory.

Some string theorists prefer to believe that string theory is too arcane to be understood by human beings, rather than consider the possibility that it might just be wrong.

When I was in high school, I was really into string theory and superstring theory and read 'Scientific American.' It's fascinating.

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.
