Has String Theory Made Any Predictions?

String theory has finally made a prediction that can be tested with experiments — but in a completely unexpected realm of physics. ... The theory has long been touted as the best hope for a unified "theory of everything," bringing together the physics of the vanishingly small and the mindbendingly large.

Does string theory predict anything?

String theory simplified

Theorists can predict what a gravity particle should look like, but when they try to calculate what happens when two "gravitons" smash together, they get an infinite amount of energy packed into a small space — a sure sign that the math is missing something.

What will happen if string theory is proven?

If string theory is true, our universe has extra dimensions that lie curled up at every point around us. ... And some physicists now view strings as a failed theory because it doesn't make useful predictions about the universe.
