Every string theory that's been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of light has actually increased.

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.

I do feel strongly that string theory is our best hope for making progress at unifying gravity and quantum mechanics.

In essence, String Theory describes space and time, matter and energy, gravity and light, indeed all of God's creation... as music.

Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics, but it reconciles Science and the Bible as well.

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