One of the strangest features of string theory is that it requires more than the three spatial dimensions that we see directly in the world around us. That sounds like science fiction, but it is an indisputable outcome of the mathematics of string theory.

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll find molecules, atoms, sub-atomic particles. Probe the smaller particles, you'll find something else, a tiny vibrating filament of energy, a little tiny vibrating string.

Truth is, I think, if God just gave us our daily bread, many of us would be angry. 'That's all you're going to give me? You're just going to give me enough to sustain me for today? What about tomorrow or next year or 10, 20, 30 years from now? I want to know that I'm set up.' And yet Jesus says just pray for your daily provisions.
