I've seen children's eyes light up when I tell them about black holes and the Big Bang.

I enjoy reading blogs, but am not interested in having my spurious thoughts out there.

I would say in one sentence my goal is to at least be part of the journey to find the unified theory that Einstein himself was really the first to look for.

I believe the process of going from confusion to understanding is a precious, even emotional, experience that can be the foundation of self-confidence.

String theory has the potential to show that all of the wondrous happenings in the universe - from the frantic dance of subatomic quarks to the stately waltz of orbiting binary stars; from the primordial fireball of the big bang to the majestic swirl of heavenly galaxies - are reflections of one, grand physical principle, one master equation.

There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.

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