My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

I think the discovery of supersymmetric partners for the known particles would revolutionize our understanding of the universe.

Why are we here? Where do we come from? Traditionally, these are questions for philosophy, but philosophy is dead.
