You are made of space-time
LEE SMOLIN is no magician. Yet he and his colleagues have pulled off one of
the greatest tricks imaginable. Starting from nothing more than Einstein's
general theory of relativity, they have conjured up the universe. Everything
from the fabric of space to the matter that makes up wands and rabbits emerges
as if out of an empty hat.

It is an impressive feat. Not only does it tell us about the origins of
space and matter, it might help us understand where the laws of the universe
come from. Not surprisingly, Smolin, who is a theoretical physicist at the
Perimeter Institute in Waterloo, Ontario, is very excited. "I've been jumping up
and down about these ideas," he says.

This promising approach to understanding the cosmos is based on a collection
of theories called loop quantum gravity, an attempt to merge general relativity
and quantum mechanics into a single consistent theory.
