Loop quantum gravity increases its pull
String theory's main rival has earned the right to be taken seriously - it could be the most profound scientific generalisation of all time.



THE accepted idea of matter is that it is made up of minuscule particles guided by quantum force fields. This is already far removed from the common-sense view that matter is, well, just chunks of stuff. If that seems hard enough to take, then brace yourself for another step away from common sense.

Theoretical physicists working in the rarefied field of loop quantum gravity have developed a way to describe elementary particles as merely tangles in space. If they are right, it could be the most profound scientific generalisation of all time, in which everything in the universe emerges from a simple network of relationships, with no fundamental building blocks at all.
