Dimensional Reduction: the key to physics’ greatest mystery?
Could the secret to understanding gravity be held in reducing, not increasing, the number of dimensions?
Dimensional reduction is an attractive idea because quantizing gravity is considerably easier in lower dimensions, where the infinities that plague traditional attempts to quantize gravity go away. A theory with a reduced number of dimensions at the shortest distances therefore has a much higher chance to remain consistent, and therefore to provide a meaningful theory for the quantum nature of space and time. Not so surprisingly, among physicists, dimensional reduction has received quite some attention lately.
