Doubly Special Relativity

Calvin and I have been reading a really interesting book about the politics of physic (yes there is such a thing called) “The Trouble with Physics”: about the big issues with string theory. Thanks to Peter for sending to me.

He describes a really interesting theory called “Doubly Special Relativity (DSR)”: that although highly speculative makes more sense to us then a 12 dimensional universe. Basically it says that just as there is a speed limit for light at C, there is also a smallest possible length which is called Planck’s length. As things get smaller and smaller (remember as you go faster, everything gets shorter and time gets longer, until you get to the speed of light when time stops and distances are zero), that the all observers can agree that nothing is smaller than Planck’s length with is
