Reminds me of the "thousand monkeys at a thousand typewriters" thought experiment.
As a side note, I think that this confirms my pet theory concerning time travel: any attempt to do it will change the past, which changes the conditions of the travel slightly, which changes the past, and so on, until the travel never occurs and the past stops changing. In other words, a spacetime where time travel happens is unstable and decays into one where it won't. Quantum uncertainty would, in this interpretation, be there to allow causality to "stretch" enough to allow such decay; a hypothethical universe without quantum uncertainty but with sentience and time travel (which is an inevitable outcome of the Theory of Relativity, which in turn is an inevitable outcome from the laws of physics being the same for all observers) would tear itself apart. You can thus deduct the Uncertainty Principle from the Anthropic Principle (we are here, so this universe must be able to support sentient life).
I wonder if you could calculate the minimum required amount of uncertainty for spacetime to stay consistent, and how it would relate to observed/otherwise calculated values? Assume that the first singularity formed at t=0, and has been moving infinitely close to lightspeed ever since, and connects to every other time period through a wormhole, and go from there. The math is beyond me, does anyone else care to try?
