Big Bang Left Us with a Perfect Random Number Generator

Want a FIPS 140-2 RNG? Look at the universe. The cosmic background radiation bathes Earth in enough random numbers to encrypt everything forever. Using the cosmic background radiation – the "echo of the Big Bang" – as a random number generation isn't a new idea, but a couple of scientists have run the slide-rule over measurements of the CMB power spectrum and reckon it offers a random number space big enough to beat any current computer.

Not in terms of protecting messages against any current decryption possibility: the CMB's power spectrum offers a key space "too large for the encryption/decryption capacities of present computer systems". A straightforward terrestrial radio telescope, this Arxiv paper states, should be good enough to make "astrophysical entropy sources accessible on comparatively modest budgets".

    Cosmic background radiation is not truly random, it's part of the intelligent design - if you hold the same attitude toward God as most of the Manhattan project members.
