And 10! seconds is exactly 42 days. Not an approximation.

  That's not really a fundamental coincidence, but a result of the mechanics of factorial and our time system. 10! = (10 * 9 * 8 * 5) * (4 3 2) * (7 * 6) = 3600 * 24 * 42 3600 = 1 hour in seconds 24 = 1 day in hours Waaay less a "coincidence" than strange (approximate) relationships between the fundamental constants of mathematics

    42 is not a mathematical constance? It is the answer to the ultimate question of life, the universe, and everything. This is demonstrated by 42 being: Represented by 101010 in binary; The refraction angle of light off water in the forming of a rainbow; Light requires 10^-42 seconds to cross a proton; as well as being the result of 6*9. Or have I simply been misled?

    This is also highly dependent on how you define a day. A sidereal day is < 24 hours.

  More interestingly, 10! seconds is exactly 6 weeks.
