How many Planck times would there be from the Big Bang to the Big Rip? (approx.) Does this number have any numerical significance to mathematics?
If you had a CPU clock which had a timer counting from the big bang. How many bits would the CPU have to be?
If you took the number of 4 dimensional plank volumes from the big bang to the big rip bounded by the visible universe at any time. (which would give a double-cone shape.) What number is this? How many bits for a CPU need to express this number.
I'm just thinking about how what the maximum number of bits an immortal computer would need and not run into any Y2K problems!
