How does discreetness imply imprecision and randomness? If anything, it should indicate some degree of certainty.

- hinoki 7y agoIt depends on your rules for rounding I think.
- akira2501 7y agoI'm an amateur, but I like to think about this: If spacetime is quantized, then the speed of light would be 1 planck length / 1 planck time. Assuming spacetime is actually quantized to that metric, we can then ask: How does something move at 2/3c? Or two discrete planck lenghts in 3 discrete planck times? In one instance it could be: t=0,x=0, t=1,x=0, t=2,x=1, t=3,x=2 It could also do: t=0,x=0, t=1,x=1, t=2,x=1, t=3,x=2. It implies a hidden variable, or at the very least a hidden phase of some sort. All sorts of oddness abounds when you consider all velocities are then quantized fractional values of c.

- Ono-Sendai 7y agoIf you can have real numbers at each spacetime point (as opposed to boolean values) then you can easily get a speed less than c. This is similar to simulating the wave equation on a grid on a computer.
