Sqrt(2) “any unit that is an integral multiple of the shortest interval”.

But it would get complicated, for any given allowable velocity and allowable length, you’d get more lengths from Lorentzian contraction.

There are really a couple of different ideas being combined: are there an infinite number of quantum states for the universe, are space and time continuous, is the forward direction of time resolved by computable processes.

And even bigger ones lurk: are space and time emergent properties from quantum waveforms that lack an inherent idea of space and time (but things that are highly correlated give rise to a notion of being near each other in “space time”)?
