@dave What do you think, 64 bits be enough?

@dan613

Since there are ~10^35 plank lengths in a meter and the observable universe has ~10^26 meters, this means a direction has 10^61 addresses (2^203). So we would need about 3*203 = 609 bits for the address space of three dimensions.

Making each position addressable in time would add another 203 bits (!! this blew my mind) giving an address space of 812 bits.

Might as well round it up to 1024 bits to be safe :)
