- Why a world time scale? If I want a process over here going at 1
- nanaosecond per second, and another over there going at 2 nanoseconds
- per second, does that mean I can't? I think the best way is to throw out
- a "world time scale" and simply ask each of the objects to adopt a time
- scale with *certain other objects*. If they adopt it with every object,
- including you, then I think you will end up with some unreasonable
- behaviour. (eg, you push on the object with a force of 1m/s/s, and it
- takes 1.6 billion years to perform the action)

- Er, problem. What if I go straight from a world in which I had scaled
- myself up to galaxy size, then I zap over to another world that it at,
- as you say, the size of single cell. I've got to be able to see what I
- am doing before I re-scale myself, and before that I'm going to have all
- sorts of overflow problems due to not fitting in the world. Answer: Use
- 128 bit numbers, and "actual size" scaling. Accept no substitutions!
