starship-design: Re: Quantum Gravity

Hi Zenon,

I guess the article suggests that. However like Lee suggested, the cells may
be streched, something that I haven't seen in cellular automation.
(Indeed this doesn't change the speed of c locally.)
I also wonder how one would incorporate effects like timedilation into
cellular automation.

Speaking about time... How does this ring-universe see time? Is it
continuous or discrete too (like in cellular automation).

That too could be the case.

Maybe most mistakes will selfcontain. If you get uncontrolable mass/energy
creation, you may create a blackhole which on its turn can loop ZPF around
and separate the anomaly from the rest of the ZPF.
Other errors may collapse to the lowest energy state (that of normal ZPF).

Of course in local environments the effects are likely to be catastrophic.
