Well, that might be a good explanation for the reason the short legged ants failed to arrive home. However, it doesn't explain why the artificially leg lengthened ants overshot their nest. I mean, if it were you or me, we would have seen our home and stopped, so the ants must really heavily rely on step counting.
But the ants were moved so that they would never actually reach there home. So it makes perfect sence that if the Ant got to where he thought the nest was, and it wasn't there he might carry on further. Thus explaining why he overshot. The stilts being irrelevant.
I'm curious as to what exactly Partially Infinite means?
Just another way of saying: Not infite?
Or its not quite inifite yet, but it will be?
Or does it mean that some of it is infinte but other bits aren't?
Black holes can certainly roam. They are no different from other interstellar bodies in that respect.
Think of it! With VLSI we can pack 100 ENIACs in 1 sq. cm.!
