If there were an infinite universe full of water, and there were two bubbles of air in it, would they move towards each other? Away from each other? Stay put?

If they moved close enough together to touch, would they coalesce into one bubble?

Would anything turn out differently if the universe were full of cold honey?

I don't have the answer--a couple of my friends who know more physics than I do kicked the initial question around. They and I have intuited the same answer, but no one has a proof.

Just wondering about that infinitely large black hole--obviously, there's no particular location where it would form. I suppose random motion could cause small increases in density (in water? maybe not) which would start a positive feedback process.

Still, what with infinity, I'm not sure that all the black holes would catch up with each other, and an infinite number of infinite black holes seems as likely.
