Bill, I'm not sure which viewpoint the balloon analogy supports. No doubt Bill6 will point out that unless the balloon was made of solid material it would not cause the dots to move apart.

Tackling the question as to whether space works the same way is something we probably need to come back to when this particular issue is resolved.

I'm going to give it some thought, and see if I can come up with something devastating. smile

There never was nothing.
