I've been doing a bit of reading into cosmology and it's pretty heavy going (being completly out of my field). I've been reading about the big bang (please don't groan) and it seems to me that every thing is expanding (in terms of space/time): now, does it mean time as we experience time (with a directional arrow) is expanding, too? Is this just some cock-eyed idea I've dreamt up by not grasping the maths and it's really a non-question or is time actually expanding in a measurable way (in the same way the expansion of space is taking place)?

I'm begining to think this is a non question (thanks Catholic Scientist!). But if this does have merit as a question please chime in (especially if you know cosmology/physics).

So if the sphere is expanding does the longitude time line 'change' as the relative curve of the sphere decreases? Or is that just a side effect of the analogy and not important? I fully appreciate I may have totally missed the point of your example and may be taking it far too literally.

Catholic Scientist writes: As the circles of latitude expand, does the magnitude of the time dimension get relatively smaller comapared to the magnitudes of the spacial dimensions? I mean, since the longitude line stays the same "size" as the latitude lines expand, is time shirinking relative to the expanding spacial dimensions? Yes, that's exactly the reverse of what I was thinking!  But it is a 'change' in time relative to space. Again you put my thoughts into better words than I ever could have.

We could never percieve it anyway. I've been thinking in a too fancifull way again, have'nt I?. A pox on this conventional universe. I really must learn some more maths so I can stop having to use ananlogies.

It is possible: it equals one.

Re: Re-Expansion
Space has expanded, but physical objects in space maintain the same dimensions (the forces holding them together ensure this). Does this expansion have any effect on vacuum energy? Does it get more diffuse as space expands? I'm sure I'm thinking like a layman here, so if it's a non-question I'm cool with that. Edited by Larni, : No reason given.

Re: Re-Expansion
So, you can't give me a straight answer? Congratulation Cavediver, you have just proved that God made the universe I hope you're happy with yourself
