Hi there. I know I am just jumping in, but I just wanted to contact you. I posted a question that admin said didn't justify a thread, but suggested that maybe you could answer.
How can the observable universe be larger than the age of the universe if nothing travels faster than the speed of light?
If for example 2 elements were relatively close at the BB, and now one is in our galaxy and the other in the far reaches of the observable universe, how could it have traveled more than 13+ light years away given the time it has been traveling?
Please excuse any misuse of terms, just trying to get my question across in an attempt to get past this mental block.
Thanks

Re: Expansion speed
OK, so I think I've got it now. The expansion of space itself is not subject to any speed limitations.
Should this give the appearance of a stretching affect as we observe light from these galaxies moving with space at speeds greater than the speed of light?

Thanks All
I,ve been away for awhile (I am a shift worker). I'd just like to thank everyone for helping me put all of this together in terms that I can understand. The paper on superluminal expansion was also key.
Cheers
