I think the statement, "the common view among cosmologists is that the universe comprises more than the three dimensions that we see, and that the universe is expanding in another dimension," is incorrect.

The expansion/contraction of the universe is governed by general relativity, which is a theory about the intrinsic geometry of spacetime. As such, the universe isn't really expanding into another dimension like a balloon would, but rather there is an increase in distance between two nearby points in the universe over time, which is colloquially interpreted as expansion. I'm going ahead an changing this to avoid confusion. However, the analogy drawn in the next paragraph is a good one. --[[User:Quantumdot|Quantumdot]] 20:50, 25 March 2008 (EDT)

==Questions on Age==
In the source material given as evidence that the ''measurable'' age of the universe may not truly reflect the ''actuall'' age of the universe, it is stated that because clocks run faster at the top of tall buildings, and that this is evidence of time running faster, because of the decreased effect of gravity. However, I cannot understand how the effect of gravity on a human instrument of measurement can be said to be affecting the actual time constant. That is; how do we know that it is not only our instruments which are affected by gravity, but the fabric of time itself? I find this article very interesting, though there are one or two more problems I have with it, I might need to read the book before I bring them up --[[User:Entheogenicorder|Entheogenicorder]] 16:59, 5 August 2008 (BST)
