Anyone else think that the smallness of this comic is unusual? I can barely read the mirror. TheHYPO (talk) 14:41, 24 October 2012 (UTC)

Text on the mirror is larger than it appears.


I think title text refers to the expansion of the universe and the speed of light. The observable universe is viewed from light that originated in the past. The further away the object, the further back in time we observe it. In an expanding universe, the universe we observe today is actually how it looked in the past (smaller) and we are unable to observe it's present size (larger) due to the great distances and the time it takes for the light to arrive. Thus, the universe is larger than it appears, no matter if you view it traveling towards or away from any object. --Bpiltz (talk) 15:47, 24 October 2012 (UTC)
