How old is the universe? Well the bad astronomy blog summarized some newly published data from NASA and tells us that it's 13.73 +/- .12 billion years old. But does that even make sense?
How does relativity fit into all of this and time dilation and contraction? All the different parts of the universe are moving toward or away from each other at different speeds, and so have different time frame references. So time moves at different paces in different neighborhoods, at least according to Einstein.
So how does measuring the age of the universe even make sense? Is that measured in Earth Standard Time? What even is Earth Standard Time relative to the universe?
