Current measurements of the age of the universe are 13.798±0.037 within the Lamda-CDM concordance model. My question is how is time measured given the relativity of time? Will all observers within the universe come to the same conclusion if they assume they are at rest? Is there are a way to measure the age of the universe in terms of how much distance light has traveled since the Big Bang? But then again how would we come up with a common measuring stick to measure the distance light has traveled.?
