Question and Answers.
How old is the Universe?
From what we can determine from measuring how fast the galaxies are moving away from each other we can make about that the universe it about 12.5 aeons old + 2.5 aeons (1 aeon is one giga-year or 1,000 million years). This can be done by looking at the Andromeda galaxy that is 2.2 million light years. Measuring how fast this is moving away we can work back to when both galaxies are at the same point in space and this was around 12,500 million years ago + 2,500 million years.
