The following two claims are true: - The universe is 13.7
billion years old. - The universe has always existed. It might
seem that these two claims contradict one other, but they don’t
if you recognize that time is finite. The universe has existed
for all time, and therefore the universe has always existed. The
only reason to think that these claims contradict one another is
if you assume that time is infinite. But all the evidence says
otherwise. Time is finite.
