But, there is only so much of the universe we can ACTUALLY see, and if we wanted to measure that FINITE space, how would we do it? A gigantic ruler? One really long car ride? Or maybe it s something even more spectacular, something that involves not only the observable universe as it is NOW, but how it was when it was first BORN? Join Gabe in this week s SpaceTime as he embarks on the quest to MEASURE THE SIZE OF THE UNIVERSE.
