How Do You Measure the Size of the Universe?

Season 2015 - Episode 3 - 0h 7m

Air Date

February 25, 2015

Overview

The universe is HUGE. 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?
