I’ve read plenty of numbers about how big the solar system, the galaxy and the universe are. But it’s hard to really appreciate when a long list of zeroes at the end of numbers mean. Which is why this image is so brilliant:
It comes from a great post on the Fermi Paradox – that is why, given how huge the universe is and how long it has been around, haven’t we yet found signs of intelligent life elsewhere?
By the way, if you’re ever in Somerset with some time to spare, make a trip to the Somerset Space Walk along the Bridgwater and Taunton Canal – it’s a great sculpture that shows just how large our galaxy is in a wonderfully physical way given its size.
