“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's long way down the road to the chemist's, but that's just peanuts to space.”
I like to tell people how big space is just by describing how fast voyager 1 is moving and how long it will take to reach 1 light year of travel. Voyager 1 launched back in the 70's and is traveling around 38,210 mph. Even at that speed it will take another approximate 18,500 years for it to reach it's first light year traveled. The closest star is about 4.2 light years away so at it's current speed it would take about 75,000 years for it to reach Alpha Centauri.The more you start getting into the numbers and things like how many light years across the milky way is and how far to the next galaxy and how many galaxies their are you start to see the universe is unimaginably large. I don't think one could fully grasp it's size. Amazing
