Just the other day I heard a "science" person say the nearest star was billions of miles away (I think it was on dropout TV, but it may have been YouTube), and I understand that billions may as well be unreachable, but trillions is a not a non-understandable number. Why do we want so badly to scale things to dimensions contained in our own solar system?
To demonstrate how mind boggling huge space actually is.
I like the demo where the guy puts a pea for the sun on the ground, a tiny dot for Earth and then drives out of state to put down a radish seed to display Proxima Centauri to scale. It shows those trillions of kilometers nicely.
Our Light makes it from the giant fusion explosion to us on the mud ball in 8 minutes. And 5.5 hours to the poor butt of a joke that is Pluto. So ... 4 years you say....
