time and distance.. the two uncomprehendables.
How small we are in the universe. How far it is out there. All with time somehow interrelated.
If the nearest star is 4 light years away, as they say, that is truly amazing.
"The closest star to our Sun would be one of the three in the Alpha Centauri system. The system is only 4.27 light years from the Sun."

light year: distance light travels in one year at 186,000 miles/second (speed of electricity as well)
That is a loooong ways to the first star.
Amazing stuff.
