"Space … is big. Really big. You just won't believe how vastly hugely mind bogglingly big it is. I mean you may think it's a long way down the road to [Smith’s], but that's just peanuts to space."

8. Distances in terms of the speed of light.
Moon light seconds.
Sun- Eight light minutes.
Solar System Diameter – Twelve light hours (eight billion miles).

9. When we leave the Solar System, we need a new unit of measurement.

10. The new unit is called a “Light Year.”
A light year is the distance light travels in one year.
One light year = six trillion miles.
