JoeJoeTom (aka Eerie Tom)I took a little #astronomy in college so I have a v*e*r*y basic understanding of the physics involved, but I'm still just blown away that, despite distances, the earth keeps the moon in orbit, the sun keeps the earth in orbit, yet a rocket can beat the pull of gravity, etc.
Shoot, even when I'm on a plane, I'm amazed that big hunk of metal can lift into the air!
