Space Travel
Did you know staying in Orbit requires very little energy. Once up to 5 miles a second. The rate of fall (due to gravity) will balance the vector of flying off in a straight line. To return to earth you just need to decelerate.

I had the thrill of operating a Space Shuttle simulator one time, docking with the ISS. It was fun, but it took a lot of getting used to the reality of speeding up and seeing my orbit altitude increase away from my target.

@Lisa82 My knowledge of tensors is somewhat shaky now, so I cannot develop this further.
Newtonian Physics gives an adequate explanation though. The speeds are very small.
Personally, I like the flat Earth understanding of the Universe, I like to think of the Sun crossing the sky during the day, and the stars fixed to the dome at night.

Fascinating! Not intuitive.
yeah. and it's easier to have that kinda speed when there's no atmo to get in the way.
satellites be out in orbit singin ludacris to air molecules. or at least on the way up, maybe on the way back in, too.
