Not Always Right | Funny & Stupid Customer Quotes... →
I just read 24 pages of these. Actually makes me want a weekend retail job. I must be sadistic.

It's not big, and it's not clever.
Seaden: There is no gravity in space
Sakurako Kimino: There is gravity in space... only it's very, very small. It's called "microgravity" because it is so small. Gravity affects everything, everywhere, although in space it is usually such a small effect that it can be ignored but it is there.
Avon: No, there are absolutely bloody huge amounts of gravity in space. People tend to think of zero-G because they see crazy spacemen tumbling through spaceships chasing spinning bananas, or globs of drink, or something equally silly. However, they are't weightless - they are just continually falling down at the same rate as everything else around them. If they weren't under the influence of earth's gravity they would shoot off in to the depths of sapce, rather than neatly orbiting the planet. Orbiting is just the ability to fall towards the ground and continually miss. It's not big, and it's not clever.
The nearest you can get to zero-G in near-space is at a Lagrange point, where the gravitational effects of the most dominant centres of mass effectively cancel each other out. (Assuming that you move with the Lagrange point to maintain your orbit around the influencing objects, obviously)
