Zylon, I know what I'm talking about.
No you don`t

Think about it; how could you be pulled downwards, without gravity?
Look at the example I gave above. Why are you pulled sideways by a conering car if G-force is caused by gravity?
Also if G-force is caused by gravity how do you explain that a fighter pilot can pull negative G manouvers where he actually starts to weigh less?
Remember that gravity (on Earth at least) is simply an acceleration of 9.8m/s/s. If you experience another strong acceleration it can cancel out or increase the pull you feel towards Earth.
Oh and about there being no G-force in space. Here's a quote from a space shuttle astronaut.
From http://spaceflight.nasa.gov/feedback/expert/answer/crew/sts-92/
Question: What is the g-force the astronauts experience during a launch?
Mission Specialist Koichi Wakata : At launch the gravity that we experience is about 1.7 g's and by the time the solid rocket boosters are separated which is two minutes into the launch the g-force will be over 2 g's. At the separation of the solid rocket booster, the g-force will decrease to just over 1 g. During the last one minute of the ascent, which is for 8.5 minutes, when the main engines ignited the last full minute, we will experience about 3 g's, and when the main engines cut off around 8 minutes, 30 seconds, you go right into zero-g and everything starts to float around.
Notice that the second the astronauts cut the shuttles engines they go from 3 gravities to weightlessness immediately.
Here's a link where they talk about including a centrifuge gym on space stations and a future mars missions.
http://www.space.com/businesstechnology/technology/artgravity_spindrs_001107.htmlThe idea of the gym is to produce an area on the station where false gravity exists so that astronauts can prevent bones becoming brittle. Why would MIT and NASA be wasting time on something like that if there is no such thing as G-force in space?
