Ok, just a question for you rocket scientists out there. In the movie, which I suppose you've seen, (excellant) Clooney unhooks himself from Roberts, who is hooked onto a space station. Clooney then drifts away at a pretty fast clip. I don't get it. Aren't they both drifting at the same speed in space? Can somebody explain this? Surely it isn't gravity pulling him down, cause they are far enough out for no G to be in play. Just honestly wanna know the answer to this basic science question.

The only way for Clooney to actually drift away would be if a force was applied to him, and in zero gravity away from a magnetic field he would continue to drift for millions of years, a dessicated corpse in a deep, lifeless 3 degree Kelvin vacuum of space.
Hollywood defies the Laws of fizziks. Like grand fireball explosions and accompanying report, there's no oxygen to make a blow up and sound cain't work in space neether.
If'n a 100 pound man in space pushes away from a 200 pound object, the both get away from each other, but at a 50% speed disparity.

That's what I'm trying to figure out, the force. I know Hollyweird plays a little loose with the facts to make a good movie, but I just thought I missed something here.

I haven't seen the movie, but I imagine that the space station itself is traveling at a high rate of speed. They also are not out of range of Earth's gravity, although it is weaker as distance increases. Remember, it holds the Moon in orbit.

I think not that you can figure out the Force, but may it be with you Obi

I believe this to be closer to the truth than not, the station is moving away from him , not he from the station.

Doesn't gravity work equally on big and small masses? They fall at the same speed in atmosphere.

I haven't seen the movie, but it sounds based upon the grade school riddle "What falls faster, a pound of feathers or pound of lead?"

On the subject of an explosion, there would be no sound in a vacuum, that is correct, but, as for the fire ball, that there would be. There would be a fire ball as large as the gases from the fuel of the explosion allowed with no oxygen added. This fire ball would be much larger than that with the same amount of fuel on earth due to the lack of atmospheric pressure. The fire ball would also behave much differently.

I hear Sandra Bullocks hair is always hanging in the right directions is that gravity or just cinematography.

Yeah, yeah, yeah, but I still don't have an answer to my question. If you haven't seen the movie you can't know. but I'd still like to know why Clooney is moving away from Roberts when they should be moving at the same speed. In fact, unless the station they are attached to is spinning, (Which the movie clearly doesn't show), the scene makes no sense at all!

well now I'm gonna watch the movie just so I can be a reputable source in your eyes

Now ya do. Perhaps. Let me 'splain. Some space stations spin at around 60 RPM creating a sense of gravity within the ship. Now if ole' Clooney is released from a spinning hull, he's "slung" outward by centrifugal force out into the deep, cold, nebulous void of infinite space.
A tumbling frozen corpse, until one day he enters a gravitational field of a planet and he's vaporized into his proprietary atomic elements. And the people gaze in wide wonder at the shooting star.

Sounds like some genuine hollyweird horse hocky ifn ya ask me.
I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago.

The space station was slowly spinning on its axis which is why Bullock was "hanging" from the straps and the elasticized tether between her and Clooney was stretched. When he released, he continued in a straight line instead of continuing tot circle the station. The elastic tether caused Bullock to drift back to the station. That Statics and Dynamics class was good for something.

Didn't George Cluny look like Buzz Lightyear in his spacesuit. I couldn't take the movie seriously cos of that.

Just a backup for Wade and James. It has to do with the spin of the space station. Basically, a tether allows for the station and Cluny to 'orbit' a center of mass. This is similar to the orbit of the moon and the earth wherein gravity is the tether. Once the tether is cut the two objects separate. It's easier to explain with pictures using vectors.

I thought it was one of the rules of Inairtia. There is no air in space so most bodies go away from Ia then stay near Ia.

Yeah, I suppose, but it didn't look to me like the station was spinning. And they had a lot of earlier shots of "spinning in space" for comparison. Maybe I missed it. I guess it's the only explanation that makes sense.
