Just an interesting thought.... As I was looking up into the sky yesterday. I was admiring the wonderful effect of blue sky and clouds.
It makes me wonder if gravity can hold the air and our atmosphere then why do science fiction still shows the vending of air in space.
We can create artificial gravity today by spining things around i.e. using centripetal force. Then wouldn't the air be bounded by gravity... we are talking about space now not aircraft. If the gravitational force is strong then we wont vent air!
