I hve a question: IF there is no air resistance or ANY type of resistance in space, then how come an asteroid or fast moving object can crush a persons face in space (like in the movie: Gravity) My logic is the following: If you imagine a spring extended in space, and a fast moving ball hits the spring in one end, does the spring compress? If it does compress then there must be something in the other end of the spring (space) pushing against it right? Why would a spring compress if there is no resistance in the opposite side of impact? I would imagine the spring would just move. Even if you had one fragile egg in space and another egg moving 1000m/s crushing into the stationary egg,I would imagine both eggs would just move at half the speed of the 1 egg (the moving egg transmits ½ the movement onto the other), because IF there was no resistance in space then Could you not imagine this scenario: (This discription is happening in a split second) 1. The outer atoms of the edge of the fast moving egg, A, touch against the outer edge of the stationary egg ,B, this gives the egg a bit of movement. Now egg B is moving at 10th the speed of the the moving EGG, and the moving egg is loosing 1/10th of it's speed. 2. Egg B is still slower than Egg A,and Egg B keeps pushing harder and harder against Egg A (in a nanosecond) until they are moving at the same speed (because they are the same size, however the force of impact did not crush egg B or A because there is no resistance pushing in the opposite side of impact on egg B, so nothing is forcing the shell to crack from the opposide side of the impact site.) Are there any experiments confirming or explaining this?
