Suppose you have a tennis ball in your hand. When one would throw it towards a wall such that it encounter the surface of the wall at almost a right angle, the ball would come back in the same direction. Now let us suppose the same scenario but as soon I throw the ball, place a similar wall at my place. Now the ball would bounce back from the first wall and strike the second, bounce back and strike the first wall and this would continue.
Now suppose there is a very very long swimming pool, filled with a fluid which has particles with very less mass, very less inter particle forces of attraction and coefficient of restitution equal to 1. Now I jump into it and be near one end of the pool. Now I push the fluid behind me towards the wall of a pool, and as in the case of a ball, the particles will strike the wall with some force F, with Newton's 3rd law, return with F and hit my back with F. I will get accelerated with F/M( where M is my mass).Again with Newton's 3rd law, my back would also push them with F( where my back is acting as the second wall as in the case of the tennis ball) then they would return to the wall then again push me ,accelerating me, and then I would push them. Since the pool is very long, I would keep on getting pushed and pushed and so increasing my speed and maybe I will beat sound and since it is so long, get somewhat near light. I know that the coefficient of restitution of my body is not 1 but we can some what increase it to near one by having some sort of suit.
Is this possible? Are there any flaws ? What are they?
