What the @&#*$ do we know?

Did anyone watch this at all. It is a 2 hr show on I think it was HBO about Quatum Physics? VERY VERY COOL program. I recomend seeing it if u havn't, but to the point. There was a secion in the show about how we really don't tough anthing. Example, a basketball. This kid was bouncing a basketball, and he was explaining to this laddy that he really isn't touching the ball and the ball isn't really touching the court. He said "and don't quote me" the energy that I have and the energy that the ball has creat friction and force one another away before actualy touching you or the court. Now my question is. Could we increase the enrgy that we produce to push the object away at a greater distence? Instead of the ball coming within fractions of a Milimeter from touching your skin can we make it a millimeter or a centimeter or even an inch?

thanx

Seems to me that there is some confusion here as to what defines contact, but would a glove work?

no, the programme seems to be about the forces between molecules, and it's true.

when you stand on the ground, you aren't _really_ touching the ground. you're very slightly away from it, but it feels as though you are due to the forces. All atoms and molecules etc. have forces around them, like magnets. putting two together will cause them to push apart. this is what happens when you walk, catch a ball, or anything else involving forces of pushing.

think about this: the entire earth's gravitational force is pulling you to the ground. what is stopping you from going straight through it? the forces underneath your shoes, caused by the molecules underneath them.
