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.
