Questions About Objects Touching?

When two objects are touching, it`s really electromagnetic force repelling the two objects (so the atoms never actually touch), right? Well, what happens if this force can be extended over larger distances? For example, a brick can be touching the floor without being close to it? In theory is this right?

Well the electromagnetic force dies off as an inverse square, so this probably wouldn't work. Also, the situation is more complicated than classical Coulomb repulsion. You've got electron bonding going on, as well as other forces that contribute to the macroscopic effect that we see in rigid objcts.

do you mean what would happen to human reality if you changed this law of physics?
perhaps a 1/R relationship instead?

Yes, as tot points out, if you change the laws of physics, you can do anything you want.

If you try to change the 'laws of Physics' you ain't got Physics any more. One of the first things to go wrong would be the Earth's orbit; it couldn't be an ellipse / stable. Also, Chemistry would be all to hell . . . . . .
