What if I told you: The floor you're standing on is empty space.

What if I told you there was no such thing as a solid surface?  And no, I am not smoking pot, I am reading a book by a prominent evolutionist, Richard Dawkins.

Consider page 412 of The God Delusion:

Science has taught us, against all evolved intuition, that apparently sold things like crystals and rocks are really composed almost entirely of empty space.

Dawkins goes on to give this illustration. If you took the nucleus of an atom as a fly and put it in the center of the Chief's stadium in KC, the next atom next to it would have to be placed outside the stadium. That is a lot of empty space between the two. So how on earth does a rock feel solid it it is almost all empty space?

This is how it works, It is not solid surface that keeps you from going through walls or falling through the floor, its a force field that exists between the atoms that prevents us from going through it. Those force fields can be broken with enough force, thus why a sledge hammer is a good way of taking out dry wall.

Now your eye balls receive light within what is called the visible light spectrum. That spectrum of light is large enough to bounce off of the atoms and not penetrate through them. Other bands of light like X-rays can penetrate but what our eyes can see cannot. Therefore, the light that bounces off and comes into our eye balls our brain interprets as "Solid."

Kinda makes you wonder what is really "REAL".
