Two Surfaces NEVER Touch, Including Your Finger Tips & Keyboard
 

 
I know I posted this a whiiillle ago in the KC, but I'm gonna repost this. I do this because this is one of the most fascinating things I ever came across. My jaw literately dropped when I heard this last winter on an astronomy podcast...




Did you know that we don't actually touch anything? You might say, "What do you mean? I'm hitting the keys on this keyboard, aren't I? On a macroscopic scale, it might seem in fact you are touching everything around you. On the contrary, we are actually not touching anything and we never have and never will (there are rare occasions but they don't happen in our daily basis).


The bunched atoms that we are made of have an electromagnetic field, Like magnets they also can repel each other. On a microscopic level, quantum mechanics tells us that there is actually a very thin space between every thing we believe to be 'touching'. So in reality, what we 'feel' is the repellency? of the two (or more) electromagnetic fields that come from the atoms itself.

Friction is just the effect of atoms pushing against each other. On a smooth surface, with few bumps, there is little friction. Most of the atoms can slide right by each other without actually pushing against each other.

But no surface is totally free of friction. If you examine any surface under a powerful enough microscope, no matter how smooth it appears to the nekkid eye, there will be bumps. This will cause atoms to come face-to-face. If the forces between one set of atoms (snow, in this case), are weak, those atoms get pushed out of the way. But this uses up energy. It's called 'friction'. If the atoms are joined by strong forces, as in rock, then they can't easily be pushed away. The forces between these atoms and your ski atoms, supposing that you were skiing on rock, might be enough to bring you to a stop! In either case, it's atoms pushing against each other, at a distance, (electromagnetically), that causes friction.

Only source I have found so far.

i now there is a source but find this hard to believe.I mean if i punch a dude in the face,knock him out,break his jaw,swell his face up,and break my hand i doubt "repellency" would do this...there are other examples that come to mind like this but don't feel like posting

I could believe that even a punch could be the result of the above...but what about penetration..like a knife cut? What would cause these fields to cut skin? the shape of the knife blade? also water does it repel..do we actually get wet?

Fists in motion pack a certain amount of force. Your hand passes it to the surface it "comes in contact with". Velocity and amount of force determines how the recipient surface deals with the force and trajectory.

Weak wooden surface will give way, a vault door would not.

yea that was another thing i was thinking...not so much a "stab" because i guess somebody could say the force would do it but just a cut.Just taking a super sharp knife and cutting ur skin

how do you explain the texture of items? does this theory mean that when we chew food we aren't actually touching the food? c'mon people..

"Contact forces" are actually electromagnetic forces. There is an electromagnetic (force) repulsion that occurs b/w the electrons of your hands and the electrons of the keyboard so they get close to each other, but never actually touch.

Just because two things aren't touching doesn't mean that a force(gravitational, electromagnetic and strong/weak nuclear) cannot be exerted by one item on the other. What we perceive as crushing,chewing or whatever is due to a force that is being exerted on the other item not because we actually come in "contact" with said item.

Exactly. The same applies to the food in your mouth when you chew.

As for a knife stabbing you, obviously the blade of a knife is much stronger than your flesh, due to the atomic structure of the blade being more tightly packed. Therefore the electro magnetic force is probably stronger and when the blade and skin come in contact, the EM force of the blade overwhelms the skin and rips the atoms of the skin, which is seen as a cut.

If you had a strong enough microscope, you could see bumps on any and every surface, regardless of how smooth you really think it is. If you dip your hands in water, the same principle applies that there will still be a thin layer between the water and your hands. Due to the fact that the surface of your arm not being truly smooth, the water molecules separate because it is a relatively weak molecule which probably explains why when you dip your hands in water, the water is not covering your entire hand like a glove. And gravity and waters weight help most of the water get off your arm.

Well this is my take on it any way.

^You're not jumping off the building with enough force to break through those atoms...so, no. Which is pretty much what there are doing the the "Large Hadron Collider".(Clearly not jumping off buildings, but breaking through that force in-between objects)

I learned this as a freshman, it's interesting.
