  Btw, I have never quite understood the reason why objects can't go
inside each other (given that objects are actually practically empty
space with staggeringly tiny corpuscules here and there, at relatively
enormous distances from each other).

  I have of course heard/seen the explanation in passing in many situations,
but I have never quite understood it.

Thanks for the link.
I remember a pure joy of reading his book
"Surely You're Joking, Mr. Feynman!"

Electrons are emitting and absorbing virtual photons in huge numbers all the 
time. (It's the same thing keeping the electrons in "orbit" around the protons.)

The photons go between the nearby electrons in your arm and in the chair, 
changing the motion of both electrons such that they do not continue getting 
closer to each other.

well, you'll just have to take it for granted... :)

or indeed gulp up Darren's fine explanation, at least as far as you're prepared
to accept virtual photons having a very real consequence.  I wish virtual money
had the same effects... :)

  I didn't understand that at all.

Your ass is supported by beams of light? :-)

Basically, all electrons are constantly emitting and re-absorbing photons. 
When two electrons get close enough, they start emitting photons that the 
other electron absorbs. This changes the motion of the electrons such that 
they won't get too close to each other.

I can picture Feynman saying that. :)

  I still don't quite get it. Well, I suppose I will have to submit to the
fact that I have never understood it, and I still don't understand it.
