I heard that you can never really touch anything. I also heard from an article that the reason why your butt doesn't fall through your chair is due to forces.
Here is a short excerpt:
"Cracking like lightning through the void, all the specks of electrons and the specks of nuclei are constantly interacting through a force called electromagnetism. Each interaction is carried out through the jolting exchange of particles of pure energy called photons (which is really just a nubbins of light). Each photon swapped equals a little push or a pull — a force — exerted across the emptiness. That's really what's keeping the stuff we call your butt from drifting through the stuff we call your chair."

So when I apply a force to an object, how exactly is the force transferred from my hand to the atoms that make up the object? Like what atomically in my hand carries the energy to be transferred? Is it photons? If so how does it know how much energy to transfer?
