Atoms never touch each other because of electons

  1. Apr 30, 2014 #1
    Recenty I learned that there is not real touch. That atoms never touch each other because of electons. I have two question to this.

    1) Why we feel the pain(I think is because of brain analysys but I am not sure)
    2) Why if I press hard my hand,I will mark that?? Why this sign in my hand will be exists(I will get out the electrons from there?)

    Thank you!!!

    1-If you have no nerve connections there,you won't feel any pain.So that's only a problem with our brain.

    How are you marking?By paint or just pressing hard?
