Question

When we slap someone lets say, our hand gets really close to the face which will result in electomagnetic relulsion. Is this repulsion really stong because if it is then that would imply that we actually never touch anything because of repulsion?

Answer 1

According to quantum mechanics we are really never touching anything. But the book you use to study, you really touch it while you read. You literally touch someone's cheeks while you slap. But no! According to quantum mechanics you are not touching anything. Now why aren't we touching anything? I will give you the answer in a moment. Before that I will answer why can't we touch anything. Inorder to understand we will have yo think at the atomic level. We know atoms are made up of protons neutrons and electrons. Electrons surround the Nucleus and we know they exist as a wave. When I try to slap your face. The electronic cloud at the tips of my palm will repel the electronic cloud at the tip of your cheeks and hence its actual repulsion.
But we have the perception that we are really touching it.
This is because the nerve cells of our body will send signals as touch signals when it is actually a mere electronic interaction. And hence that interaction is felt as a touch. You will learn more about this in higher studies
