I know this is a very common question but I've been seaching in forums all the time and couldn't find a clear answer. So quantum physic say that we can't actually "touch" anything because of our atoms( we're all made of atoms and they repel each other). correct me if I am wrong,please.. atoms indeed can't touch each other, so does that mean that people(who are also made of atoms) can't actually touch each other either? for example if we hug someone we don't actually hug him? Or don't I touch my keyboard now ? Just examples, can't think of something else. I am very curious about that, and I would appreciate an answer from someone that knows about this subject. thanks!
