Question: Since atoks are largely empty space and everything is made of atoms, doesnt that mean that if I ran into a tree I'd pass through it? And if so, how high of a chance

When we imagine the structure of atom in our mind a picture appears…nucleus and few electrons revolving around it in 2D structure…in reality it’s a 3D structure and the electrons revolve by obeying Heisenberg’s Uncertainty principle…it’s looks a cloud of charge with certain amount of energy associated at each level, bonding energy everything comes into play. When you would like to pass through a tree your atom will interact with the atom of the tree which will never penetrate through it because of its energy. Inter atomic bond energy makes something define how hard or soft is. So, basically it’s impossible to pass through.
