explain how we levitate on an atomic level, is this true and how does it work?

Answer 1

On an atomic level, the atoms on the base of your feet are actually being held away from the atoms in the top of the floor by electrical charges. The amount of charge is extremely small, so the gap is also extremely small, but it is there.

This applies to any object that touches another, the physical atoms never actually touch.

Answer 2

On atomic level we all consist of tiny balls (Atoms; protons neutrons, electrons, positrons,...; quarks, strings,... the latter are not dexribed properly by balls) and the space in between. In fact the space in between is the majority of any given lump of matter.
Taking this into consideration there is no solid matter. So to speak even when having both feet planted firmly onto ground there is still the atomar "space" between feet and floor. Is that what you call levitation?
