So right now you are sitting comfortably in your chair, eyes on the screen, reading these words. But you are Wrong. You are actually hovering above your chair. And it’s a scientific fact.
Everything you can see, touch, and feel is made of atoms - the infinitesimally small constituent parts of matter. Almost all of the mass of an atom is concentrated in its nucleus. Surrounding the nucleus is a whole lot of empty space with electrons and protons orbiting around.
Electrons have a negative charge. On the other hand, electrons are both a particle and wave. Particles are, by their very nature, attracted to the particles with an opposite charge, and they repel other similarly charged particles. This prevents electrons from ever coming in direct contact (in an atomic sense and literal sense). Their wave packets can overlap, but never touch.
No matter how hard they try two electrons can never touch. They just hover above each other. The same is true for all parts of the human body which are made up of atoms. When you sit in a chair, or slink into your bed, the electrons within your body are repelling the electrons that make up the chair, you are hovering above it by a unfathomably small distance. So, atomically you can't touch anything.
I know now you might think that, If electron repulsion prevents us from ever truly touching anything, why do we perceive touch as a real thing? The reason it that, It’s just interpretation of the physical world by our brains. Our nerve cells send signals to our brain that tells us that we are physically touching something, the sensation of touch is given to us by our electron’s repulsion from the electromagnetic field pervading spacetime.
