Empty Space by John Hawkhead

mostly empty space

by John Hawkhead

Atoms are 99% empty space, comprised of electrons in orbits around a nucleus made up of protons and neutrons. It follows then that approximately 99% of the human body is empty space with the remaining 1% (the electrons, neutrons and protons) being particles that have existed for billions of years.

At least this is the common mental image of an atom – the planetary model, originally proposed by Ernest Rutherford in 1911 and further refined by Niels Bohr in 1913. And yet…

Researchers increasingly understand that whilst electrons occupy discrete energy levels, they don’t always behave like discrete particles. Electrons are quantum objects – an electron is partly a wave and partly a particle. Under normal conditions an individual electron isn’t traveling in an orbital path through nothingness around its nuclei, but is instead spread out in an electron cloud.

As astrophysicist Dr Ethan Siegel says, “Inside your body, you aren’t mostly empty space. You’re mostly a series of electron clouds, all bound together by the quantum rules that govern the entire Universe.”
