This Is Why Space Needs To Be Continuous, Not Discrete

INTRO: If you try and divide matter into smaller and smaller chunks, you'll eventually arrive at the particles we know of as fundamental: the ones that cannot be decomposed any further. The particles of the Standard Model — quarks, charged leptons, neutrinos, bosons, and their antiparticle counterparts —  are the indivisible entities that account for every directly measured particle in our Universe. They are not only fundamentally quantum, but discrete.

If you take any system made up of matter, you could literally count the number of quantum particles in your system and always wind up with the same answer. But that's not true, as far as we can tell, of the space that those particles occupy. Observationally and experimentally, there's no evidence for a "smallest" length scale in the Universe, but there's an even bigger theoretical objection. If space is discrete, then the principle of relativity is wrong. Here's why... (MORE)

You are not mostly empty space

EXCERPT: . . . [...] we've recognized that these models are too particle-like to describe what's actually occurring. Electrons do occupy discrete energy levels, but that doesn't translate into planetary-like orbits. Instead, the electrons in an atom behave more like a cloud: a diffuse fog that's spread out over a particular volume of space. When you see illustrations of atomic orbitals, they're basically showing you the wave-like shape of the individual electrons.

If you were to send a high-energy photon or particle in there to interact with an electron, sure, you could pin down its position precisely. But — and here's where quantum mechanics trips most of us up — the act of sending that high-energy particle in there fundamentally changes what's going on inside the atom itself. It causes the electron to behave like a particle, at least for the moment of that one interaction, instead of like a wave. But until such an interaction occurs, the electron has been acting like a wave all along. [...]

There's a big problem whenever we rely on our intuition to make sense of the Universe: intuition is borne from experience, and our own personal experience of the Universe is entirely classical. Our Universe is made up of particles at a fundamental phenomena, and collections of particles can compress, rarify, and oscillate in ways that appear wave-like.

But down in the quantum realm of atoms, photons, and individual electrons, wave-like behavior is just as fundamental as particle-like behavior, with only the conditions of the experiment, measurement, or interaction determining what we observe. At very high energies, experiments can reveal that particle-like behavior we're so familiar with. But under normal circumstances, like the ones we consistently experience in our own bodies, even an individual electron is spread out over an entire atom or molecule.

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... (MORE - details)
