Veritasium explains why so much of the matter around us is formed out of empty space and how much of this empty space is, in fact, filled with energy. In short words, there is no such thing like an absolute void. There is the Cosmic background radiation and also the energies at the levels of gluons, where quantum chromodynamics explain why there is no such thing as a pure void. Gluons help quarks stick together to form protons and neutrons.
Quantum physics is way over my head, but it is good to know that the reality we live in might be really strange and way different that we would think it is. Honestly, I do no understand why I didn’t chose to learn physics in the first place.
