Size comparison (From the smallest known object to the biggest measured object)
we're going to look at the smallest known object ever found which is a Preon to the observable universe which is the biggest measured object. Sorry, to all my viewers who were waiting for my post for so long, but believe me I was working on a really, long post and here it is now in front of you. Preon 10 ^ -18 metres In particle physics, preons are point particles, conceived of as sub-components of quarks and leptons. The word was coined by Jogesh Pati and Abdus Salam, in 1974. Quark They are considered point like entities with zero size A quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. All commonly observable matter is composed of up quarks, down quarks and elect...
