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 electrons.
Proton
10 ^ -15 metres
A proton is a subatomic particle, symbol p or p⁺ , with a positive
electric charge of +1e elementary charge and a mass slightly less than
that of a neutron. Protons and neutrons, each with masses of approximately
one atomic mass unit, are jointly referred to as "nucleons".
0.00000000011 m

this volume galaxies and associated objects are essentially frozen in
their present day configurations.
Observable universe
880000000000000000000000000 m diameter
The observable universe is a ball-shaped region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present
time, because the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion. There may be 2 trillion galaxies in the observable universe, although that number has recently been estimated at only several
hundred billion based on new data from New Horizons. Assuming the universe is isotropic, the distance to the edge of the observable universe is
roughly the same in every direction. That is, the observable universe has
a spherical volume (a ball) centered on the observer. Every location in the universe has its own
observable universe, which may or may not overlap with the one centered on
Earth.
