Similarities across different scales of the universe.

We see protons and neutrons in the centre of atoms. (Small scale)
We are seeing 2 black holes on average per galaxy. (Large scale)

We see attractive and repulsive forces on the small scale.
On the large scale we see dark matter as an attractive force and dark energy as a repulsive force.

Yes.

We see atoms as fuzzy objects and galaxies as fuzzy objects.

Different numbers of planets orbit stars and different numbers of elecrons orbit the nucleus of an atom.

We see a layered structure with atoms on the small scale and on the larger scale we see a layered structure with planets and stars.

Space time and particles on the small scale, space time and particles on the larger scale.

Fractals on the small scale and on the larger scale.

Electromagnetic energy on the small scale and on the large scale electromagnetic energy connecting stars to planets and connecting galaxy to galaxy.
