This zoomable picture of the Andromeda galaxy has insane detail. It really impressed me with the crazy amount of stars visible once you fully zoom in. And that is just a small section of one galaxy! Made me realise how unfathomable the total amount of stars in the universe really is
Now imagine there are galaxies of galaxies containing as many galaxies as there are stars in the galaxy.
Keep in mind the astonishing distances between galaxies.
Remember the original astonishing distance between stars that is nothing compared to distance between galaxies that is again nothing compared to the distance between galaxy clusters.
Now, multiverse theory.
Do you mean galaxy groups and clusters? As far as I’m aware, there is no such thing as a galaxy of galaxies.
It was purposefully typed in this way to hopefully better convey the sense of scale and achieve the impossible task of imagining such monstrous sizes. I wanted the reader to feel certain emotion.
