Yep, space is just IMMENSE, and this reminds me of the reason why I like exploration in Elite Dangerous so much - a very beautifully rendered space game. With a highly realistic space model, it even gets darker as you reach the galaxy edges.
Apologies in advance to the real scientists here for my naivete, however: As we know there's billions of galaxies too - it makes me feel like everything is just a big Mandelbrot set. We've picked galaxies on the top end, and atoms on the other, but is that really where it ends, or is it just the edges of our ability to perceive?
To my amateurish understanding, it does go smaller than atoms, with subatomic particles like protons which themselves are made of quarks. Beyond that string theorists would say that there would be strings and that's it. Others might say some kind of quantum foam.
Going up, galaxies make up groups which combine into superclusters that form the cosmic web of the observable universe.
So for all intents and purposes, we can essentially say the universe and the various scales are infinite because it may as well be for humans.
