What is the "shape" of the universe?

This may help. Her videos delve into some of the very questions you're asking. She has a lot of videos out, so you might need to search through them.

Thanks for this question - I've always been interested in the sheer size of the universe. And of course with that comes the question of shape. I'm also into those "map of the universe" posters, which usually show it in a large sphere. I also had the question of marking the location of other galaxies relative to the earth in a 360 sphere scale.

And we know when you map out the galaxies, they create a lattice structure with voids in-between.

The solar system is not "flat" per say, but most of the structures lie in a "flat" plane, but that is due to gravity and the relationship of the gravity created by the sun, correct?

I consider this article on Wikipedia about the "particle horizon" to be very informative:

https://en.wikipedia.org/wiki/Particle_horizon


Specially where it reads "The particle horizon recedes constantly as time passes and the conformal time grows. As such, the observed size of the universe always increases."

I would imagine there are really powerful computers using AI to expand on the theories re shape, size and other characteristics of the universe.
