Random thought: Assuming standard physics, with big bang & expanding universe... Where the further you look out, the farther back in time you see..🤔 and the closer all the galaxies would be to one another..🤔
How can the bubble of space-time that comprises your visible universe, be contained by an area smaller than your visible universe?
Look in any direction, and find a landmark (skymark? spacemark? 😅). Then look perpendicularly and find another. Would they be both visible in both directions?🤷🏻♂️

Outer Space is not a perfect vacuum
Think of it like a gas or plasma with a lower density than air near the surface of the earth but a higher density than zero
When light is red shifted it is assumed that an object is traveling away
Because all light coming to earth is red shifted relative to the expected emmission pattern it is incorrectly assumed the Universe is expanding
But as light travels through a medium it can be red shifted
The Universe is not expanding
Big bang is wrong
