If you really want to be messed up, absolutely nothing is where we think it is because gravitational lensing affects the light of every object in the universe, while we observe. The further away it is, the more light is warped by the masses along the path, and we can’t know what those many masses are or where they are either.
Our observability of the universe is a guessing game as large as the universe, and there is no conceivable model to assess it all and the interrelations between…everything.

Now this is something that I knew absolutely nothing about, but I feel like it should have occurred to me with what I did know.
Thank you.
