Thinking about the Universe being shaped like a huge ball , & given that we are not in the center because there is no center : When Scientists (& Astronomers) look out in various Directions , though various tools , is the Distance Measurement almost same for the farthest Entities ?
Let us say , Earth (& Solar System) is at the Crossing in the Purple Area, which is the Partially known Universe.
The Inner Circle is the "Edge" of the Partially Known Universe.
The White Area is the Knowable Universe , when newer tools are available in the future.
The Outer Grey Area is the Unknowable Void beyond the Known Universe.
We have Entities (Star Systems , galaxies , black holes , Inter-galactic gases) on the Edge of the Partially Known Universe.
Looking at Entity 1 : We currently measure Distance D.
Looking at Entity 2 : Do we measure Distance D (APPROX) ?
Looking at Entity 3 : Do we measure Distance D (APPROX) ?
Looking at Entity 4 : Do we measure Distance D (APPROX) ?
I am asking about all 3 Dimensional Directions.
