Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
Douglas Adams,Β [The Hitchhikerβs Guide to the Galaxy]
Also the solution to the Fermi Paradox.
with how big space is. does the map determine if the location is where the thing currently are or just everything we can see at this time.
the latter. the map looks different further away from the center of the circle because further away = earlier time. if they attempted to compensate for how things far away have changed since the light was emitted, the map would look uniform.
What do those colored rings mean?

@expatriado@lemmy.world do you happen to know what the less dense ring in the outer part is?
My not very confident guess is that it's just to label what kind of galaxies are observed by the instrument at that range. Really not sure about the less dense ring in the outer part though.
Because of relativity, there is no difference.
Very insane that we as a species (very very very small) were able to survey the (observable) universe and its structure (very very very big, far bigger than the biggest big we can big of) to such an accurate detail.
Even more insane that eventually, even if life still exists, you won't be able to see ANYTHING outside your local galaxy, because all the clusters will have merged together, and there will be so much space in between that even light can't get between the galaxies anymore.
