- I read the article but didn't watch the videos yet, but I'm curious as to what would be needed to make this a 3D map. That is, I'm assuming this 2D map records the position of all of these objects in the sky, but not the distance from Earth. But I thought that calculating the distance of objects is relatively straightforward, e.g. you hear all the time "Galaxy X is 2 billion lightyears away" or whatever. Would it just be really computationally expensive to calculate the distance to all of the 4 billion objects identified in the map?

- That's impressive. Though I think there's too much space on this plane. I'm wondering whether it is actually a 2D view since it obviously isn't planar.
To paraphrase Samuel L Jackson - "I have had it with this m'f'ing space on a plane! Everybody strap in I'm about to open some f'in' windows."
Proceeds to crank open an array of telescopes to get another 3D perspective of a 4D universe so we can project it onto our 2D viewing devices as if that were reality.

by flockonus - I've got some crazy feelings browsing this.
Are there any particularily detailed areas? But maybe the humbling reality is just: The closer we look, the more galaxies appear where we thought was black void…

- Researchers expect it will remain the most comprehensive 2D map of our universe for years to come.
Most likely. I doubt there is going to be any serious investment in astronomy over the next decade given economic headwinds and a deteriorating strategic situation. The big money will be going into defense and economic sovereignty and building/launching new high powered telescopes will not be a priority. Optical/sensor advances will be prioritized for earth observation (commercial, military, or weather/climate) and it maybe that we're in an era of diminishing technological returns already. I do expect a lot of analytical advances thanks to the combination of open datasets and AI, although it seems more likely that most of these will be in stamp collecting - interesting astronomical facts for people who are already interested in astronomy. Hard to guess if we will see challenges to prevailing cosmological theories.
