The Euclid telescope, just launched today, will be able to observe galaxies out to 10 billion light-years. Here’s the largest map I could find (1 billion light years) that includes the Milky Way, Laniakea, the Shapley supercluster, the Perseus–Pisces supercluster, and the South Pole Wall.

Deep Space is neat, but the thing that really gives me a fun sense of philosophical vertigo is Deep Time. My favourite exploration of that is the video Timelapse of the Future, which shows time passing at a rate that doubles every five seconds (ie, time is passing at a rate of one year per second for five seconds, then two years per second for the next five, then four years per second, etc.)
The last stars in the universe go dark at around the 5-minute mark. The video as a whole is about 30 minutes long.
If you want a more uplifting view of that future, Isaac Arthur’s Civilizations at the End of Time playlist goes into great detail about how intelligent life can persist throughout that entire duration and still have a good time.
And of course, there’s the famous Isaac Asimov short story about this, “The Last Question”.
I admittedly have not read a lot of Asimov but The Last Question is one of the few stories I’ve read in full (it helps that it’s a short story) and I absolutely loved it!
That was an amazing video! Thanks for sharing.
Wow I just so happened to jump back on here and check out the Timelapse video right as my THC tablet kicked in. 10/10 highly recommend the experience, no pun intended.
