https://www.pbs.org/video/how-much-of-the-universe-can-humanity-ever-see-bboivw/ https://www.pbs.org/video/how-much-of-the-universe-can-human... does a good job explaining the theoretical limits of how much universe humans will be able to observe. Based on today a knowledge of the universe, even if humans colonize the entire universe, you would eventually lose contact with humans in certain areas and therefore their knowledge. I felt like humans were doomed after watching it, despite the vast scales discussed.
