Cosmology & astrophysics Videos Recommended on Hacker News (108)
Cosmology & astrophysics is one of the 150 topics Hacker News readers organize their video recommendations around. These 108 videos each earned real recommendations in real HN threads between 2009 and 2026 — 287 recommendations in total — and they're ranked by how many separate months the community kept coming back to them, not by view count.
Cosmology and astrophysics: black holes, dark matter, dark energy, Big Bang, galaxies, stars, gravitational waves, exoplanets, the observable universe, Sabine Hossenfelder, Kurzgesagt.
Why HN keeps sending people here — on TIMELAPSE OF THE FUTURE: A Journey to the End of Time (4K): “does a great job with visuals and voiceovers about what will happen over the next trillions x trillions of years” — an HN commenter, 2023.
