Next part: https://youtu.be/hFMaT9oRbs4 Patreon supporters see early views of new videos: https://www.patreon.com/3blue1brown Artwork by Kurt Bruns Thanks to Paul Dancstep for several animations, such as the powers of 10 zoom out and the simulations of shadows on the moon. Terry has kindly cataloged many of the added nuances, including a few corrections, in this post: https://terrytao.wordpress.com/2025/02/13/cosmic-distance-ladder-video-with-grant-sanderson-3blue1brown-commentary-and-corrections/ As an additional one, the portrait shown for Kepler, despite being somewhat widespread, actually turns out not to be Kepler. See this article by Václav Pavlík https://ui.adsabs.harvard.edu/abs/2021PhT....74i..10S/abstract Also, although the Earth is about 4 times as wide as the Moon, as it happens, you would not see this with the lunar eclipse composites, since the umbra of Earth's shadow from the sun is sufficiently smaller than the Earth out where the Moon is. Moon composite shot by Reddit user _wanderloots: https://www.reddit.com/r/astrophotography/comments/yil0tu/partial_lunar_eclipse_composite/ https://youtube.com/@Wanderloots Thanks to Tanya Klowden for helpful conversations about the history of the distance ladder.
