Discussion is revisiting one of astronomy's great reversals: the once-standard belief in a static universe gave way after Edwin Hubble's observations showed galaxies receding from one another, revealing cosmic expansion. Commenters are using the story to explore how scientific certainties change over time and which unsolved mysteries, from dark energy to the universe's ultimate fate, still challenge cosmology today.
- 2New episode explores Edwin Hubble's 1925 galaxy discoveryโNeue Folge! Um was handelt es sich bei den verwaschenen Spiralnebeln am Himmel? 1925 beweist Edwin Hubble: Es sind Galax
A new episode of an astronomy series asks what the faint spiral nebulae in the night sky actually are, recounting how Edwin Hubble proved in 1925 that they are galaxies beyond the Milky Way, even though Hubble himself avoided the word 'galaxy'. The episode, presented by Franzi, explores an universe full of 'island worlds' and invites listeners to reconsider how humanity learned the true scale of the cosmos.
