New Clues to the Structure of the Universe

The video discusses the New Horizons mission's findings on Pluto, focusing on the formation of Sputnik Planitia and its impact on Pluto's rotation through true polar wander. It also covers the discovery of the brightest fast radio burst, FRB 150807, and its potential to reveal the universe's structure. The video concludes with a call to support SciShow on Patreon.
