A Better Way to Study Earth, and Lessons from Jellyfish Galaxies

The video explores two main topics: the study of Earth's interior using neutrinos and the investigation of jellyfish galaxies. Neutrinos, elusive particles, can provide insights into Earth's internal structure by analyzing their flavor changes as they pass through different densities. A new detector, Dune, will enable these measurements by 2027. The second topic covers jellyfish galaxies, which have active supermassive black holes. These galaxies interact with the intracluster medium (ICM), causing gas to trail behind them like jellyfish tentacles. The study reveals that the ICM likely activates the black holes, offering insights into galaxy dynamics.
