Cosmic Catastrophes and Planetary Dynamics

The video explores the history of catastrophic events in our solar system, focusing on Jupiter's rings and the impact of the Shoemaker-Levy 9 comet. It discusses recent impacts on Jupiter and their implications, highlighting the protective role Jupiter plays for Earth. The video also examines potential future threats from orbital chaos involving Mercury and Mars, as well as the possibility of galactic collisions with the Andromeda galaxy.
