What If Earth Became a Rogue Planet?

The video explores the dynamic nature of stars in the galaxy, highlighting their rapid movement and potential threats to Earth. It delves into the role of gravity in shaping cosmic interactions and the solar system's stability. The video discusses the risks posed by close stellar encounters, such as Glea 710, which could disrupt the solar system and lead to catastrophic events on Earth. It also considers the possibility of Earth becoming a rogue planet and the survival strategies humanity might employ. The video concludes with stellar experiments and emphasizes the importance of understanding astrophysical processes.
