Could Life Survive Without a Star?

The video explores the concept of rogue planets, which are planets not orbiting a star, and their potential to support life. It discusses how life on Earth can exist without sunlight, suggesting that life could emerge in dark environments like subterranean pockets or hydrothermal vents. The importance of liquid water is highlighted, though it's noted that life might not necessarily require it. Various heating mechanisms, such as core heat and tidal heating, are examined as ways rogue planets could maintain temperatures suitable for life. While complex life is unlikely, microorganisms might thrive in these conditions.

What role does liquid water play in the potential for life on rogue planets?

Explain the concept of tidal heating and its relevance to rogue planets.

What limitations exist regarding the complexity of life on rogue planets?
