Cool Worlds Lab has another great video out, this time discussing the Rare Earth Hypothesis. This hypothesis assumes that a multitude of factors are necessary for life to develop in the universe, and the program goes deeper into a few of these factors, including the need for:
- A magnetosphere;
- Plate tectonics;
- A large moon;
- Impacts from asteroids and comets; and
- A Jupiter-sized planet.
The program challenges some of these factors and also highlights the need for a more open understanding of the origins of life beyond our current understanding. Basically, the conditional probably of the Drake Equation or even the modified Drake Equation unnecessarily leads one down a very narrow path.
It’s an eye-opening review of the evidence and worth watching. Check it out.
