Cool video. I hadn’t thought of that, but of course it makes sense!

Unrelated question for anyone out there: I’m using the Liftoff app, and this link only opens in the Liftoff app… Is there a way to easily get it to open in the YouTube app instead? Making the video full screen doesn’t quite work as it is.

This is another one of those videos that spends a lot of time in lateral subjects without diving deeper in the main subject. I thought the idea that earth radiates energy made by biological processes fairly significant, and a far more interesting thought experiment to meditate on (Can we find aliens by looking at the thermal signature of exoplanets? Is there a methodology we can use to measure the efficiency of life?). Instead, it covers extremely basic principles of thermodynamics and heat pumps, which has been done to death in other videos.
