Scientists calculated how much energy plants can extract from the light of different stars. It turns out: photosynthesis around red dwarfs dies out, like a campfire without wood. This means complex life is better sought around Sun-like stars.

🎯 The upper theoretical limit for oxygen production on Earth is thousands of times higher than what plants actually produce.
