Imagine the following experiment conducted by an extraterrestrial intelligence:
An array of 20 parallel existing universes, each of them containing our human civilization on planet Earth.
In this array, Universe 1 contains the most stupid human beings. Universe 20 contains the most intelligent human beings.
The extraterrestrial researchers want to find out how intelligent human beings must at least be in order not to become extinct by fossil driven #ClimateChange.
We reside in Universe 8.
