- dredmorbius 1y agoThere are a number of likely mass-extinction / life-terminating events which will occur within the next billion or so years, either deterministically or probablisticaly (e.g., increased solar insolation and plate tectonics are deterministic, massive gamma-ray burst or killer asteroid are probabalistic), of which supercontinent-formation is only one. Wikipedia's "Timeline of the Far Future" lists several: <https://en.wikipedia.org/wiki/Timeline_of_the_far_future https://en.wikipedia.org/wiki/Timeline_of_the_far_future> We likely exist in the late afternoon if not evening of Earth's habitable period.
