This simulation made me allmost cry, I mean, try to imagine yourself in an orbital colony (or space station), observing the end of life on earth, wouldn’t you cry? Even if all of your friends and family are with you.. I mean, alli life on earth, creatures, plants, habitats..
In any case, turning off the sentimental mode, there are lots of people studing this field, and ls widely believed that impacts similar to the simulation have happened on earth history.
