Last year, Stephen Hawking's "extinction of mankind" theory suggested that we may need to leave Earth within the next 1,000 years before life on our planet ceases to exist. But a new documentary suggests that the British physicist has an even more dire extinction prediction these days, one that points to humanity possibly lasting only another hundred years, and one that may require a greater sense of urgency as far as humans possibly colonizing Mars is concerned.
Late last year, Stephen Hawking's timeline for the extinction of mankind was established at about 1,000 years, as he spoke at a lecture about the need to colonize other planets within that time before Earth becomes uninhabitable. According to Science Alert, Hawking cited "powerful autonomous weapons" as one of the biggest threats against mankind, which added to previous comments that suggested artificial intelligence may be "either the best, or the worst" thing to happen to our species
At the time Hawking made those remarks, he had added that living in Mars might not be a plausible idea until another century from now. But teasers for his upcoming documentary suggest that mankind might not have that luxury of time anymore.
