Some of the biggest names in science and technology have called for the colonization of Mars, including physicist Stephen Hawking and SpaceX CEO Elon Musk. They say that populating other planets would help ensure our species’ survival should Earth be rendered uninhabitable by some disaster.
“The future of humanity is fundamentally going to bifurcate along one of two directions,” Musk said last year. “Either we’re going to become a multiplanet species and a spacefaring civilization, or we’re going to be stuck on one planet until some eventual extinction event.”
That sounds about right.
