Stephen Hawking's Favorite Places is a new documentary available on the CuriosityStream video service that, in 26 minutes, shows us our own Hawking describing the cosmos on board an imaginary spaceship called SS Hawking, with which it makes five different stops.
Hawking observes the Big Bang that created the Universe, visits a monstrous black hole in the center of the Milky Way, travels to Gliese 832 c and orbits Saturn. Finally, the SS Hawking comes to the place that the scientist considers his home: the California Institute of Technology (Caltech). However, in this documentary warn us again of the risks of finding intelligent extraterrester life.
According to Hawking, Humanity should be cautious in the search for contact with alien civilizations. Something of what he already warned us in 2010, when he declared that intelligent aliens could be looters looking for sources of resources to exploit in the cosmos:
One day, we could receive a signal from a planet in those circumstances, "Hawking says in the documentary, referring to the potentially habitable world known as Gliese 832c." But we should be cautious in responding. Finding an advanced civilization could be like when the Native Americans met Columbus. That didn't work out well.
