According to renowned British scientist Stephen Hawking, aliens could be more interested in exploiting our natural resources than sharing their technology with us.
If intelligent alien life forms do exist out in the vastness of the space, they might not be the friendly cosmic neighbors the people of Earth are looking for, famed British scientist Stephen Hawking says in a new television series chronicling his work to explore the secrets of the universe.
An advanced spacefaring extraterrestrial civilization could end up wandering the universe in enormous spaceships on the prowl for vital materials after consuming the natural resources of their own world, Hawking explains in an episode of the show "Into the Universe with Stephen Hawking," which premiered Sunday on the Discovery Channel.
"Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they could reach," Hawking said. "If so, it makes sense for them to exploit each new planet for material to build more spaceships so they could move on. Who knows what the limits would be?"
In the four-part series, Hawking explores topics such as aliens, time travel, and the origin of the universe.
In one episode, he suggests an alien species could be capable of harnessing solar energy to open up a wormhole in space to travel to distant parts of the universe.
