Stephen Hawking is again warning about announcing our presence to any alien civilizations that might be out there, especially those that could be more technologically advanced.
In his new half-hour program "Stephen Hawking's Favorite Places" on science-themed subscription service CuriosityStream, the world's most famous theoretical physicist flies by the potentially habitable exoplanet Gliese 832c in a CGI spaceship as part of his hypothetical dream itinerary for a tour of the universe.
It's a sentiment Hawking has expressed before, but not everyone agrees. Ultimately, though, the argument over whether to reach out to E.T. could be a moot point, if, as some believe, aliens have already been in touch and visiting Earth for centuries.
