For alien hunters, patience is a virtue. According to famed theoretical physicist Stephen Hawking, it's unlikely that scientists will discover intelligent life in the next two decades.
Hawking, along with Russian venture capitalist and physicist Yuri Milner and a group of scientists, discussed how Starshot would send "a multitude of tiny, wafer-sized spaceships," traveling at 20% of the speed of light, to Alpha Centauri within 20 years.
In the spaceships' one-hour flyby, they can take close-up photos of Alpha Centauri, probe "space dust molecules" and measure magnetic fields. However, in that same 20-year span, Hawking pointed out, locating intelligent life isn't worth getting our hopes up.
But that doesn't mean it's not out there. Hawking said that Kepler mission discoveries "suggest that there are billions of habitable planets in our galaxy alone. There are at least a hundred billion galaxies in the visible universe, so it seems likely that there are others out there."
"Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach," Hawking said, according to Live Science.
At least we can take solace in knowing that the extraterrestrials will likely be nothing like Donald Trump.
