Responding to aliens is a really, really bad idea - Stephen Hawking
Stephen Hawking has advised us earthlings to be extremely wary about answering any signals from aliens when they eventually come calling.
Hawking made the comments during his new online show ‘Stephen Hawking’s Favourite Places’. In the programme, the renowned astrophysicist ‘visits’ the potentially habitable Gliese 832c, a planet located some 16 light-years from Earth.
“As I grow older I am more convinced than ever that we are not alone,” says Hawking.
Hawking believes there could very well be life on Gliese, but imagines a meeting between the two civilizations as something that would resemble Christopher Columbus meeting Native Americans, saying, “that didn't turn out so well.”
"One day we might receive a signal from a planet like this, but we should be wary of answering back,” he cautions.
#ViaGizmodo.com The nearest #Earthlikeplanet is only #16lightyears away from us. It has a mass that is more than five times the mass of the Earth and it orbits a red dwarf star that has half the mass and radius of our sun. But the most important thing about the #Gliese832c, as astronomers at the #UniversityofNewSouthWales are calling it, is that it receives the same average energy as the Earth does from the sun. This makes it fall in a "#habitablezone" — the just-right range of distances that could allow liquid water to exist on a world's surface, according to #Spacedotcom. "It's just a stone's throw from Earth in the cosmic scheme of things," writes Space.com's Mike Wall. This makes the Gliese 832c one of the top three most Earth-like planets ever discovered and the closest one to Earth of all three, says #AbelMendezTorres on the #PlanetaryHabitabilityLab's blog.

In the program, Hawking references ‘The Breakthrough Listening Project’, a 10-year $100 million initiative, which has Hawking on board, and funded by Russian Billionaire Yuri Milner.
“After a lifetime of wondering, I am helping to lead a new global effort to find out,” Hawking said of the initiative.
The project is the biggest alien-hunting exercise ever undertaken and plans on using the world’s most sensitive radio telescopes to listen in on 10 times the amount of sky than similar enterprises have achieved in the past.
But don’t start packing your bags just yet. On Gilese, a year lasts only 36 days, the atmosphere is thick with fog “or worse”, and one side is constantly facing its sun.
