‏Stephen Hawking Warns: Humanity May Have Less 
Than 600 Years to Leave Earth

If humanity doesn't become a truly spacefaring species in the next five centuries or so, we may well go extinct, Stephen Hawking said, according to media reports.
During a video presentation Sunday (Nov. 5) at the Tencent Web Summit in Beijing, the famed cosmologist warned that the ever-rising human population, and its mounting energy needs, could render Earth uninhabitable by the year 2600, according to the British newspaper The Sun.
‏Hawking therefore advised that we get our act together and "boldly go where no one has gone before," The Sun reported.
‏During his talk, Hawking also highlighted the exploration potential of Breakthrough Starshot, a $100 million project that aims to develop tiny, uncrewed, sail-equipped probes that will be accelerated to 20 percent the speed of light by powerful lasers.
‏Such nanocraft could get to Mars in less than an hour and theoretically fly by the closest exoplanet to Earth — the possibly habitable Proxima b, which lies about 4.2 light-years from us — after a space journey of just 20 years, Hawking and other Starshot team members have said.
‏"Maybe if all goes well, sometime a little after the middle of the century, we'll have our first picture of another planet that may be life-bearing orbiting the nearest star," Breakthrough StarshotExecutive Director Pete Worden, the former head of NASA's Ames Research Center, said at the summit in Beijing, according to The Sun.
