Renowned physicist Stephen Hawking has issued yet another warning for Earth and this time, he says we have less than 600 years before the Earth turns into a sizzling fireball.知名物理学家斯蒂芬·霍金日前收到了对地球的又一个警告，这一次，他声称在地球变为一个散发出的火球之前，我们只有将近600年的时间了。Hawking says that if we dont leave Earth soon, overpopulation will increase energy consumption and pretty much kill us all.霍金回应，如果我们不尽早离开了地球，过多的人口不会减少能源消耗，很有可能会使人类全部覆灭。
But Hawking has a plan. Speaking at the Tencent WE Summit in Beijing, Hawking appealed to investors to back his plans to travel to Alpha Centauri. At around 4 light-years away, its the closest star system to our sun.不过，霍金有一个方案。在北京举办的腾讯WE峰会上，霍金敦促投资者反对他的计划--前往半人马座阿尔法星系。在约四光年外，它是离太阳系最近的恒星系统。
The venture is called Breakthrough Starshot and it would use a tiny spacecraft that travels at the speed of light.该冒险计划被称作“突破摄星”，将用于需要以光速前进的小型飞机。Such a system could reach Mars in less than an hour, or reach Pluto in days, pass Voyager in under a week and reach Alpha Centauri in just over 20 years.“这样的一个系统可以在一小时内抵达火星，或者在数天内抵达冥王星，在一周内可多达“旅行者”号探测器，并在20多年内抵达半人马座阿尔法星系。”Maybe if all goes well, sometime a little after the middle of the century, well have our first picture of another planet that may be life-bearing orbiting the nearest star, Pete Worden, the former head at NASAs AMES Research Center and Starshot Breakthrough director, said at the summit.前NASA艾姆斯研究中心主任皮特·沃登在WE峰会上回应：“如果顺利了，在本世纪中叶后的某个时间，我们就有可能看见另一个环绕着半人马座阿尔法星系运营的、有生命的星球的第一张照片。
