近日，英国剑桥大学存在风险研究中心(CESR)公布了人类灭绝的10种可能，并对它们的风险等级进行了排序。CESR认为美国总统特朗普也可能引发世界末日，并且认为这种可能性超过了行星撞地球、气候变化以及机器人杀手等威胁。一起来看看世界末日究竟可能会以何种方式到来吧！

⒈Artificial Intelligence 人工智能

Humanity faces an uncertain future as technology learns to think for itself and adapt to its environment. Experts predict①that machines will attain②90 percent of human-level intelligence by 2075．

由于科技开始学习自我思考并适应环境，人类正面临着一个不确定的未来。专家预言，到2075年，机器的智力水平将达到人类的90%。

⒉Bio-hacking 生物黑客

Superbugs capable of everything from curing diseases to mopping up③pollution could one day become reality, through synthetic④biology．

从治疗疾病到清除污染，合成生物学有朝一日会让无所不能的超级细菌变成现实。

⒊Killer robots 机器人杀手

Fully autonomous⑤weapons, also known as "killer robots", are quickly moving：from the coverage of science fiction toward reality.Removing humans from the targeting decision would create a dangerous world, with machines making life-and-death determinations outside of human control．

全自动武器也被称为“机器人杀手”，它正迅速从科幻小说走向现实世界。当机器在作出生死决定时不受人类控制，在决定目标时将人类排除在外，世界将变得非常危险。

⒋Nuclear War核战争

There are now more than 15,000 nuclear weapons on this planet, but to pull Earth into a devastating⑥nuclear winter, all it would take is the detonation⑦of l00．

目前，地球上存在的核武器超过1 5000枚，但是只需要引爆1 00枚核武器就可以让地球进入灾难性的核冬天。

⒌Climate change 气候变化

Scientists warn of a tipping point-a temperature beyond which the problem can no longer be dialled back. If we reach this point, a runaway⑧greenhouse effect would cause temperatures to rise to several hundred degrees Celsius, boiling the oceans and making life on Earth impossible．

科学家们提醒，气温超过某个临界点之后，问题将会到无法挽回的地步。如果气温达到了这个临界点，那么失控的温室效应将会使气温飙升到几百摄氏度，让海水沸腾，地球上将无法生存。

⒍Asteroid impact 小行星撞击

With energy greater than 10 million Hiroshima bombs, the impact⑨shock would fl atten everything within a 186, mile(300km) radius⑩However, the CESR rate this as a low risk priority.

小行星撞击的能量比1 000万枚投放在广岛的原子弹还要强，其带来的冲击能把方圆300公里的土地都夷为平地。然而，CESR认为这种情况的可能性较低。

⒎Simulated world 虚拟世界

While still largely the preserve of science fiction，the idea that the world we experience as"real" is actually just a simulationis still given serious thought by sci entists, philosophers, and even businesses．

科学家、哲学家、甚至连商界都在认真思考这样一种观点，即人类认为的“真实”世界实际上是虚拟的，不过这种观点基本上仍然停留在科幻小说之中。……
