环亚国际app-This Quantum Theory Predicts That The Future Might Be Influencing The Past根据这个量子理论的预测,未来有可能正在影响着过去One of the weirder aspects of quantum mechanics could be explained by an equally weird idea – that causation can run backwards in time as well as forwards.量子力学中最怪异的部分,有可能可以用一个某种程度怪异的点子来说明——因果关系可以逆时间而动。A pair of physicists from the US and Canada took a closer look at some basic assumptions in quantum theory and decided unless we discovered time necessarily ran one way, measurements made to a particle could echo back in time as well as forward.美国和加拿大的一些物理学家细心研究了量子理论中的一些基本假设,然后意识到:除非我们能寻找“时间不能单向前进”的确凿证据,否则我们对粒子的测量只不过不光能顺着时间方向起起到,某种程度也有可能可以逆着时间方向起起到。

We all know quantum mechanics is weird. And part of that weirdness comes down to the fact that at a fundamental level, particles dont act like solid billiard balls rolling down a table, but rather like a blurry cloud of possibilities shifting around the room.我们都告诉量子力学很怪异。而我们实在它怪异的其中一个原因就是:在一个基础的层面上,粒子并不看起来桌上的台球那般有明确的形状,它们更加看起来一团在空间中四处游移的云雾,而构成这个云雾的东西是“可能性”。

This blurry cloud comes into sharp focus when we try to measure particles.而当我们要测量一个粒子的时候,这团云雾就不会变为一个特定的形态。A physicist by the name of Huw Price claimed back in 2012 that if the strange probabilities behind quantum states reflect something real, and if nothing restricts time to one direction, the black ball in that cloudag8亚洲国际 of maybes could theoretically roll out of the pocket and knock the white ball.一位叫毕·普莱斯的物理学家在2012年的时候声称:如果量子态背后这种怪异的概率现象体现了什么世界的真凶,而同时又没什么东西容许时间不能单向移动,那么从理论上谈,球袋里的黑球就可以衰退回去敲击桌上的白球(时间可反败为胜)。

Critics object that there is complete time-symmetry in classical physics, and yet no apparent retrocausality. Why should the quantum world be any different? Price wrote.普莱斯写出到:“批评者赞成说道:在经典物理学里,时间是极致平面的,而且也没看见偏移的因果关系。为什么量子世界就可以不一样呢?John Stewart Bell said that the weird things that happen in quantum mechanics cant ever be explained by actions taking place nearby. Its as if nothing is causing the multitude of billiard balls to take such varied paths. At a fundamental level, the Universe is random.(知名的物理学家)约翰·斯图尔特·贝尔曾说道:量子力学里的各种怪异现象,都无法用它周围再次发生的事情来说明;就样子没什么东西在左右这些台球的行动一样;在一个基础的层面上,宇宙是随机的。

But what about actions taking place somewhere else... or somewhen else?但是,不会会是某些别处的事情,或别的什么时候的事情,在起起到呢?Needless to say, the idea of retrocausality is a fringe idea.不用说,偏移因果关系依旧是个边缘点子。_环亚国际app。
