New Model Solves Grandfather Paradox

Goldfishy writes "If you went back in time and met your teenage parents, you could not split them up and prevent your birth - even if you wanted to, a new quantum model has stated. Researchers speculate that time travel can occur within a kind of feedback loop where backwards movement is possible, but only in a way that is 'complementary' to the present. In theory, you could go back in time and meet your infant father but you could not kill him." From the article: "Quantum behaviour is governed by probabilities. Before something has actually been observed, there are a number of possibilities regarding its state. But once its state has been measured those possibilities shrink to one - uncertainty is eliminated."

“如果你回到过去遇见你年少的父母,你不能拆散他们来阻止你的出生——即使你想要,一个新的量子模型的研究结果。研究员推测时空旅行回到过去是可能的,但是至今只是一种方式‘补充’。理论上,你能回到过去遇见你婴儿般大的父亲,但是你不能杀他。”原文:“量子力学的表现基于概率。在某些事实际观测之前,关于它的状态可能性有很多。一旦一件事被观测到,其概率就为1——不确定性就不存在了。”
