pets2考试阅读文章精选段落06
You cannot change the laws of physics …… but could physics actually enable us to travel through time? It might sound crazy, but according to Einstein's theories, there's no logical reason why time travel isn't possible and there are now scientists looking into it as a serious scientific proposal, at least at a theoretical level.
