在科幻电影《全面回忆》中,地心隧道列车出现在银幕上,这或许还是电影史上的第一次。其实地心隧道列车并不是什么新奇的想法,早在17世纪,英国科学家胡克就写信给牛顿,提出过这个设想,随后进入研究阶段,不过后来两人因为知识产权争议变成了宿敌,见面就架,所以这项研究也就不了了之。到了20世纪60年代,美国科学家保罗·库珀又发表论文,重新探讨了地心隧道列车作为未来交通工具的可能性。那么,人类能否在不久的将来建造出地心隧道列车呢?实现此设想会遇到哪些技术难题?我们可以从以下两个角度来探讨这个问题。
In the science fiction movie “Total Recall,” the geocentric tunnel trains appear on the screen, perhaps for the first time in movie history. In fact, the geocentric tunnel train is not a novel idea. As early as the 17th century, the British scientist Hook wrote a letter to Newton proposed the idea and then entered the research stage, but later the two became rivals because of intellectual property disputes. Meet on the shelf, so this study will be gone. By the 1960s, the American scientist Paul Cooper published another paper to revisit the possibility of a geocentric tunnel train as a future means of transport. So, can mankind build a geocenter and tunnel train in the near future? What are the technical problems to realize this idea? We can explore this issue from the following two perspectives.
