首先,读这三个非常相关的问题和答案://www.hoelymoley.com/q/16730/725 //www.hoelymoley.com/q/246/725 //www.hoelymoley.com/q/2468/725 - - - - - - - - - - - >可以发送探测地球深处吗?#没有。# #原因如下:首先,有一个非常常见的误解,下面有一些岩浆海洋地壳。不,没有。地幔是坚硬的岩石。有非常小的和局部的地方你有融化,这就是你有火山(如果它到达水面——通常它不会)。其次,即使你去火山放探针,没有简单的管,下降。火山“管道”系统更像是一个迷宫和分岔,弯曲,缺陷,所有。不仅如此,你会流。你可能看到过喷发熔岩流的视频([1][1],[2][2])。 These things are massive and fast. Your probe will have to go against the flow in that thing. It will be worse than trying to go upstream in [river rapids][3]. Third, even if you somehow manage to make a probe that autonomously navigates upstream in thin underground lava corridors with surprise bends, you have to remember the underground magma chambers are not 100% liquid. They are what we call "crystal mushes", which is a pile of small crystals (i.e., bits of rock) with liquid in between. Think more like wet sand, than pure liquid. So you're not swimming in something with no resistance, you also actively have more solids out of your way. Fourth, molten rocks are **extremely** corrosive. You were talking about materials with high melting points. That's not your problem. Even the hottest lavas only get to about 1400 °C. We have relatively cheap materials that will magma at much higher temperatures. The issue is the reaction between the lava and the materials into making new materials, or dissolving completely in the magma. As an illustration, consider sodium chloride. Salt. The point at which it [melts][4], if you stick it into a furnace is around 800 °C. Surely, that's much above the temperature of let's say an ocean, and it might be a good idea to make submarines out of salt! Clearly, bad idea. Because the salt will just dissolve into the ocean. Whether it melts or not is irrelevant. So that's the big problem with your probes - the magma will simply dissolve it. ---------- So to sum up, you need your probe to be able to navigate in the dark and propel itself upstream in magma, be able to dig and clear space up front so it can move forward, and made of a material which is inert to the magma. Sorry - not happening. But a fun thought experiment nonetheless.
