Recently, on a working vacation with the family, we watched a movie wherein the hero traveled to the center of the earth in order to save it. Now being the curious sort, I figured out the degree of plausibility of such an endeavor. Here it is:
The earth’s core is estimated to run at a balmy 10,800 degrees Fahrenheit. Titanium melts at 3,034 degrees Fahrenheit. The pressure at the core is estimated to run in the neighborhood of around 3.6 million atmospheres. Since the core is solid nickel/iron, this equates to about 13,000 kilograms of pressure per cubic meter. In short, any crew in any vessel in this situation would be squashed and toasted beyond all recognition. Hollywood screenwriting magic, folks!
