Scientists Dug The Deepest Hole On Earth But This Broke Their Drill

The Temperature Changed

They had overestimated the rate at which the temperature would increase. The temperature in the hole had reached 180 °C (356 °F) by the time they got close to the target. This is 80 degrees Celsius (176 degrees Fahrenheit) warmer than they had anticipated!

That wasn’t the only difference. Furthermore, the researchers found that the granite at such depths was far thinner than previously believed. As a consequence, it responded to higher temperatures in unanticipated ways.
