Cold gas planets like Neptune are much hotter
LoopdoctorOctober 26March 60Level I Student
The temperature of Neptune’s upper atmosphere is very low, but high activity levels like geysers were seen by Voyager 2 in 1989. Surprising because current publications estimate the core temperature at only about 5,400 [Kelvin].However, based on Noether’s theorem of energy conservation the core must be...
Earth’s core temperature calculated, not guessed
LoopdoctorFebruary 11February 170Level I Student
The cause of the high temperature of the inner core of the earth is currently thought to be radioactive decay and residual heat. This article provides a different explanation: Energy conservation. Imagine a tunnel through the earth and calculate the potential energy of a molecule at the surface and in the core. You...
