Why the interior of the Earth is still hot and inner core of Earth should be cooled after billions of years and why is it still so hot even hotter than surface of Sun?
According to the results of my core model: the core of the earth is like a black hole under the pressure of compressed gases that constantly surround the black hole and thus cause the internal rotation of the earth and. .. these pressures cause the core to heat up. For the Earth's core to cool, first the Sun and eventually the entire universe would have to stop rotating, which is impossible because then the entire universe would collapse. Eventually, there will be moments when the rotation of the Earth's core and crust reverses. As a result, the friction between the core and the crust causes heat and the heat of the crust and soil of the Earth like the planet Venus.
