Why is the inner core of the earth a solid metal when it is hotter than the outer core???

Hi Rdm1122

Because of the enormous pressure. As the depth get greater - the pressure become higher and higher and the  liquid outer core become solid.

Have the scientists ever considered the possibility that Earth’s inner core could be the coldest zone of the planet? Maybe the scientists are in the worst paradigmatic paralysis of all times
 

The nucleus of the earth is the coldest zone of the planet. Inner core is a huge bubble floating in the center of the earth. It has an empty space of diameter ?1.326 kilometers in its center. Outer and inner core have paramagnetic liquid and solid oxygen respectively. Magnetic fields of the Sun and Earth interact in time of global heating. Polarity reversal of the earth magnetic field may occur soon.

I could send a copy of a summary of this theory if it would be of your interest.
