Chthonian Theory states that the Earth started its existence 4.6 billion years ago as a gas giant. The fusion ignition of the Sun stripped away the Earth’s outer shells and thus it became a chthonian planet. Approximately 180 million years ago started its rapid expansion as a result of force balance between the cracked rigid mantle and previously highly compressed interior. The expansion led to a creation of the oceanic lithosphere and Earth’s primordial heat loss. It is a competing theory to the theory of plate tectonics and thus e.g. rejects a process of subduction.
Feel free to enjoy my last lecture on ‘Chthonian Earth Theory’ with English subtitles. The lecture was held on 20 December 2017 at the Faculty of Science of the Charles University in Prague.
Of course, I will appreciate a feedback from you 🙂
