Jan Mestan

Globe maker, adventurer, geoscientist and yes, I connected Zealandia with South America ūüôā




The first science I discovered was astronomy. I spent hours and hours under the dark sky observing the stars, planets and celestial phenomena. The year 2007 was specific for me since I won two student competitions – National Finals of the Astronomy Olympiad and a Catch a Star! contest organized by the European Southern Observatory. As a winner of Catch a Star!, I had the chance, together with my schoolmate Jan and our physics teacher Marek, to visit the ESO facilities in northern Chile. This was the first time I observed the southern sky or the Andes – and here, I had to ask. How did such mountains as the Andes form?



A few years later, I decided for geology and geophysics. I spent few semesters between two excellent European universities – the Charles University in Prague and the Ludwig-Maximilians-University in Munich (here as a GFPS e.V. and Bayhost scholar).

My projects in geosciences include:

Industrial Use of Radiometric Dating Techniques

Radiometric dating is a unique field of geology that allows us to study the relations of rocks in the age reference frame. It is often used in scientific papers with lesser accent on the industrial applications. The project has the aim to emphasize the industrial use through development of new techniques and practical solutions.

Aircraft Landing Seismicity

The aim is to decide whether it is useful to evaluate the aircraft landing via seismic. Landing seismograms could provide valuable information about aircraft damage in the future.

And many other projects like small-scale seismic vibrator testing (part of my B.Sc. thesis), Rajlich’s Hypothesis or currently the Chthonian Theory.



I heard about the possibility that Earth might be expanding during my studies, but it was usually mentioned like a marginal or obsolete hypothesis. In 2017, based on the best VGG maps of the Earth we have ever had, I realized that Zealandia can be put together with the continental edge of western South America. And I proclaimed: Eureka! No reconstruction from e.g. Hilgenberg, Vogel, Herndon, Maxlow or comic maker¬†Adams mentions the exact way the Pacific was connected 180 million years ago during the Pangea breakup on smaller Earth than it is today. But now, I see everything. This was the breaking point when I definitely decided to throw the plate tectonics theory away. And also decided to come with a brand new theory –¬†the Chthonian Theory.



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.


At CSD 2015, I presented GPS data use in geological prospecting.


The brand new concepts in the theory are for example the Earth’s icy sarcophagus (the clue for Earth’s water origin) or¬†Herbig-Haro objects and their effects on Earth’s primordial gaseous shells uncovering. Another new concepts and findings will time bring.







Really new trails are rarely blazed in the great academies.
