Timetrek: the natural history of the world
This course provides a basic education in the new field of astrobiology.
Astrobiology provides a multi-disciplinal approach, using the tools of all natural sciences, to address the basic questions related to the prerequisites, existence, origins, occurrence, evolution, as well as the foreseeable future of life in the universe.
This field is strongly promoted by the different space agencies in the world (such a NASA, ESA, JAXA) and it is also taught at least on basic level in most of the large Universities in USA and Europe.
So far, no examples are known of any other planets that would host life, except for our Earth. Therefore the history of planet Earth and its biosphere are presented here as the study case, and an example, to describe a habitable planet, origin and the evolution of a biosphere, throughout the times.
The course also presents the current search for the existence of extra-terrestrial life forms.
Date: 9th of August to 20th of August 2021.
Place: If the covid-19 pandemia will prevent student travel or assembly on site, the course will be arranged on-line.
Credits: 5 ECTS
Application: by 12.4.2021 via online form
The students will learn the basics of astrobiology and the structure of the Universe. They will learn the most important developmental stages of the world, their physical and chemical characteristics, regulatory interactions, causes and consequences, the prerequisites of the existence on life in the Universe or on a given planet, and the habitability parameters of planets.
The student will have a good understanding of the
- History of the Universe
- Formation of the planetary systems and particularly of the Earth
- Proposed scenarios for the origin of life
- Principles of evolution, the terrestrial conditions that have driven Evolution on Earth
- Major stages of the evolution of terrestrial evolution
- Rise and consequence of the technical civilization
1) Evolutionary stages of the Universe and its guiding parameters and natural laws,
2) The universal preconditions of the existence of life,
3) Prerequisites of life in the world. Planetary habitability,

5) Origin of life, and early biosphere,
6) Life evolves, and alters the global conditions,
