The Connection Between Supernovas and Life on Earth

According to new research on the accumulation of organic matter and the frequency of supernovae on our planet life on earth It exists only because of the powerful explosion of a large number of nearby massive stars, also known as a ‘supernova’ it could be.

Senior researcher from DTU Space at the Technical University of Denmark, Dr. If we look at the article published by Henrik Svensmark in the scientific journal Geophysical Research Letters, the relationship between the organic matter fraction embedded in sediments and the frequency of supernovae. a close connection exists. It is recorded that this rather surprising connection is valid for the last 3.5 billion years.

Supernovas directly affect Earth’s climate and indirectly affect oxygen production

The evidence obtained in the research, climate change It seems to be related as well. Accordingly, many supernovae; It leads to a cold Earth climate with large temperature differences between the equator and the poles. This results in stronger winds and choppy seas that help transport nutrients into ecosystems, resulting in greater bioproductivity and more organic matter embedded in sediments.

Most importantly, in this process, it is the basis of all complex life on Earth. oxygen is revealed. Svensmark noted that the photosynthesis process produces oxygen and sugar from light, water and carbon dioxide (CO2). “However, if the organic material is not transported to the sediments, the oxygen and organic matter become CO2 and water… burial of organic material prevents this reverse reaction. “ expresses as. This means that even if supernovae are indirectly It controls oxygen production.

Svensmark, which measures the elements found on the seafloor; compared the valence levels of the lighter and more life-friendly carbon-12 atom with the heavier carbon-13 atom. As a result, Svensmark determined the ratio between these two atoms according to the amount of biomass in the world’s oceans. that it changes he noticed.

Supernovas also control how much of the energy from the Sun reaches the Earth’s surface

So what does this have to do with supernova? Svensmark this, “When heavy stars explode, they produce cosmic rays made of elementary particles with enormous energies” he explains. These, in turn, ionize the atmosphere when they hit Earth’s atmosphere, causing aerosols to form, grow and eventually increase the amount of clouds. In this case, the sun’s energy how much of it can reach the Earth’s surface directly affects.

On the other hand, while Earth’s climate is known to change with fluctuations in the intensity of cosmic rays, the frequency of supernovas can vary greatly. Regarding this Svensmark, “New evidence suggests that cosmic rays are mediated by the effect on clouds and climate, An extraordinary link between life on Earth and supernovasor pointing uses expressions.
