In their quest to understand the origin of life, scientists wonder especially about the favorable conditions for its emergence. Several hypotheses have already been formulated. And today, researchers are suggesting that life on Earth may have received a slight boost from supernovae that appeared in the past billion years.
According to the time-honored expression, we must have come from ” From,, But the exact scenario of the presence of life on Earth is yet to be written. Today, Come to write a new page. She explains the close link that would exist between life on Earth and the number of Which explodes in a supernova near our planet.
Researchers have actually observed a correlation between the proportion of buried organic matterand changes in the occurrence of supernovae. They report that this correlation can be found in data from the past 3.5 billion years. A little more than in the last 500 million years. This could prove that the explosions of stars in supernovae participated in the establishment of favorable conditions. ,
how? ‘ or ‘ what? effect of cosmic raysand on of our planet. Because we must remember that when massive stars explode in supernovas, they produce cosmic rays that carry higher particles , When cosmic rays come into the vicinity and they hit the earth, they hit a certain Our ,
Effects on Climate and Oxygen
However, previous studies by the same team of researchers were able to show thatparticipate in the formation and growth of , Clouds are also formed due to the effect of impact. And clouds, it is clear, play on the amount of solar energy that can reach Earth’s surface. Empirical evidence confirms that there is a significant relationship between cosmic radiation and climate. on a geological scale, The origin of these cosmic rays can vary by several hundred percent. Hence, significant impact on our climate.
Therefore, during the period when most supernovae came to light, the climate on Earth became cooler. significant temperature differences have arisen betweenand poles. From Blown strong. And the oceans mixed. to provide and spread a lot , The result: greater bio-productivity and more organic matter in the sediment.
The researchers explain that the suppression of organic matter in the sediment also makes it possible to produce the oxygen necessary for life. It’s actually classically constructedfrom water and of (CO)2) but if we imagine that the organic matter is not directed towards the sediment, it turns back – along with the organic matter in question – into CO2 and water. Another way for supernovae to affect the development of life on our Earth.
