A new study shows how life could spread through space in the most basic way
Until now, theories about the origin of life on our planet have been very varied. And there are as many possibilities as there are points of view when approaching a problem. However, the new study would suggests something very interesting: that life came to our world from others, through cosmic dust that slowly spreads through the galaxies. We’ll see What is this theory supposed to give us? and why it is so valuable for future space exploration.
A new theory of the origin of life on our planet
Cosmic dust, according to a study published by ZM Osmanov of the School of Physics of the Free University of Tbilisi, Georgia may be the means by which life spreads through the universe, a process known as panspermia in our world. This new way of understanding life in space suggests that life on Earth may have started its journey from other corners of the universe, arriving at our planet aboard interplanetary dust particles.
We have to go back to 3.5 billion years ago when life on Earth simply began. This brings us to a chronology of just 500 million years after the planet’s formation. Something that succeeded many experts question whether it is possible for life to arise naturally on our planet at such an early period.
The study, for its part, suggests that life-carrying dust particles They could have escaped the gravitational pull of other planets. These particles, driven by solar radiation pressure and their initial velocity, would have the potential to leave their star system of origin and spread throughout the universe. Something that plays a big role in favoring new discoveries like water in asteroids.
Calculations indicate that these dust particles could have hit up to 105 star systems over a period of 5 billion yearsand that the journey to the nearest star system It could only take 9,000 yearsunderstand it just as something from a spatial point of view, because these are processes that usually take millions of years.
The interesting thing about all of this is that it leads us to think so There could be a huge number of planets with primitive life formsscattered by space dust, especially when considering issues like the possibility that there are planets colliding with each other that could emit even more space dust into space.
This gives us a lot to think about and at the same time presents us with millions of possibilities that look like the result of a science fiction movie. In any case, it opens up a horizon for astronomers to refine their detection of possible simple life forms virtually any planet found by our sensors.
In short, the key to study is as follows:
- Research suggests that cosmic dust could somehow spread life throughout the galaxy panspermiathereby creating life on Earth by way of other places.
- Earth had traces of simple life 3.5 billion years ago, just 500 million years after its formation.
- The research questions whether it was possible for life to exist at such early times.
- The study seeks to investigate whether life-bearing planetary dust particles, escaping the planet’s gravitational pull, could leave the star system driven by radiation pressure and initial velocity and spread life around the world.
- Dust could reach 105 star systems in 5 billion years, the nearest system would take only 9,000 years.
- There must be a huge number of planets with primitive life.
