Life on Earth can come from the universe

Some scientists believe comets carried the materials needed to form life on Earth about 4 billion years ago.

Hypotheses about the origin of life on earth

Panspermia theory , first introduced in 1871, has been deemed impractical, but now the situation has changed, according to New Scientist. This theory suggests that life is brought to Earth by comets and meteors.

The Panspermia theory has increased recently, water and organic molecules are found in comets that fly through the solar system. Some even argue that life is built up and brought to Earth, where conditions are perfectly developed.

"I think it's possible to consider Mars as the source of life on Earth , " said biologist Pete Ward, a University of Washington biologist in Seattle. He also said that if there is evidence to prove the origin of life is from extraterrestrial, there will be great impacts on scientific and religious views.

"It will be a great shock. For some orthodox religious notions, only one place exists, that is Earth."

Many scientists believe that sudden life appeared on Earth about 3.8 billion years ago, just at the time of the perfect conditions to promote life development.

Professor Chandra Wickramasinghe, an astrophysicist from Buckingham University and a supporter of Panspermia theory, believes that the Earth continually exchanges organic matter and living matter with planets of the solar system. vicinity.

In an article in the Astrobiology Journal released earlier this year, Professor Wickramasinghe and his colleagues explained how life is brought to Earth.

"It is estimated that there are about 140 billion planetary systems in our own galaxy, most of which are linked to" red dwarfs. "The average distance between planetary systems matching life is only a few. light years Because these distances are relatively short, planets can be connected by dust, debris, meteorites and comets. "

Simply put, when comets go "travel" through the planets, it can send back "passengers" as molecules and creatures.

According to the chart shows small and low-temperature HR , "red dwarfs" . They occupy the vast majority of stars and have less than half the mass of the Sun and have a surface temperature of less than 3,500 K.

Wickramasignhe and his colleague, Dr. Milton Wainwright - cite the remains of "microorganisms" collected by a balloon at a height of 26 km in the stratosphere during the Perseid meteor shower in 2013. They also studied matter on meteorites, found to have structures similar to fossil microorganisms.

Even scientists from the US Aeronautics and Space Administration (NASA) also believe that finding evidence of the existence of life outside the solar system is only a matter of time.

NASA used simulated meteors to shoot into space and let them fly back into the atmosphere. The results show that DNA and some bacterial spores can survive in extremely high temperatures and extreme pressure when flying into the Earth's atmosphere.

This has contributed to consolidating and serving as a basis for Panspermia theory. Some of the leading scientists, including Professor Stephen Hawking - the father of the theory of all things and a black hole discoverer, supported a $ 100 million plan in July to look for life outside. Earth.
