Aliens gave Earth life through an asteroid? This NASA scientist has something to say

The theory of the disease ‘panspermia’ has always intrigued scientists. But now, a NASA scientist offers his opinion on whether life on Earth could have started because of alien microorganisms transported by asteroids.

When it comes to the puzzle of the origin of life on Earth, scientists have different theories about it. While it is thought that life began on Earth itself when the oceans began to fill up with organic chemicals that later turned into complex proteins, there is another, much more intriguing hypothesis that the interested scientists. Called panspermia, it states that life on Earth may have come from another planet or celestial body in alien form. And how did it happen? Microbial single-celled organisms arrived on Earth through asteroid strikes and then self-dispersed to begin the journey of life on Earth. Obviously, the latter seems a bit far-fetched, but many researchers think it’s likely to happen in our solar system.

But a senior research scientist at NASA disagrees. In one statement gave The Tech Outlook, he said, “If the journey takes millions of years, then the life will die and it doesn’t matter if it’s life on Earth or life beyond Earth… Why? Because it will be destroyed by cosmic radiation. And even if it could survive like that, the radiation emitted by the minerals in the rock would destroy it.”

Panspermia suggests Life on Earth came from Mars riding an asteroid

But as a counter argument, an interesting theory about panspermia has emerged and it is related to Mars, our neighboring planet. As reported by The Tech Outlook, a team of scientists at Tokyo University of Pharmacy believe that 4 billion years ago, when Mars could support life, some Mars bacteria may have reached Earth due to a planetary fragment collides with our planet and in turn, releases spores of life. This theory even takes care of the theory’s criticism that no life can exist in space with all radiation for a long time, essentially eliminating the possibility of life. from another galaxy. And it’s more interesting when you consider a bacterium called Deinococcus radiodurans.

A team of scientists at Tokyo University of Pharmacy has demonstrated that Deinococcus radiodurans is a very interesting single-celled organism that can survive for at least three years in space. The research took place in a simulated environment similar to the International Space Station. The findings were published in Frontiers in Microbiology, a peer-reviewed journal. “We showed [the bacteria] would survive by doing these experiments on the ground, and they accepted us and believed us,” the researchers told Tech Outlook. Then the experiment was repeated in real space and it was found that a large number of bacteria managed to survive.

So while there is a long way to go for panspermia to truly become the leading theory on the origin of life, the Tokyo researchers believe this is a major breakthrough.
