Aliens Might Not Be Far Away

Evidence That We… Are Aliens

Humanity may have moved one step closer to an answer to the eternal question: Where did we come  from? By 2022, a series of studies provide evidence to support the theory that life on Earth came from space.



A long-running theory in astronomy, once considered crazy and only seen in sci-fi movies, is now increasingly proving to be true: Life on Earth came from space and arrived on Earth via a “train” of comets and asteroids when Earth When I was still young.

In recent years, a growing body of research supports this curious hypothesis. Most recently, in February 2022, work led by Dr. S.A. Krasnokutski of the Max Planck Institute for Astronomy and the Astrophysics Laboratory Group of Friedrich Schiller University Jena (Jena, Germany) focused on peptides, which are A smaller version of a protein, one of the building blocks needed for life to exist, to recreate its history 4 billion years ago.

According to Science Alert, they used an ultra-vacuum chamber with some substrates to simulate the conditions in a cloud of cosmic dust to show that aminoketene—a chemical precursor that makes peptides—can be directly absorbed in this strange environment. form.

The study, published in Nature Astronomy, claims that 4 billion years ago, things that were proven to be born from this cosmic “smelter” landed on Earth and sowed the seeds of life.

The material for this cosmic melting pot must be an environment with a variety of chemical compositions—something that didn’t exist in the chaos of the early universe. Research by Japan, the United States and Australia, published in The Astrophysical Journal in October 2022, addresses this question: These are supernovae from Population III.

Cluster III stars are the oldest group of stars in the universe, observed by super telescopes billions of years ago when they “traveled through space” to Earth, with the oldest stars over 13 billion years old.

These stars, like modern stars, explode as supernovae at the end of their lives. It was they who “pumped” a bunch of elements into the poor early universe of hydrogen, helium and a little lithium.

The last piece—what brought life to Earth—continues to be demonstrated by meteorites that have fallen into our world, bearing various layers of so-called “building blocks of life.”

In a study published in Nature Communications in April 2022, this line of research also breaks new ground in 2022. In three famous meteorites that fell in Murchison, Murray (Australia) and Lake Tagnish (Canada), scientists have found something most shocking: traces of DNA!

The Sci-News newspaper quoted Dr. Yasuhiro Oba of Hokkaido University (Japan) as saying that they tried to find two nucleobases, purines and pyrimidines. These two classes of organic molecules can be synthesized in extraterrestrial environments, so they hope to be able to identify them in these space rocks.

The results not only confirmed the presence of these two nucleobases, but also a series of other nucleobases. Nucleobases are the “chemical building blocks” that make up the basic structures of life: DNA and RNA.

The team of scientists said the discovery was not enough to directly show that life on Earth – including us – came from some distant alien world, but it could help demonstrate how the basic structure of life in the universe was formed and how it came to be. to Earth.
