Techno signals what we might have missed when looking for life beyond Earth

(ORDO NEWS) — Not too long ago, astronomer Jason Wright wrote an overview article in which he reflected on the search for traces of the activity of potential intelligent life within the solar system.

Saturn’s icy moon Enceladus is currently a prime candidate for the search for traces of organic life within the solar system.

It is believed that the warm subterranean ocean, which heats the core of the moon through geothermal mines, contains all the necessary ingredients for the preservation and even life of alien microorganisms.

If successful, their discovery will be one of the biggest scientific discoveries in the history of mankind.

Life Beyond Earth: What clues have we missed?

An article by astronomer Jason Wright titled Prior Indigenous Technological Species , published back in 2017, raises the question: have we exhausted all possibilities in the search for intelligent, and not just microscopic, life?

Contrary to expectations, Wright does not offer evidence for the existence of extraterrestrial civilizations, but speculates that humanity may have overlooked some critical “evidence”.

Wright proposes the idea of ​​searching for “techno signals” in the solar system. These signals are nothing more than traces of the activity of that life, which hypothetically could have existed millions, and even billions of years ago, on other planets.

It is known that Mars, and then Venus, according to astronomers, could once be suitable for life forms familiar to us. But how do techno signals differ from biosignals, which NASA intends to search for in the coming years?

Techno signals will tell more about civilizations than biosignals

The biosignal, according to Wright, is a sign of the simple existence of life, while the techno signal is evidence of its technological activity.

An example of a techno signal can be, for example, an artificial radio signal or an architectural building. The astronomer believes that if where one should look for traces of alien civilizations, then first of all in underground caverns of natural or artificial origin.

Such isolation could allow traces of man-made alien activity to survive even after huge (by earthly standards) periods of time.

Jason Wright:
“When we say “ancient” in relation to earthly culture, we mean that the phenomenon is a thousand or several thousand years old.

But on a cosmic scale, “ancient” civilizations are those that could be millions or even billions of years old, in which case they could have already ceased to exist long before life appeared on Earth.

So why haven’t we found traces of artificial activity on other planets yet? According to Wright, even earthlings are excellent at “masking” the traces of their activities: despite the flurry of activity for tens of thousands of years, ridiculously little is known about some cultures – all thanks to the accidental discovery of an archaeologist or paleontologist. Imagine how much the traces of even a highly developed civilization will be erased over millions of years!

In his work, Wright urges not to lose hope and suggests studying first of all the oldest rocks on Earth, in which unnatural isotope ratios can be found, which will give at least a hint of the potential activity of life that existed before humans.

Unlike the Earth, the age of the surface of Mars and Venus is huge, and therefore the study of their composition is much more promising: if no isotope traces are found on their surface and under it, then the solar system was most likely indeed uninhabited.
