Anomalous ejection from two distant galaxies could mean the existence of hyper-advanced aliens

The team of researchers analyzed 21 galaxies with high levels of radiation in the mid-infrared range.
To their surprise, they found that four of these galaxies had their radiation amplified by a factor of 10. Two of them were explained by natural processes, while the other two remained unexplained.

A team of researchers has discovered two distant galaxies that could harbor advanced alien civilizations.

Traces of unusual activity have been found in both galaxies, which may indicate the presence of a type III extraterrestrial civilization on the Kardashev scale.

One of humanity’s deepest and most important questions is “Are we alone in the universe?”

The deeper we look into the universe, the more galaxies we discover. Going by the numbers, as of 2022, researchers estimate that there are more than two trillion galaxies in the observable universe.

In our understanding of the cosmos and the number of galaxies that have come into being since our universe began 13.7 billion years ago, the Bubble Space Telescope is of immense importance.

One of the deepest images of space is the so-called Hubble eXtreme Deep Field.

This image revealed the faintest and most distant galaxies ever seen and allowed experts to look further into the past than ever before.

But even with this picture of some 5,500 galaxies, we are a long way from understanding the number of galaxies in our universe.

are we alone in the universe?

Although this question cannot be answered with certainty today, we may be close to finding out.

Researcher Honging Chen and his colleagues from the National Astronomical Observatory of China scanned part of the northern sky.

Their goal was to see where exactly in this area there are signs of hyper-advanced extraterrestrial civilizations.

Of the 21 galaxies they examined, two galaxies stood out with anomalous features.

Their results were presented in a study published in the Monthly Notices of the Royal Astronomical Society.

Traces of advanced alien civilizations?

The universe is really gigantic. Given several factors, such as the age of the universe, the number of stars and galaxies, it would be presumptuous to consider Earth the only planet where life arose.

Perhaps somewhere in a distant galaxy, not so similar to the Milky Way, a civilization arose that developed over millions of years and surpassed even our greatest technological achievements.

Kardashev scale

To understand how advanced a possible alien civilization could be, we use the Kardashev scale, developed by astrophysicist Nikolai Kardashev in 1964.

It measures how technologically advanced a hypothetical extraterrestrial civilization is based on the amount of energy it consumes. The scale includes three types of civilizations:

civilizations of the first type

This is a potential civilization that is technologically advanced enough to use all the energy of its home planet.

Civilization of the second type.

This potential civilization could harness the energy of the entire solar system, its sun and its planets.

Type III Civilization

This potential civilization has reached such a level of technological development that it can harness the energy of the entire galaxy.

A civilization of the third type can easily use the many stars in its galaxy as sources of energy by building hypothetical mega-structures called Dyson spheres.

By doing so, a civilization could harvest all the energy produced by a star.

Thus, by using thousands, rather than millions, of stars in its galaxy, a Type III civilization could meet its increasing energy needs, allowing it to further evolve and explore the universe.

If a Type III civilization were to place Dyson spheres around many of their stars in their home galaxy, we could probably find traces of them.

This prompted Chen and co-author Michael Garrett to use the 2-meter LOFAR Two-meter Sky Survey (LoTSS) to search for any infrared signals indicating the presence of these megastructures.

They combed 21 galaxies with high emission in the mid-infrared. To their surprise, they found that four of these galaxies had a 10-fold increase in emission.

“Two of them have been identified as natural sources: one was an active galactic nucleus and the other a star-forming galaxy, which means that their excessive mid-infrared emission is the result of different mechanisms,” Chen says.

“We don’t know the reason for the high mid-infrared to radio ratio of the other two.”

According to InVerse, the radio and infrared emissions from each galaxy correlate with each other. The radiation from galaxies transmits information about their heat through the infrared spectrum.

As part of their search for what looks like extraterrestrial escape, the duo have been investigating the mid- and far-infrared spectrum, Chen explains.

A Type III civilization will produce excess mid-infrared radiation due to residual mid-infrared heat, which will affect the correlation.

Of the 21 galaxies, two stand out and are possible host galaxies for Type II alien civilizations.

In both galaxies, the researchers were unable to understand what caused the burst of radiation in the mid-infrared region.

While extraterrestrial civilizations may be to blame, other natural explanations, such as an unusually high rate of star formation or an extremely bright galactic nucleus, cannot be ruled out.

It is likely that the galaxies ILT J134649.72+542621.7 and ILT J145757.90+565323.8 will be analyzed in the near future. In his paper, Chen and his colleagues conclude that both galaxies “deserve further study.”

Whether these galaxies are home to powerful and advanced alien civilizations remains to be seen.

Future studies of galaxies and observations in various spectra may help us answer one of the most important questions that our species has so far been unable to answer.
