How can dead alien civilizations save humanity?

Those who are not able to learn from the mistakes of extinctalien civilizations run the risk of repeating their fate. Humanity has set foot on a very dangerous path. We have learned to develop weapons that can destroy all of us many times. We don't care about the environment, turning a blind eye to climate change, which they themselves have created for decades, not really thinking about the future consequences. Similar recklessness on such important issues could put an end to advanced alien races that may have once inhabited our galaxy, says Avi Loeb, dean of astronomy at Harvard University and director of the Institute for Theory and Computation of Astrophysics.

This, Loeb says, might in turnexplain why we still have not made contact with any of the possible alien civilizations, despite the proper diversity of life in the Milky Way (at least, this is the statement of the famous Fermi Paradox).

“One explanation for this is thatthese civilizations as well as we did not think about future consequences. Using a short-sighted approach to development, they could open those wounds that ultimately killed them, ”said Loeb as part of his speech at The Humans to Mars summit, an annual event to discuss deep-space exploration, recently held in the US capital.

Therefore, Loeb believes, we must expand ourthe circle of the search for aliens, not limited to only the planets, which from an environmental point of view can look habitable. We must also look for planets with artifacts of man-made disasters. Artificially scorched surfaces of the planets or signs of nuclear wars that could persist in the atmosphere of the dead worlds, as an option, would be excellent evidence in this regard. Most likely, such discoveries will not only become the greatest in scientific history, but also, perhaps, will open to us, as a species, eyes on how not to dispose of your future.

“The bottom line is that during this process we, II hope we can learn something very important. We can finally figure out for ourselves that it is better not to arrange internecine conflicts, not to initiate a nuclear war, but instead take better care of our planet, making sure that we can leave it habitable as long as possible, ”Loeb says.

According to a Harvard University scholar, there areand other reasons to try to find intelligent and technologically advanced extraterrestrial life. For example, explains Loeb, establishing contact with an alien civilization can lead us to significant technological breakthroughs, if, of course, aliens want to share their technologies with us.

“Our technology is only a century old, but if a different civilization had billions of years to develop the same space travel technologies, they could well teach them and us,” said Loeb.

According to the scientist, such perspectives are worth continue working on the development of interstellar travel technology. Loeb, we recall, heads the advisory board of a very ambitious project Breakthrough Starshot with a budget of $ 100 million, whose goal is to develop tiny space probes based on laser technologies that are supposed to be sent to another star system at a speed of 20% of the speed of light.

Breakthrough Starshot Project Scientists Countdevelop technology fully ready for interstellar travel over the next 30 years. If the project proves successful, sensible aliens, Loeb thinks, “can see humanity in a new light”. We will be able to gain among them a certain level of respect, putting us, if not on a par with them, then at least a bar above our current position.

"I hope that the discovery of the lost civilizationsinspire us to more thoughtful actions, and also unite us as a species. I also hope that as soon as we have the opportunity to get out of the solar system, we will receive a message: "Welcome to the club of interstellar travelers." And then we learn that in fact our galaxy is much more populated than we used to think, ”says Loeb.

According to him, we could already become onewitnesses. Loeb is a co-author of a recently published article suggesting that Oumuamua, the first interstellar object found in the solar system, may in fact be the probe of some alien civilization. The controversy over the nature of this object continues unabated, but at the moment most scientists are inclined to believe that Oumuamua is an unusual comet with no tail. But, again, according to Loeb, it is very important not to dismiss the theory of the artificial origin of this mysterious small celestial body simply because you do not like it.

“We must maintain an open mind in suchresearch and do not try to stand out due to the simple desire to show that we know all the answers in advance. There is no point in pretending here, ”concluded Loeb.
