Declassified NSA Document Reveals How Aliens Will Contact Us
We may not even need to fly to distant worlds to meet aliens. They may try to contact us.
Statistically speaking, we are probably not alone in the universe. Given the abundance of stars that likely host Earth-like planets with liquid water, life, and a temperate atmosphere, alien civilizations may have already arisen, flourished, and traveled through interstellar space.
In that case, we might not need to populate distant worlds to find them. They may try to contact us.
A declassified National Security Agency document shows how some of the world’s top scientists believe that an alien intelligence might try to make contact with the human race.
With the development of man-made technologies, new ways are increasing in which an intelligent alien species can make contact with humanity through the abyssal depths.
More and more scientists agree that contact with alien civilizations can be a part of our social evolution, as natural as our accidental discovery of radioactivity or our first steps on the moon.
It is no longer something beyond our wildest dreams, but a natural event in human history that will likely occur during the lifetime of many of us, according to a declassified article on the NSA website.
The Milky Way contains at least 100 billion stars. According to NASA research, there could be as many as 400 billion stars.
Periodically repeated laser pulses can be the best means of interstellar communication, as they can cover indescribably long distances.
Another method involves moving the stars in an easily recognizable geometric pattern that would instantly signal to any observer: Note that this is not created by nature!
“They could build something that could be seen from a huge distance across the entire galaxy, or even from another galaxy, which would clearly be artificial,” said astrobiologist David Grinspoon of the Planetary Science Institute.
Some astronomers believe that alien megastructures in the universe could be a message that life exists there.
However, the best-known theory of the megastructure will likely be the dimming of stars rather than interstellar SOS.
Research in 2019 suggested that the “flashing” star could be caused by the destruction of a foreground exoplanet.
Conventional radio is quite reliable when making interstellar contact. Radio waves have served as scientists’ primary means of listening for alien signals for nearly a century.
Radio waves are incredibly resilient, passing unhindered through the darkest depths of the galaxy. They are reliable, although they spread slowly. Radio waves travel at the speed of light. For example, if the nearest star is more than four light-years away, the answer will take eight years.
