Scientists returned to the theory that intelligent life could exist somewhere in the Milky Way, and talked about what it might look like.
This time, the researchers used the Murchison Wide-Field Radio Telescope to find an artificial signal at the center of the Milky Way, suggesting an intelligent civilization.
According to preliminary simulations, the best conditions for the emergence of life may exist near the center of the Milky Way at a distance of 3,200 light years.
So far, as before, observations have not brought positive results. But that doesn’t mean life doesn’t exist, scientists say.
In their opinion, intelligent beings may exist, but their civilization is not sufficiently developed to use radio waves, or the alien signals have not yet reached the Earth. As a result, humans could be the most technologically advanced species in our galaxy.
But how many galaxies are there? Counting them seems like an impossible task. While estimates among different experts vary, an acceptable range is between 100 billion and 200 billion galaxies, said Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland.
So if we are the most advanced civilization in our galaxy, we can only imagine how far extraterrestrials have evolved in other galaxies.
