According to the director of Roscosmos, advanced alien civilization may be sending out signals across the galaxy, but these are simply imperceptible for us right now. In other words, we can’t possibly say there’s no one out there. There might be, but we just can’t hear them.
Many people have asked throughout the years; “If aliens really exist, why haven’t they sent out a message to make their presence known?” Well, it turns out that they may have, but we just might have missed their signals because to us, their message may seem imperceptible. This is according to astronomers who believe that we can’t possibly say there’s no one out there just because we haven’t spotted any alien signals so far.
For all we know, aliens may have been trying to phone Earth for decades, but humans simply can’t understand or even notice them.
Accordion to Roscosmos Executive Director for Long-Term Programs and Science Alexander Bloshenko, extraterrestrial signals from advance civilization in the cosmos may have been coming to earth for a long time, but there’s a chance that humans “simply fail to understand their principle.”
As noted by Bloshenko in an interview with the Russian News Agency TASS, we can’t possibly be sure that the Universe is definitely silent, even though to date we’ve not registered any signals that originate from an artificial source.
“It is quite possible that some signals based on non-classical principles incomprehensible for us today are going through Earth,” Bloshenko explained. Bloshenko made an interesting point during his interview. He revealed that the existence of exoplanets orbiting their host stars in the so-called habitable zone indirectly suggests that there are places in the cosmos that are favorable for life as we know it to emerge.
As it turns out, to date, NASA has found more than 4,150 (confirmed) exoplanets, many of which orbit their host stars in the so-called habitable, or Goldilocks zone. There are other 5,142 candidates, many of which will turn out to be real exoplanets. According to our best estimates, there are between 100 and 400 billion stars and at least that many planets.
“Currently, it is conclusively known that about 4,000 exoplanets [the planets of other stars] exist. At the same time, over two trillion galaxies are located in the visible part of the Universe and in each of them trillions of planets may exist. And the probability that life similar to ours exists on any of them is quite big,” the Roscosmos official added.
To understand whether we are alone in the universe depends on many factors. The most important one is our ability to scan the skies for potential signals and look for planets that are similar to Earth. However, it is imperative to study our solar system and find out where places like Mars or the moons of distant planets like Enceladus or Europa meet the necessary conditions for life as we know it to exist on, or beneath their surface.
Recently, astronomers reported discovering a one-in-a-million exoplanet towards the galactic center. The researchers say that the super-Earth is comparable both in size and orbit to Earth, although it is believed to have a mass four times that of our planet.
