Researchers believe that life on Earth was premature when compared with what happens on a Universal scale.
There is a clear conflict between the high likelihood of extraterrestrial life and the absence of any evidence for the presence of aliens. The paradox got the name of an Italian physicist who outlined the discrepancy between the scientific evidence and the calculations.
The years passed, and the “Fermi’s paradox” remained a question hard to crack. One of the theories was that the universe is colossal and that Earth and its occupants are insignificant dust spots amidst its billions of galaxies.
Another theory was recently distributed online in the Journal of Cosmology and Astroparticle Physics, and it points out the possibility that maybe life on Earth came too soon in the whole realm of the Universe.
The main creator of the theory, Avi Loeb from the Harvard-Smithsonian Center for Astrophysics, said in an announcement that it would be most likely to find life not now, but somewhere in a distant future.
How far into the future, the scientists did not say. However, Earth had a premature life occurrence. As the Universe is supposed to have the age of approximately 10 trillion years, an exact term ‘s hard to determine. The most important factor is the lifetime of the stars.
The life duration of a star is determined by its mass. Thus, stars that are three times heavier than our sun will explode way before life on the planets from their solar systems has an opportunity to develop.
“So then you may ask, why aren’t we living in the future next to a low-mass star? One possibility is we’re premature. Another possibility is that the environment around a low-mass star is hazardous to life,” said Avi Loeb, the leading author of the hypothesis.
When trying to discover extraterrestrial life, the scientists recommend looking out for stars that have a lower mass which would permit them to live longer. A longer period without any disturbances and explosions may allow life to appear.
The young stars emit strong streams of ultraviolet radiation which can destroy the atmosphere in rocky worlds and thus make the world inhabitable.
Despite the fact that cosmologists are still not sure whether life can exist in such conditions, they have predicted that the stars that have in their proximity planets with the size of Earth cover 6% of the total solar systems in our Universe.
The present study suggests that the chances to find alien life would improve in about 5 billion years, as the premature life apparition on Earth is thought to be somewhat of an accident.
