Enrico Fermi, an Italian Physicist, expressed an anomaly that seems unresolvable. He once asserted, "Where is everybody." If we exist, then Aliens can too. But a new theory says that we haven't met them as they haven't hatched yet. The study also divulges that we'll have to wait for long to encounter them. As the physicists from Harvard and Oxford deduced, beings of earth are the prime beings in the universe.
A team of astronomers conceived a research report for Journal of Cosmology and Astroparticle Physics. The researchers settled at an opinion that the chances of the evolution of Aliens can be at any moment and us at earth are premature.
Avi Loeb, a scientist at Harvard, said "If asked, when is life most likely to emerge? A simple mind might say, now. But we find that the chances of life will grow much higher in the distant future. "Loeb is the lead author of the study.
People must have caught the term ancient alien somewhere, but the study wants us to believe that we, the humans are the ancient aliens for real as per cosmic probability. The study can be dubious for the ones considering the earthlings to be extraordinary.
Since the evolution, organisms entailed only three aspects to survive. Those are a Carbon-based chemistry, water and a source of energy. The study states stars as the most vital need. Stars cause the fusion of photons and electrons to the carbon and other elements, heat the water in the habitats of living beings, and also provide warm radiations.
Stars have always assisted our researchers to comprehend the phenomenon of life. Researchers go back to the Big Bang to start with. The long-lasting red dwarf guides them further down the timeline. These stars exist for about 10 trillion years, much more than the yellow dwarfs. Red dwarfs are also gigantic in number in the Milky Way. The Red Dwarf is three-fourth of the total stars count.
Sun doesn't belong to the red dwarf family. It's rather a yellow dwarf much massive but lesser durable. So we are around a yellow dwarf according to the equations of the research intellectuals.
Loeb told the Smithsonian Magazine, "If it turns out that low-mass stars can support life, then we are special because we are one of the early forms of life."
Other aspects kept alike, a planet surviving longer has an astrobiological lead over others. The authors wrote, "We deduced the most conservative estimate of the probability of our existence. It's at most 0.1 percent before the current cosmic time." The researchers believe that life on dim red dwarfs has a greater probability in far future.
Alan Duffy, an Australian astronomer, wrote an email to Washington Post. He stated, "Many stars last much longer than our Sun. This ensures a bigger opportunity for life on a small dwarf star in future. The chances are better than in the last 13 billion years of cosmic time." Duffy was not the member of the team, he just expressed his viewpoints in the mail.
Loeb further adds in the press conference, "One possibility is we're premature. Otherwise, maybe a low-mass star has an environment hazardous to life." Many of the astronomy experts deny the same evolution of stars.
Charley Lineweaver, an Astrobiologist at the Australian National University, finds it a crazy thought. He says it seems crazy that life could be same on a yellow dwarf as it's here. The man expressed himself on a phone call to Washington post. He says life gets overpowered around a red dwarf.
James Kasting, a Penn State exoplanet researcher, talked to Popular Science. He says, "A lot of papers say that such stars may suppress lives around them."
Even if the state of a planet allows the existence of water around a red dwarf, the other aspects may be dismal for the growth of life. Then the world needs to stay nearby the dim dwarfs. But this location can roast the planet with intense radiations. Also, such a position can cause the tidal lock. Hence it would disturb the fair distribution of day and night on the faces of that world.
Leanweaver thinks the theory of the research has rigid grounds. He is quite impressed with the modus operandi but disagrees with the conclusions drawn. He felt that the research team neglected the possibilities of life on tiny stars. Duffy also showed the same concern.
Duffy penned, "Authors calculated assuming life to stars just 90 percent of the mass of our Sun. Numbers say that the most likely star to find ourselves in and around is a Sun resembling star."
He adds further, "We don't know what does matter, we have just one Solar System to examine. We can't know yet what makes it unique in harbouring life."
Thus at the end of everything, the conclusion becomes too dubious for us. If we trust Leanweavers's analysis of metal formation in stars, the earth life began pretty much later than other existing lives. Another paper of his raises the possibility that we are alone because Aliens are extinct.
As of now, the above research is just another angle to see the issue of undiscovered Aliens. Nothing proves anything about it in the current scenario.
