There is no alien or extraterrestrial creature, study says


IllustrationIllustration - A number of predictions about life outside the Earth is again bursting. One of the prediction seems that humans will not be the victims of alien invasion.

The group of researchers who are the members of the Future of Humanity Institute, one of the research centers at the University of Oxford, do a calculation to find out if there really is life in outer space. The answer? It may be a bit of a disappointment for people who want to meet aliens.

An analysis named Drake is able to calculate the possibility of life in space by combining all the aspects needed to enable the birth of civilization somewhere. From there, it appears the percentage of how likely there is life other than in this human-inhabited Blue Planet.

Through these calculations, they claimed most likely no other life in the universe, with a percentage of 39% to 85%. Meanwhile, if the scope is reduced, only in the Milky Way Galaxy, the possibility of no life other than on Earth becomes larger, or between 53% to 99.6% as quoted from The Guardian, on Tuesday, July 3rd 2018.

Ellen Stofan, former chief researcher at NASA, also gave an opinion with the same pessimistic about the existence of aliens. According to him, life in space could indeed exist, but not as smart as many people think.

For him, humans may find evidence of simple life on Mars or natural satellites of various planets within the next 10 to 30 years. The signs, according to the 57-year-old woman, would be more like microbes or algae, instead of robotic aliens or super-sophisticated life.

Ellen's words were actually being worked out by astrobiologists. They are observing various exoplanets in search of gas contents that might be produced by creatures like microbes.

In addition, there is also the possibility that there is a microscopic life on a number of natural satellites belonging to Jupiter (Europa, Ganymede, and Callisto) and Saturn (Titan and Enceladus).
