Outside of our solar system there are many planets. The vast majority of them are unsuitable for life. But surely among them there are those on which there may exist living things. That is, aliens. They may look like whatever. In this regard, scientists have already put forward a lot of assumptions and hypotheses. However, no one from the scientific community has yet the goal is to calculate the average weight of alien creatures.
The pioneer in this direction was Fergus Simpson, who works at a university in Barcelona. According to his approximate According to estimates, an alien should weigh about 300 kg.
However, confine oneself only to rough estimates Fergus Simpson did not. He conducted a complex research work, guided by a special model that is based on Bayesian statistics. Simply put, the basis of his work lay Bayes theorem of the same name.
According to Fergus Simpson, the scientific community is mistaken opinion. Like, representatives of extraterrestrial civilization should look a bit like a person. But this, in his deep conviction, far from it. After all, taking into account the variety of planets that are in space, it is safe to say that aliens are not like humans. And not only externally, but and intellectually.
Simpson’s calculations are based on the assumption that in all The universe there are permissible minimum dimensions by which absolutely any life form must possess. This is a guarantee successful development of their intellectual abilities. Nonetheless, the scientist’s work does not take into account the so-called the adjustment between body weight and gravity that exists on one or another planet. That is, it does not take into account the effect of gravity on dimensions, mass and height of the inhabitants of the planet. After all, on those planets where gravity is strong, small life forms should dwell. What concerns small planets where the level of gravity is extremely low, then there should be a completely opposite picture.
Duncan Forgan, who teaches at the University of St. Andrews, believes that calculating the average size seems to be the most rational, since there are many factors that were ignored during the calculation. However, this is not Simpson’s fault. IN As part of his work, he did everything possible.
And here is Seth Shostak, who heads the SETI Institute, take the opposite view of Simpson’s work. is he stated that the work of his colleague was certainly interesting, but not Moreover. After all, it does not provide any specific data and facts.
By the way, the latest data that NASA satellite transmitted to Earth Kepler reports that billions of stars in The Milky Way, have an average of 1-3 planets in the habitable zone. By time, the telescope has already found about 1 thousand planets around the stars in our Galaxy and about 3 thousand potential candidates for their role.
