Aliens, if they exist, are probably huge. At least this is the conclusion of a new work by cosmologist Fergus Simpson, who estimated that the average intelligent extraterrestrial weight would be 300 pounds or more. The ET (the film of the same name) would be tiny compared to these interstellar giants.
His argument is based on a mathematical model, which assumes that the organisms on other planets follow the same energy conservation laws we see here on Earth - that is, the larger animals need more resources and spend more energy, so are less plentiful. There are many small ants, for example, but much less whales and elephants. Thus, throughout the universe, as is the case on Earth, there is probably smaller than large animals, says Simpson, a scientist at the University of Barcelona in absolutely spain. Since we know the number of planets inhabited by small animals would be much greater than the amount worlds where large predominate, so it's very likely that we are on a planet relatively small animals - and are probably one of the smaller intelligent beings, he said. Simpson says that certain minimum size is probably necessary for intelligent life, and he used a range of different sizes of bodies found in animals on Earth to reach a more likely distribution of organisms on other planets.
"I think the average size calculation is reasonable" This word was said by Mr. Duncan Forgan, one scientists from the School of Physics and Astronomy, University of St. Andres, who had no part in the work, which was published on arXiv.org site.
However, there are many factors that the calculations do not take into consideration, Said Mr. Forgan, partly because it is simply not plausible to do so. Simpson's work "does not address the correlation between body mass and the gravity of the planet's surface" for example, that Mr. Forgan said okay? It is expected that the planets with stronger gravitational force have smaller animals; a tiny planet with low gravity, you might expect the opposite. However, in total, taking this weird thing into account, "Could push the average down, a little size, but it's hard to say without a more accurate calculation," Forgan said.
Seth Shostak, a researcher SETI Institute, said the work reminded him of another previous work he had done, suggesting that any aliens we could possibly find tend to be large, since the larger animals live longer, and bodies with longer life are more likely to develop the kind of technology needed to make contact with humans.
However bro, this weird work and the Simpson, it is only still speculation. Fascinating and fun thing, but still speculation. "It iis interesting, but there are really is no hard data to work with" He said like this "We only have our planet and its inhabitants to serve as models of what life looks like. This work, like the others, assumes that the earth is "typical" or a planet in the average. and uses the information here to assume about the unknown. But what is impossible to know, if it is appropriate to do from a scientific point. Well it's a weird thing isn't? The work also did not take into account any kind of evolutionary theories, Shostak said (which, to be fair, even may be plausible in this type of calculation). Despite the larger animals tend generally to be smarter than the small, everything is relative - we are not, of course, the largest organization in the world. In fact, it was our opposable thumb and upright posture - not our body mass - which allowed our flourish intelligence, That what Mr. Shostak said.
"Polar bears are great, but do not write literature, or build radio towers," Shostak said with his laughing "and much of this is probably due to the fact, that they walk around on all fours."
