5 theories about how the aliens look like (if they exist)

People love to fantasize on the topic of aliens - talking about it numerous feature films. Aliens in them take many forms - from formless slugs to complexly organized humanoids. There is also a scientific approach to the problem: scientists predict, will look like forms of life, which, in theory, a person can get in touch. Before you - 5 of forecasts.

1. Meduzy

Dr. Maggie Aderin-Pocock said that, most likely, we will meet aliens, structurally resembling marine organisms: to communicate, they will use pulses of light and nutrients that are essential for growth and reproduction, will be absorbed from the air through a kind of "mouth space ».

Maggie's theory is based on the fact that terrestrial life first originated in the ocean, and an alien evolution could go the same way, only instead of water habitat would serve the atmosphere of another planet.

2. Tarakany

Ironically, one of the forms of life existing on other planets, it can be the cockroaches: the structure of the body allows you to adapt to different conditions, including the effects of a nuclear explosion. Millions of years of development of these insects show that the roaches quite able to live in an environment far from the earth.

3. Primates

Simon Conway Morris, a professor at Cambridge University, dealing with the problems of Evolutionary Paleobiology, claims that aliens are like people, not only in the physical structure, but also on the moral qualities: "The propensity to violence, greed, and optionally may well be inherent visitors from distant galaxies - states Morris. - Darwin's theory of evolution is universal, that will help us, if anything, to make contact with other civilizations ».

In other words, if humans and the aliens show up the same character traits and weaknesses, it is only contribute to mutual understanding.

4. Inorganic forms zhizni

Many researchers such as Morris believe that alien life forms similar to Earth, but even in 2010, scientists were found multicellular organisms do not need oxygen. This information can flip our understanding of organic life - more and more biologists say about the possibility of inorganic life, as in nature, there are many other "building materials." In conditions other than Earth, could arise organisms used in the process of life, such as phosphorus, sulfur and other chemical compounds.

5. Residents of the ocean depths and higher layers atmosfery

Lewis Dartel, astrobiologist from London, said that the evolution of life on other planets occurred under the influence of factors similar to Earth. For example, "water" worlds of the people look like animals, living in the depths of our oceans, and on a planet with a thick atmosphere of greater chance of finding beings traveling by air.
