How does alien look-like

Whatever image we have of the size and type of the alien is in the films of Hollywood. Various Hollywood films such as MiB, Alien, Species, etc. have depicted most of the parasites in the shape of humans or as insects. Seeing these films, the same form of paragrio has settled in our minds.

The symmetry of extraterrestrial life

Using the laws of physics, biology, and chemistry, scientists have tried to predict what alien creatures might look like. Newton was surprised that all the creatures he sees around him all have bilateral symmetries, two eyes, two arms and two legs in one symmetry! Is it accidental or God's work?

Zoologists believe that during the Cambrian explosion half a billion years ago, nature had created many developing species of small size. During this time, nature had done many experiments with biological symmetry. Some of these also had spine sizes of X, Y or Z. Some also had symmetry like starfish. A creature that had an I-like spine and bilateral symmetry is the ancestor of most mammals today. Some animals of this experiment went extinct and some still remain. Hollywood filmmakers show the same shape as human beings with bilateral symmetry as extraterrestrial beings of space, but this is not necessary for all intelligent beings. Extraterrestrial life can be in some other symmetry.

Some zoologists believe that during the Cambrian explosion, a variety of animal shapes originated as a competition between hunter and prey. The emergence of multicellular life, which first made food for other living beings, gave impetus to the gradual development of both those lives, in which every life was competing to be better than the other. It was in the Cold War RA was like a competition between the US and the Soviet Union, in which both sides were engaged in leaving each other behind.

Properties required for intelligent life

By studying the origin and development of life, we can make a list of the essential properties for intelligent life. The following qualities will be necessary for intelligent life

1. Eyes or some kind of nervous system to feel the environment.
2. Thumb-claw
3. Communication system like speech power

These three characteristics are necessary to realize and use the environment, which is the hallmark of intelligence. But in addition to these three mandatory features, there can also be features that are not mandatory. It does not include shape, form or symmetry, intelligent life can be of any shape, type, and symmetry. The alien organism is not necessarily the same size as that shown in TV and films. Child-like, insect-eyed supernatural that we see on TV and films is similar to that of the class of 1950 B-grade films, which is still rooted in our inner self.

Why do humans have more intelligence than need?

Some anthropologists have added a fourth characteristic to intelligent life in this list which explains a wonderful fact; Man is more intelligent than the intelligence required to maintain his existence in the forest. Adi lived in a forest, he needed to hunt for a living and fast to protect. For this, the human mind is much more powerful than it needs intelligence. The human brain can measure the depths of space, understand the quantum theory and possess advanced mathematical knowledge; It is unnecessary for hunting in the forest and for its rescue. Why this extra intelligence?

In nature, we see some cheetahs or gazelle-like creatures who have more capacity than necessary to save their existence, because we see competition among them. Similarly, biologists believe that a fourth characteristic, a 'biological competition' is developing the intelligence of humans. Perhaps this event is from another human of its own species.

Think about the wonderfully diverse universe. For example, if someone choons for a few millions of years and increase the lineage of the octopus, then they might also become wise. (We were separated from the monkey species six million years ago. Because perhaps we were not able to adapt to the challenging changing environment of Africa. In contrast, the octopus is adaptable to live under the rock, so it does not develop in millions of years. Has been found.) Biochemist Clifford Peak over says.

"When they see strangely hard-edged sea creatures, jellyfish with tentacles, bisexual worms, they think that God has a unique sense of humor. And we will also see this sense in other planets of the universe."

Yet Hollywood is right when it shows carnivores to alien beings. Non-vegetarians are guaranteed for success on Boxophys, but there is a truth hidden in it. Hunters are generally wiser than their prey. The hunter has to plan, chase, hide and fight the hunt for the hunt. The fox, dog, lion, and have their eyes forward to snap their prey before guessing their distance from it. With two eyes to see the prey across them, one gets the three-dimensional vision. Hunting such as deer and rabbits only know how to run, their eyes are on the side of their faces so that they can see the predator around them in 360 degrees.

In other words, intelligent life in space can have eyes or some kind of nervous system on the front of the face like a predator. They may have aggressive, carnivorous and terrestrial traits and behavior of foxes, lions, and humans. But it is also possible that their life is based on different DNA and protein molecules, they have no interest in eating or living with us.

Alien Size

From physics, we can also estimate their body size. Assuming that they live on a planet the size of the Earth and that their density is similar to the density of water (like the creatures of the Earth), the size of alien creatures will be the same as the Earth's creatures. Due to the principle of proportion, a giant shaped creature like Qingkang or Gadjila is not possible. According to the principle of proportion, the laws of physics change radically by increasing the size of an object.
