Because the laws of physics are the same everywhere, aliens resemble humans

The public has seen numerous exotic visuals thanks to world cinema. As well as the humanoid from Spielberg’s ET, Leeloo from The Fifth Element, Neytiri from Avatar, and the humanoid lizard from the film Signs have all been portrayed.

But how do a̳l̳i̳e̳n̳s seem in real life? Scientists have some quite logical theories on this subject.

According to researchers, the rules of the cosmos really severely restrict outward variety. In his book “The Equations of Living: How Physics Shapes Evolution,” astrobiologist and University of Edinburgh professor Charles Cockell lists three rules that all life forms, without exception, must abide by.

The same physical laws apply everywhere. For instance, the gravitational force is present both inside and beyond the solar system.

Everywhere, the prerequisites for the existence of organic molecules are the same. Organic molecules on Earth and in other planetary systems degrade at high temperatures and stop functioning at low ones.

The same components will be used by life elsewhere in the cosmos. Water is the optimum fluid for the movement of carbon, which is the best chemical element for the emergence of life.

What does this actually mean? We are aware that matter may exist in three different aggregate states: solid, liquid, and gaseous. Additionally, if a̳l̳i̳e̳n̳s live in gas, they must abide by the rules of aerodynamics.

The same manner pterodactyls did, paper airplanes, sparrows, and dragonflies followed these guidelines. The a̳l̳i̳e̳n̳s must have an extended, streamlined bodily form if the brothers in question are aquatic since they are susceptible to the principles of hydrodynamics and hydrostatics (the law of Archimedes in particular).

Living on a hard surface necessitates the use of limbs (paws, legs, and arms) to decrease friction. Alternately, move like a snake, which can survive without limbs. As a result, the a̳l̳i̳e̳n̳s’ structural similarities to Earth’s population are plausible.

Can we expect sensory organs in a̳l̳i̳e̳n̳s? According to Dirk Schulze-Makuch of the Technical University of Berlin, head of the German Astrobiological Society, it relies on the surroundings.

If there is no way to transmit sound waves, who needs ears? Almost all living things on our planet have evolved light-sensitive organs; vision may take many different forms, from the intricate fly eye to the stereo vision of a person. However, if a̳l̳i̳e̳n̳s dwell in environments where light cannot enter, they could not require eyes.

The majority of experts concur that if humans make contact with a̳l̳i̳e̳n̳ intelligence, we will have to deal with predators. Additionally, there aren’t any known instances of intelligent plants or fungus on Earth.

It just doesn’t make sense for a stationary creature to increase its pace of responses and use energy to keep its metabolism at a high level. Although the human brain only makes up 2% of the body’s bulk and uses 25% of its energy, the intellect is nonetheless a costly pleasure.

One cannot afford such a luxury for everyone. Only when a living thing needs to get food or avoid becoming food does the brain start to pay off.

So why aren’t a̳l̳i̳e̳n̳s able to be descended from herbivores? The truth is that compared to other animal diets, plant foods are less energizing. Because they would spend a lot of time consuming low-calorie plant foods, intelligent herbivores would find it challenging to grow intelligent. From this perspective, carnivorous animals have significantly more time between meals.

There is also a definite hierarchy among the predators: if the lion must be smarter than the antelope, then the wolf must be smarter than the lion as he hunts in a pack and must learn to work well with his fellow h̳u̳n̳t̳e̳r̳s̳.

Therefore, it is most likely that the a̳l̳i̳e̳n̳s we will encounter were once a pack of predators (unless, of course, we are the only species in the universe). Because of this, a lot of scientists are skeptical about efforts to make contact with a̳l̳i̳e̳n̳ intelligence.

It is doubtful that visitors from the area will be mirror images of ourselves, though. The tuning that is popular in our solar system—a huge head, a nose over the mouth—is probably unimportant elsewhere in the cosmos.

Some inventors choose the other path, even on Earth. Dr. Dirk Schulze-Makuch recalled that, for instance, neurons in octopuses are dispersed throughout the body, including the tentacles, and that only a small portion of the brain is located in the head.

Birds have developed a highly helpful trait in an effort to minimize their flying mass: their brains are packed with neurons far more densely than those of humans. By relying on an apparently trustworthy measure like the head to body weight ratio, we undervalue their intellect.

The New Caledonian crows, meanwhile, possess the ability to not only utilize tools but also to make them from scratch. They are not less intelligent than primates, either.

Finally, a̳l̳i̳e̳n̳s could not merely be a product of nature but also a result of a technological symbiosis.

According to Dirk Schulze-Makuch, “people have already integrated technological gadgets like pacemakers, contact lenses, and other prostheses into their bodies.”

“A̳l̳i̳e̳n̳s are more than capable of going one step farther and transforming into cyborgs.

They can, for instance, put the brain inside of an electronic-mechanical shell to get beyond the natural restrictions on the longevity of biological bodies.

And if you asked me to describe the appearance of a̳l̳i̳e̳n̳s, I would suggest that the most sophisticated ones would be entirely automated.
