Why impose the conditions of human existence on aliens

Absurd. Questioning without understanding clearly.

The basic composition of the human body is C h O, especially C, which can form a large structure, and the lighter mass also guarantees that it will not collapse due to its large size.

Similar to C is silicon, but the mass of silicon will be quite large, and the huge mass that makes up a human body is unimaginable.

Water is HO, sunlight promotes plant growth i.e. c, and atmosphere is O.

Therefore, scientists are looking for life forms that exist in the cho way, rather than copying the Earth's environment to outer space.

Hehe, indeed. The order of the periodic table is arranged by the number of protons, from 1 helium to more than 200 rare elements, without missing a single one. In other words, most of the elements found in the universe in the future, except for some rare elements of extremely high quality, will be isotopes of existing elements.

Has humanity discovered all the elements in the universe?

We live on Earth, and the Earth is just a tiny speck of dust in the vast universe, so many scientists wonder if there will be a planet like Earth, and whether there will be life on those planets. As a result, many scientists use human living conditions as a reference to find aliens, but the approach of scientists has made many netizens difficult to understand, let's take a look at what is going on.

Some netizens said that one of the reasons why he expressed incomprehension of the behavior of "scientists looking for aliens according to the way of human existence" was the particularity of human beings. Even on the earth, there is almost no other creature like humans, so in the universe, it is even more difficult to find a planet that is exactly the same as the earth, let alone a creature like a human。Therefore, it may be a little unsatisfactory to look for aliens according to the way people live.

Secondly, some netizens also indicated thatThere are still many questions and secrets about the mysteries of life on Earth, and human beings are still exploring them, so why can scientists be so sure that the way alien creatures survive must be similar to humans? Many netizens are skeptical that scientists use human living conditions as a reference for searching for aliens.

In fact, the reason why scientists use human living conditions as a reference for finding aliensCommonalities are mainly found in different kinds of terrestrial organisms.

For example, all organisms need to maintain a certain body temperature to survive, and all organisms need oxygen and water to surviveEven fish on the bottom of the sea need oxygen, but the organs they use to absorb oxygen are different from those of our terrestrial organisms. Therefore, in fact, it is understandable for scientists to use human living conditions as a reference for searching for aliens.

I think maybe netizens think that the living conditions of aliens are not based on the living conditions of human beings.

The conditions for human beings not necessarily to survive on extraterrestrial creatures.

Because netizens think that this way of reference by scientists is not scientific, nor comprehensive, and somewhat arbitrary.

Because many netizens think it's unlikely.

What if aliens don't need oxygen? In fact, the vision is still different.

Just like why the god in the minds of black people is black, the god in the hearts of white people is white.

I also don't think so, because the alien environment is not certain.

Because netizens may have watched too many sci-fi movies and thought that there were indeed different kinds of aliens.

Because netizens must think that the scientist's idea is impossible to realize.

For extraterrestrial life, especially advanced life similar to humans, it should exist from the current theoretical calculations and in people's imagination. However, as far as the current level of human science and technology is concerned, there is neither a way to confirm nor a reason to deny it. And they may be completely different from us in morphology and structure, because life on Earth is based on carbon, and on other planets, the existence of silicon-based life cannot be ruled out.

If this is the case, then the characteristics and living environment of silicon life forms are unimaginable to us, such as 200 degrees Celsius, 10 atmospheres and methane rivers are suitable environment, let alone imagine what they will look like. One thing is for sure, though, they should have eyes, fingers, and feet.

Even if there is really extraterrestrial life on Earth, we may not be able to talk to them, or even be unaware of them, because they must have a level of technology hundreds or thousands of years more advanced than us in order to cross such a long distance in space, and we have to assume that such a law does exist in the universe. As far as we are concerned, it is now far from a question of whether it can be done in practice, but whether the theory is valid. None of our existing edge sciences, whether string theory or membrane theory, can prove that space-time can be traversed, but only speculate that it is possible.

In addition, there is a constraint on the natural lifespan of a living organism. A few decades ago, people learned the theory of crystal management, perhaps they were senior engineers; Now VLSI circuits have become commonplace (the graphics card GPU I use now integrates 1.9 billion transistors), and to master these theories and technologies, people still have to start learning from 1+1, ABCD, and Ohm's law when they are young. Therefore, it is likely that at some point, people will have mastered theories to the point where most people cannot master them from elementary school to old age.

At that time, unless the life span of human beings is greatly extended, or the intelligence of human beings is greatly improved, or a coil is put on the head as described in some science fiction, the knowledge of predecessors can be instantly entered into the brain. Otherwise, technological progress will be limited by the natural lifespan of life, and of course the same is true for extraterrestrial life.

In addition, the lifespan of the planet also limits the development of intelligent life, and if human beings are unable to leave the earth to live freely in the universe by the time the sun runs out of fuel (or when the earth experiences an ecological catastrophe), the development of this group of life in the solar system will also end. Therefore, there is a possibility that the advanced life forms in the universe do exist, but no one can develop to the point of leaving their own planet, and no one can prove the existence of others.

Therefore, it is impossible to prove the existence of extraterrestrial life, especially human-like advanced life, at present, and it is unknown whether it can be solved in the future. In some ways, it's not all human to say.

As for the discovery of humanoid skulls on Mars, it is certainly not true, and there have been no such discoveries yet.

Probabilistic things are of course and they are inevitable, and they are extremely numerous1 or very primitive, such as bacteria and algae.

2. Either it's about the same as us, or it's not much stronger, in short, technology can't break through, transcend space and time, and can only always guess and wait and see each other like now, or all civilizations will never be able to break through this, and will never be able to get in touch.

3. Either the technology and civilization are so much more than you can imagine, just like when you look down at ants or study ants, they are completely unaware of your existence, even if it's just 1 millimeter next to them, and some friends will say, Then why don't they try to communicate with us, have you tried to communicate with ants, do you have antennae, and transcendence does not mean that it is compatible.

4 Or, as Hawking describes, it's another incomprehensible form of life, like silicon or something, and you don't think he's a living being, and he's living in an environment that people can't live in, and they think the environment on Earth is horrible.

There will definitely be life forms, I firmly believe.

Because all life has the ability to adapt to the conditions of existence, which is the basis of the theory of evolution.

As for what Hawking thinks, I don't know.

And now more and more extraterrestrial flying saucers are discovered, which can prove the existence of extraterrestrial life, but the country does not release too many details for the sake of stability.

There must be, but so far I haven't found it in the vicinity, and I can't say that the ** rate of our earth is too low in the vast universe.

Anything is possible, just beyond my imagination.

Different life forms depend on different substances to survive ...
