How is it possible to discover extraterrestrial intelligent life?

At present, the means of human beings to find extraterrestrial intelligent beings are electromagnetic wave signals and space drifting boxes, not astronomical telescopes, astronomical telescopes only look at the light phenomena of celestial bodies, how can they see life, it is true, the universe is huge, and human beings are already very weak to observe the Milky Way alone, let alone the outer galaxy.

Of course, we think that the current human search for extraterrestrial intelligence is only tentatively named, what does that mean? It's that we're sending electromagnetic signals now, and when they reach some intelligent creature hundreds of millions of years from now, we'll know that there's a human being on the other side of the universe, and that's it.

Now that human beings haven't even flown out of the solar system, it's unrealistic to explore the wisdom of the universe, and the reason is that the level of technology is low.

The relationship between the distance of the universe and the speed of light is very close, and according to the current human understanding, light is the medium of speed and time, below the speed of light, time growth is equal to the speed of light, time stops, is greater than the speed of light, and time flows backwards.

Personally, I think that although Einstein was a genius who developed the theory of speed, but at present, many theories have surpassed Einstein's theory of the universe, and Einstein is a man after all, or a man, and he said that light cannot be surpassed, and I think it is worth rigorously debating, so it is very likely that the speed of light can be surpassed, but the level of human technology is not enough.

So, imagine how much time it will take between the present and the time when humanity can build a cosmic kingdom? The timing is unknown, but based on the current level of scientific and technological development, it will not take hundreds of years.

lz said that human beings are already highly civilized, I think one-sided, for ancient times, it is highly civilized, it is good, for the future, it is ancient again, at present, whether it is human society or human technology, it is quite backward, what do you refer to? It is to look at the overall strength of human beings in terms of the scope of the universe and the scope of expansion, the universe is so big, there are so many celestial bodies, and human beings have only explored a few large footprints in the solar system, and they have only reached the moon, and they have not yet expanded to the moon, so we can know that human beings are in the beginning of the universe.

Oh, yes, the space drift box is not a strict name for an object, and by drift box, I mean that the carriers of human information, such as drawings and instruments, are put into a special box, and then sent to the universe to drift at will, and humans have done this before, so I call it the drifting box, and if it has a fixed name, I apologize.

As I said above, although in the universe there is a large base of distance and time, I think that if science and technology are high enough, at a speed that surpasses the current level of science and technology and practical theory, I believe that the concept of time of hundreds of millions of years and the concept of distance of hundreds of millions of light years will be easily overcome, so it is meaningless to lament the inaccessibility of time and distance now.

Yes, you're right, but humans have been around for millions of years, not tens of thousands.

The fastest speed in the universe is light, and Einstein said that the speed of light cannot be exceeded, and that time stops when the speed of light is reached. I also have a question, how to determine the time of light? Yes or no, what is the energy consumption of light quanta, light quantum is a fictitious concept, so what is the nature of light.

When exploring extraterrestrial life, the possibility of life can be judged according to the following two points:

1.The cosmic environment surrounding the planet. For example, whether the light and heat of the star are sufficient to maintain the appropriate temperature, whether it is in a safe area (asteroid collision events rarely occur), etc.

2.The material composition of the planet. For example, water (the medium of life metabolism), atmosphere (isolating stellar radiation and protecting the structure of life from destruction), organic molecules (the material basis of life), etc.

Generally, it can be determined by indirect molecular & elemental detection methods, i.e., by analyzing elemental spectra and the like.

In general, if the environmental conditions are suitable, liquid water is present, and a large number of organic molecules are present, then it can be judged that life is possible on the planet.

Of course, this is only a possibility, after all, the evolution of life is much longer and more complex. So far, scientists have only simulated the transformation of inorganic molecules into organic macromolecules under laboratory conditions, and how life is born from organic macromolecules remains to be studied.

Otherwise. When the aliens can't stand the aliens, they come to us, and then we will discover the extraterrestrial intelligent life.

I think it would be unwise to launch a "space driftbox".

Extraterrestrial life is not necessarily human, it is undoubtedly appropriate, human beings are only biological species on the earth, because human beings are produced according to environmental elements such as the earth's ambient air, key components, and gravitational fields, and are suitable for survival on the earth. Extraterrestrial life may be highly intelligent or low. If people are fortunate enough to discover the first extraterrestrial life, it is likely to be lower life, because most of the research results at this stage are focused on the scientific study of radical life patterns.

For example, researchers have studied the DNA of microorganisms in the surface soil layer in Antarctica's harsh natural environment, and reconstructed the genes of 23 of them, including two groups of pathogens that had never been detected before, and obtained the first genes such as WPS-2 and AD3. Biologists have found that key populations in the soil layer have unique genes that make them highly susceptible to radon and carbon monoxide, allowing them to obtain these small amounts of vapor from the air at a sufficiently high rate to maintain estimated energy levels** and be suitable for intermediate and intermediate manufacturing. This suggests that in the original Arctic Gobi, there were no vascular plants, but there was still life, and how life survived in a nutrient-deficient natural environment like the Antarctic continent is an interesting study, revealing the probability that air vapor is suitable for other extraterrestrial life.

Since most organisms use sunlight or the kinetic energy of the soil layer to grow and develop, experts suggest that a great deal of scientific research is needed to see if the behavior of organisms, which are based on air vapor as kinetic energy, is more widespread in Antarctica and other regions. It can be seen that if people are lucky enough to discover the first extraterrestrial life, it is likely to be a lower life in an extreme natural environment.

And the cosmic space of everyone's daily life is indeed too large, and the probability of other life is very high, scientists deduce that there are at least 100,000 life-only stars in the solar system alone, so there is no doubt that there are high-level intelligent life, and there are also low-level life civilization behaviors, and high-level life is not as big as people depict, agile limbs, I think the characteristics of this part or a little very likely, so how is the other part? I think this is unthinkable, because the living conditions of this kind of civilized behavior, such as force, temperature, environmental humidity, and the composition of the air, are very different, so this difference in factors must also make the shape of extraterrestrial life somewhat different.

It's true, because the rate of evolution of life on each planet is not the same, and not necessarily all planets have humans, so it's true.

This is true, there is no scientific basis for aliens at all, but there are some signs of life in aliens, so it may be some intelligent creatures.

This is also possible, because there are many planets in the universe, and the ecological environment is also different from the earth, and it is very likely that there will be advanced intelligent beings.

There may be many forms of life in the universe. Our current definition of life is: That is, the phenomena of self-growth, reproduction, feeling, consciousness, will, evolution and interaction, including the amino acid structure that can be replicated by biochemical reactions, as well as fungi, bacteria, plants, animals (humans), and others will artificially send a phenomenon with a certain connotation in line with the basic attributes of life into the category of life, including hybrids, artificial intelligence robots with pure free will, etc.

<> and when we look at the universe on a larger scale, life may be different, and life may take shape beyond what we currently imagine. Take the earth human beings as an example, everything is designed according to the original materials of the earth human beings, eating, wearing, using, playing, etc., through practice, some are reasonable and perfect, but I am not close, some people are alive, not forever, such as human height, almost not long, human teeth, only one mouthful, falling, and people's **, beautiful when young, wrinkles when old, yellow, etc., although human beings are not satisfied with these, but there is no good way for the time being.

There are some ways, but we must achieve advanced civilization and use high-tech means to create the achievements that human beings need most, in order to solve the shortcomings of human beings, meet the needs of human beings, and finally start interstellar travel and fly out of the galaxy, why fly out of the galaxy, because it has not yet been discovered that there are aliens in the solar system, there is life, and it may be as long as human beings, because they belong to the solar system. The Earth and the solar system we live in are actually very small in the universe, and the number of stars and planets in the universe is staggering.

So big that somewhere in the universe there may be planets that are very similar to Earth, and there is a good chance that such planets will support creatures closer to us. But this probability is still relatively small. The biological form of the virus may have existed since the beginning of the earth's existence, and it coexists with the host in its simplest and most efficient form, and constantly adapts to the new environment through its own adaptive mutation.

We can't look at extraterrestrial creatures, especially intelligent life, from the perspective of earthlings, who may be able to survive without oxygen, without food, and only replenished by special energy.

At present, human scientific research has not found extraterrestrial life, and the Earth is still the only planet with new human figures. As for whether aliens are highly intelligent creatures, it is uncertain.

Life produces advanced intelligence, there is no growth and resilience system, there is no specific excitation conditions from the outside world, and its evolution process cannot be realized with a single or lack of a certain condition, and life produces advanced intelligence, which is not inevitable, but a single and accidental event, and life on earth has also proved this. The universe or intelligent life is almost zero.

Aliens must be humans. But extraterrestrial life is not equal to intelligent life.

Human beings are the name of the earth, and they should be called high-level intelligent beings.

I think such a claim is possible because there is no direct evidence at the moment.

There are people outside the world, and there is a sky outside the sky!

I'm not sure there is, just hear from you.
