How many aliens are there in the universe and are there aliens in the universe?

If you don't find it, it doesn't mean that you don't, you know how limited the current means of observation are for human beings, do you think you can see the situation on other planets with astronomical telescopes? Far from it. It is difficult for human beings to even find planets at present, although some have been discovered, but compared with the number of planets in the universe, even a grain of sand in the desert is not as good, in such a vast universe, the earth is not special, so I am sure that there is life in other places.

It's just that there's no way to spot them at the moment. In addition, most of the flying saucers are fake, and a very small number are not necessarily real, but no evidence has been found to prove it. Many flying saucers** are fake, or meteorological phenomena, or man-made.

Whether human beings can fly to the depths of the universe to explore other regions depends on whether lightspeed technology can make major breakthroughs. If there is no way to travel faster than the speed of light, then interstellar travel will always be a dream. Flying below the speed of light, it takes tens of thousands of years to fly to the nearest solar system, and no one has that long life to wait.

Alien? You know, there's a place called Black Triangle, and those people say it's alien-controlled, airplanes. Person. Boat. Radar, these things will go to **, and if they don't go back, the radar will fail, and all the 'aliens' who haven't solved this mystery yet

Are there any aliens in the universe?

There are no aliens in the universe.

Since the exploration of extraterrestrial life by human beings, no footprints of extraterrestrial life have been found, let alone aliens, if they really exist, it will be a sensational event around the world, and it is obvious that whether everyone speculates or speculates, in fact, the result is the same "no evidence".

But science is all about evidence, and since there is no evidence of aliens found today, it must be "no", so from the perspective of existing science, it is no, and this does not need to be disputed.

Although there will be aliens in the universe, modern astronomical observations have ruled out the possibility of aliens in the solar system, and they will enter interstellar space in light years, which is a distant distance that is difficult for us humans or other intelligent beings to conquer.

The universe refers to matter and space-time.

The mainstream view in modern cosmology is that the origin of the universe originated from a large **, which evolved from a state of extremely dense and extremely high temperature in the past, and reached a state through continuous expansion, which is called the grand theory of the universe or the theory of the singularity.

We don't know what caused this big **. The light emitted by the big ** is still spreading outward. The resulting gases and clouds, dancing, spinning, and aggregating into embryonic galaxies.

The universe is a general term for the vast expanse of space and the various celestial bodies that exist in it, as well as the diffuse matter. The origin of the universe is an extremely complex issue. Modern astronomical observations prove that it is in constant motion and development.

For thousands of years, scientists have been searching for when and how the universe came to be. Many scientists believe that the universe was formed by a large ** that occurred about 14 billion years ago.

Probably, because there are too many planets similar to the earth, then there must be creatures similar to humans in the universe, and the UFO phenomenon is the most exciting and far-reaching event of this century. Some of the UFO phenomena that seem to violate the laws of nature are most likely the prelude to a revolution in modern physics, because the major discoveries in physics in history often begin with the observation of the sky, and the UFO phenomenon may also be related to extraterrestrial intelligence. The various functions it shows that go beyond the level of modern science and technology are undoubtedly a great challenge to human wisdom and today's science and technology.

The latest reports say that there are aliens in the universe.

Is there really any other life beyond Earth?

It's a must.

China-Singapore Zhejiang Network, October 24 According to foreign ** reports, British experts believe that we are not alone in the universe, and there may be as many as 40,000 highly developed civilizations in the galaxy where we are located. So far, no one has been able to successfully detect whether there are signs of life beyond Earth. However, there are enough skeptics who are skeptical that these highly developed extraterrestrial civilizations exist right on our planet.

Of course, this is more of a philosophical discussion. In any case, simply accepting that "humans" exist may not be the whole thing we have to discover and explore the universe. Duncan Fogan, a researcher at the Edinburgh Observatory in the United Kingdom, has tried to simulate a number of different scenarios to show the Milky Way in which we live.

To do this, he made use of all the information about alien galaxies that had been obtained in recent years, as well as all the information about alien planets that had been made public during this period – chemical composition, number and characteristics. After comparing various scenarios, Fogen concluded that there may be 300 to 40,000 highly developed civilization camps in the Milky Way, and that it is highly likely that they have established a connection with Earth. Historically, the most famous Drake formula encouraged all sorts of speculation and discussion nearly half a century ago, opening up a great discussion of a pluralistic habitable world.

In 1961, at the age of 31, Frank Drake, an astronomer at the University of California, invented an equation for estimating the number of extraterrestrial civilizations, which is the famous "Green Bank Formula": n=r* fp ne fl fi fc l. This formula seems a bit complicated, and it uses the product of a series of possibilities to calculate how many civilizations might exist in our galaxy.

We can't calculate l and fc, so scientists disagree about the value of n. Carl Sagan calculated that for every 1 million stars in the Milky Way, there is a highly developed extraterrestrial civilization, and he calculated that there is a civilized planet for every 100,000 stars. However, some people have raised doubts about this extraterrestrial civilization equation, thus denying that there are developed civilizations in the galaxy besides Earth.

For example, Shukrosky of the former Soviet Union believed that other planets have nuclear ** and will be destroyed by nuclear war, so the lifespan of developed civilizations is very short, and there may be no other civilization in the galaxy except the earth. Another opinion is that the value of equation ** is too much and is unreliable. For example, the American astronomer McKale Hart believes that if there were developed civilizations in the Milky Way, then it would have colonized the Milky Way and so on, and it is impossible that we have not discovered it so far.

This suggests that there are no other civilizations within the galaxy other than Earth, and that life may exist outside the galaxy. However, British experts pointed out that all conclusions of one kind or another are only based on speculation, and in fact, we do not know this kind of speculation ourselves, and go to ** to find extraterrestrial life. The actual situation is the same as before, it is only known that "they" are nearby.

Friends, you've watched too many sci-fi movies, how big the universe is is a mystery, and there is no conclusive evidence of aliens so far, but something is for sure, the problem is that how many planets suitable for life are unknown, so how many aliens are unknown.

You can enrich your imagination before discovering it.

It is unknown whether aliens exist, but the universe is so big that there may be aliens.

There are no aliens, there is no 100% seeing, so the scientific community will not admit the existence of aliens.

But just think about the size of the universe, the age of the universe, the age of the earth, the age of humanity, and you will find that it would be inconceivable if there were only us in the universe and no extraterrestrial life.

According to probability, the possibility of life in the universe is very high!!

The Milky Way, to which the Earth belongs, is made up of between 200 billion and 300 billion stars and nebulae.

Confirm the Encyclopedia].

There are countless galaxies in the universe that resemble the Milky Way. Today's geoscientists say there are about 100 billion galaxies in the universe, but this number will continue to increase as measuring instruments become available.

If there is only one planet in the Milky Way like Earth, then there are hundreds of thousands of aliens.

This is calculated with the lowest probability, and if there are two planets like Earth in a galaxy, the number of aliens will also triple.

Thinking that even if there are aliens, it is impossible to fly to the earth) is to think that the technological level of aliens is about the same as that of the earth, and you are sure that the technology of the earth is the most advanced in the universe?

And don't use our modern science and technology to speculate on the science and technology of aliens, the distance of space is unimaginable in our eyes tens of thousands of light years, but it does not mean that there is no technology to achieve interstellar travel! Space folding, time tunnels, I've heard of them, although these are not realized now, but theoretically give us a direction for long-distance and short-term time travel!

People 100 years ago would not have imagined how much time it takes to get from Beijing to Shanghai today! You won't think about how much time it will take to get from Earth to Mars in 100 years, and you won't think about how long it will take to get from Earth to another living planet in n years! Just imagine that by that time, on that planet"Person. "If we only have our technology now, will they also have the idea of the landlord?

Interesting, isn't it?

Yes It's far away from another galaxy that we haven't discovered yet. There may also be a group of "cosmic people" who have joy, pain, and love. Would you also like to have aliens?

At present, there are many cases of alien discovery on Earth, but there is no conclusive evidence about aliens, and I think that the universe is vast and boundless, and there should be aliens

First of all, our universe is very vast. Even if it's the place we humans are currently detecting. There are also more than 100 supernebulae.

There are about 1,000 galaxies like the Milky Way in one supernebula. There are about 10,000 solar system-like galaxies in one Milky Way. It is possible that there is more than one planet in a solar system that has life.

So. Let's do the math.

100 1000 10000 1 = 1 billion. In just the places where we humans have explored, there are a billion planets like Earth that can be inhabited by life. For a variety of reasons, some planets cannot survive.

If you choose one in a hundred, there are also 10 million planets that can always allow life to survive.

I believe that extraterrestrial life exists, after all, the universe is boundless, and since the earth can have life, why can't other planets produce a high degree of civilization!

It is understood that there are 200 billion "brothers and sisters" of the sun in the Milky Way, and scientists have found 150 stars with planets orbiting them, which are distant relatives of the Earth. Even if one of the 10 stars has planets orbiting, then the earth should have 20 billion brothers and sisters in the galaxy, just like only the earth has advanced intelligent life among the nine planets of the sun, then there should be 100,000-150,000 planets suitable for the development of life, and then intelligent life will be produced to form a technological civilization, and they should have a civilization similar to or more advanced than the earth.

So, the possibility of life in outer space is very high. It's just that we don't have a way to understand each other, and we learn from them and think about the same problem. Life in outer space may be more advanced than our science, it may be even more backward, and whether we can find them is unknown.

That's my opinion.

This is still an unknown question, at least for now, but with the development of space science and technology, we will find the answer, that is for sure.

Is there really any other life beyond Earth?

Aliens must exist The universe is so big that we earthlings are definitely not alone Maybe there are many galaxies similar to the solar system in the Milky Way alone! Not to mention, there are countless Earth-like planets in the Milky Way alone Not to mention the size of the universe, there are countless Milky Way, which we call extragalactic galaxies There must be galaxies similar to the solar system in the extragalactic galaxy How can you say that there are no aliens Not to mention that our solar system is still very young

Why do you still say that aliens have higher technology than us? That's because they evolved earlier than us, maybe the technology is thousands of years earlier than us, maybe higher You might say that we humans haven't discovered extraterrestrial life so far That's because the level of human technology hasn't reached a certain level It will definitely be discovered, and even interstellar tourism Einstein's general relativity theorem: The form of the laws of physics is constant in all frames of reference The content is as follows:

Albert Einstein proposed the "equivalence principle", which states that gravitational and inertial forces are equivalent. This principle is based on the equivalence of gravitational mass with inertial mass. According to the principle of equivalence, Einstein generalized the principle of special relativity to the principle of general relativity, that is, the form of the laws of physics is invariant in all frames of reference.

The equation of motion of the object is the geodesic equation in that frame of reference. The geodesic equation has nothing to do with the intrinsic properties of the object itself, but only depends on the local geometric properties of space-time. Gravity is the manifestation of the geometric properties of space-time.

The existence of material mass will cause the bending of space-time, in which the object still moves along the shortest distance (i.e., along the geodesic line - in Euclidean space, it is a linear motion), such as the earth's geodesic motion in the curved space-time caused by the sun, which is actually revolving around the sun, causing a gravitational effect. Just as on a curved surface of the earth, if it moves in a straight line, it actually walks around the great circle of the earth's surface.

In other words, there is a shortcut at both ends of the galaxy, called a wormhole, which is what we call a time tunnel, and in the end, I don't dare to say that aliens have been to Earth, but I am sure that aliens will one day be seen.
