When converted into probabilities, how likely do you think aliens exist?

Converted into probabilities, there is a probability that aliens exist is about 60% to 70%.

The universe is so big that we can't imagine it, and to this day, we haven't found aliens, but that doesn't mean that aliens don't exist. Maybe aliens discovered humans, but humans didn't perceive it. Maybe human beings only exist in the form of animals in the eyes of aliens, and for aliens, we exist in the eyes of aliens in the way of aliens, which is really unimaginable when you think about it.

The astronaut looks at the vast universe in the spaceship, boundless, and looks back like the earth, like a speck of dust. Human beings have never stopped exploring the universe, and the moment they step out of the earth, it means that human beings have taken a big step forward in the exploration of the universe.

Human civilization is a member of the civilization of the universe and the civilization of the solar system. When we know the insignificance of human beings and the earth, the question arises, is there a possibility of aliens in the vastness of the solar system? I believe that everyone who is curious about the universe and the sun will have such a question.

The answer is very certain, in the solar system, there is a possibility of aliens, not to mention the wider universe. But the aliens have not been discovered by me, because the universe is too big, the solar system is too big, and the level of human exploration technology needs to be improved. In addition to the solar system, there are galaxies such as the Milky Way, extragalactic galaxies, etc.

In the process of human exploration of the solar system, Mars is one of them, and it is also one of the few members. Only knowing the terrain, there is no answer to whether there is life or not. If the universe is a desert, then humanity is just a grain of sand.

We have found no traces of extraterrestrials, but that doesn't mean that aliens don't exist. The connection between the earth and the universe and the solar system is not the only criterion for judging things. <>

Most of the people's understanding of the universe comes from science fiction ** and movies, so the probability of the existence of aliens is still more likely.

If converted into probabilities, the probability of the existence of aliens is less than 1%, and if aliens really existed, they would have been discovered by humans long ago.

Probabilistically speaking, it's 100% existent, but we haven't found it. At present, the scope of space that human beings can explore is only a drop in the ocean, and there must be aliens in other places.

I think there is a 50 percent probability that there are aliens, because for me there are only two possibilities: aliens and no aliens, so in terms of probability, these two possibilities account for 50 percent each.

1 in 100 million probability. Even if there are aliens in the universe, humans will not be able to discover them, and aliens do not need human existence.

The exploration of the universe has always been pursued by people and scientists, and many scientists actually support the claim that there are aliens in the universe, and there are also many evidences or opinionsAt the same time, some people will ask what is the probability of aliens in the universe? I think the probability is relatively large, and it can even be said that the probability is more than 50%, which is just a guarantee, after all, the universe is too grand.

3. The probability of the existence of aliens in the universe is completely inclined to the scientific and technological level of human beings and the progress of human cognition, and it has to be said that there are alien planets, but aliens will be found over time. In fact, for us, the probability of the existence of an outer line in the universe is often close to 0, but it is constantly shifting with the progress of human beings and the exploration of human beings, and the progress of science and technology in the world.

In fact, for us, the probability of the existence of the appearance is not close to 0, but in the end, the progress of our human science and technology, the way human beings perceive the universe is also constantly changing, so the probability of detecting aliens is also constantly improving, because of this, the probability of human beings discovering aliens will only get higher and higher.

It's big and it's small. It's big because the universe is so big, so there's a big chance of life there's going on. It is very small because the conditions for the existence of life are very harsh, and people have not found any other planet to meet these requirements except for the Earth.

Personally, I think it is 100%, because the earth is also a planet in the universe, it has given birth to tens of thousands of life forms, and there must be life on other planets, but whether it is the same as human beings is uncertain.

It should be 100%, the universe is huge, humans can see very little, there must be other planets suitable for survival, and extraterrestrial life must also exist.

It should be very high, because there may be many Earth-like planets in the universe.

The probability of aliens not being very high, but I think aliens should exist, but we can't find them yet, or never will. Do you think, how can there be only earthlings in the vast universe and countless planets? According to the research of American scientists, our galaxy alone is estimated to have 20 billion planets like the Earth (previously said that there are 2 billion, 60 billion, etc., in short, the number is very amazing), these planets have the conditions to support the existence of life, which means that not far from the earth, there may be extraterrestrial life.

And billions of extragalactic galaxies as huge as our own have been discovered in the universe! Therefore, it is safe to say that there are countless planets in the universe that are suitable for life and aliens!

According to the latest reports, the latest research by Australian scientists says that there may be 200 billion terrestrial planets in the Milky Way, and there may be life on these planets.

Although it is generally believed that there will be extraterrestrials in the universe, modern astronomical observations have ruled out the possibility of extraterrestrials in the solar system. Entering interstellar space in light years is a distant distance that is difficult for us humans or other intelligent beings to conquer! Therefore, the huge distance in space seems to be an insurmountable obstacle to the interconnection of intelligent beings, so even if there are aliens, it is difficult for us to find out, and we do not know that they live in**.

So we don't know anything about the living conditions of aliens, let alone whether their technology is more advanced than ours. You can imagine that even the speed of light of 300,000 kilometers per second would have to travel for years, decades, hundreds, tens of millions of years, or even longer! What an unimaginably long and long distance!

Therefore, it is simply impossible for the so-called aliens to visit or invade the earth, or even kidnap and control the earthlings! Constrained by the laws of physics, it is hard for me to believe that intelligent beings can build spacecraft that can fly at the speed of light, which is all science fantasy, how can it be so easy? Therefore, it is not credible.

Taking a step back, even if intelligent beings were capable of building superspacecraft that could travel at or beyond the speed of light, it would be impossible to move freely in the vast interstellar space measured in light years. I am pessimistic about this, and I believe that human beings may only be able to exist alone forever in the universe!

It can be said that so far there is no real and credible evidence that aliens have visited our earth, and all rumors about aliens visiting earth are not credible. Therefore, I can tell you with certainty that no one has ever seen aliens with their own eyes, and that there is no scientific basis for what aliens look like.

What do real aliens look like? Is it so ugly? It may always be a mystery for us.

I believe that many friends have had similar questions in their childhood or adolescence, the universe is so big, is there only intelligent life on the earth?

The universe is so big, is it possible that only the earth has intelligent life?

When I saw the problem, my first reaction was:

Drake's formula.

It is a judgment that there may exist within the Milky Way.

A formula for the number of extraterrestrial civilizations with advanced means of communication.

Drake's formula.

The number of extraterrestrial civilizations with advanced means of communication.

Formula n is the number of extraterrestrial civilizations.

r* is the rate at which stars are formed within the Milky Way.

FP is the proportion of stars that accompany planets.

NE is the number of terrestrial planets within each star system.

FL is the proportion of planets that have evolved to inhabit them.

FI is the probability of evolving a highly intelligent life.

FC is the probability that this civilization has technology and we can communicate.

l is the life span of the existence of advanced technology.

As we can see, these seven are all variables, and it is very difficult to actually get accurate data. But from the estimates.

At the minimum, let's.

Inside the Milky Way. There is an advanced civilization.

The number is 40.

The maximum is 50 million. That is, according to this formula, the probability of an advanced alien civilization in the Milky Way is 100%.

The lowest value within the Milky Way.

The number is 40.

Don't get excited, though, as the chances of being able to communicate with each other are very small. Because after considering the size of the Milky Way, it is found that the core of the Milky Way in our solar system is 10,000 light-years. In other words, even if this extraterrestrial civilization is 5,000 light-years away from us, the signal will come and go for 10,000 years.

。But.. 10,000 years. What a long time!

Even if this extraterrestrial civilization is 5,000 light-years away, the signal will come and go for 10,000 years.
