Is it possible that there is an interstellar war going on somewhere in the galaxy now?

Personally, I think this topic is exactly the same as whether there are aliens in the universe, because only the existence of intelligent creatures can make interstellar war possible, otherwise this topic is false, and everyone says it is not. Therefore, if there is evidence that there are one or several other civilized planets or extraterrestrial intelligent beings in the Milky Way, there is still a great possibility of interstellar war in the Milky Way.

So is there an intelligent and civilized "alien" in our galaxy?

According to our existing cosmological knowledge, such as the famous Fermi paradox, there are about 250 billion stars in our galaxy, and there are countless planets around them. Even if there is a small probability of intelligent life, there should be a considerable number of civilizations around these stars. There is also the famous "Drake formula", which also calculates that there are a considerable number of civilizations in our galaxy, so I won't go into details here. Because even if they talk too much, none of the examples are convincing.

In order to confirm whether there are "aliens" in the galaxy, human beings have also used various scientific and technological means to find them. Regrettably, no strong evidence has been found to prove the existence of "aliens" in our galaxy. Therefore, according to the existing knowledge of cosmology, we can "assert" that there are no "aliens" in our galaxy, or at least we can think that there are no highly developed intelligent and civilized planets. Because a civilization that can launch an interstellar war should at least have the ability to sail on a large scale, as long as there is a large-scale conflict, according to the existing scientific and technological level of mankind, it can still detect a little information. For example, China's "Eye of the Sky" has this ability. It can search for cosmic signals of 65.438+0.37 billion light years, not to mention that the diameter of the Milky Way is only 65.438+million light years, and it is possible to capture "aliens" at this distance.

To sum up, according to the current detection level of human beings, we have not found a highly developed intelligent life planet in the Milky Way. From the existing cosmology, the possibility of a large-scale interstellar conflict in the Milky Way is very small. But this possibility is not without, if there is, it should be billions of years before or after the emergence of human civilization! The emergence of cosmic civilization may also have a sequence, and our generation of human civilization may have missed it ...!

Thank you for reading! ! !

Then I don't know, I can't see that far, and the gods can't do anything about it.

However, fighting in the galaxy should be impossible. Did anyone fight in a galaxy that was too close? For example, proxima centauri, the closest galaxy to the solar system, is still a three-body galaxy, with a distance of more than 4 light years. If there is fighting here, we can see it in four years. Unless the aliens here are bacteria and spit on each other, we can't see how to fight. However, it should be unreliable to spit on each other and develop into Star Wars.

Most likely a galaxy. It is estimated that the Milky Way is suspended, and there are two livable planets in this galaxy. Later, when the civilization here developed to be similar to ours, we could emigrate and then emigrate to the planet to fight the home planet. Isn't that how American independence works? It's just that this is an interstellar war. Well, no one stipulates that planets are not interstellar.

In this case, we will see the use of some high-energy weapons. Such as gamma rays released by a huge nuclear explosion.

In reality, we can observe many gamma rays from unknown sources, and these energy sources release huge energy, which may be the collision of neutron stars or black holes, or the fight between immortals, hehe. Gamma ray bursts may have destroyed most livable planets. After the fight, it will take us tens of thousands of years to see what is thousands of light years away.

However, there is still no direct evidence that there are other civilizations besides us. I can only guess.

A: According to the latest data released by NASA, there are nearly 200 billion stars in the Milky Way, and almost every star has planets around it. So probabilistically, there should be many advanced civilizations in the Milky Way, so interstellar war is also possible.

The history of the Milky Way is over 654.38+0 billion years. Our solar system is about 4.6 billion years old, and life on earth has been around for about 3 billion years. The earliest ancestors of mankind can be traced back to 3 million years ago. From the perspective of time span, the time of human existence is only a moment relative to the age of the Milky Way.

At present, the farthest distance that a human aircraft has flown is 0.003 light years (Voyager I), the radius of the solar system is about one light year, and the diameter of the Milky Way is as high as 200,000 light years. From the scale point of view, the range of human contact is only a drop in the ocean compared with the Milky Way.

Then it is entirely possible that somewhere in the galaxy, there is a more advanced civilization, and even interstellar travel can be realized. If there is a more advanced civilization, then conflict is also possible.

However, with the current observation technology of human beings, it is still impossible to directly detect distant interstellar wars. It is difficult for humans to detect the planets in the star system closest to the solar system. The strongest electromagnetic wave emitted by human beings will be completely submerged in the cosmic noise when it travels to 100 light years away.

According to the classification of cosmic civilization, human beings are currently at the level of 0.7 and cannot make full use of the resources of their planet; To achieve interstellar travel, you need at least two civilizations, just like the three-body civilization in the novel Three-body.

At present, human beings have not discovered alien civilization, which may also be a good thing for the earth, because alien civilization may not have a good impression, and human science and technology has only appeared for more than 200 years. If advanced alien civilization exists, then in terms of probability, the developed degree of alien civilization is definitely much higher than that of earth civilization. Maybe human beings will become "mice" of alien civilization.
