How terrifying is the advanced civilization that has survived in the universe for a billion years?

Earth is a very powerful planet, not in terms of its size, but in terms of its life. For billions of years, countless creatures have been bred, from dinosaurs to microorganisms invisible to the naked eye, and have experienced several mass extinction events, but they are still so vibrant.

But the earth is not omnipotent, it has limited resources, and like all living things, it will have an end of life, so finding the next human home is one of the purposes of human development.

While searching for an alternative home, humans are actually looking for extraterrestrial civilizations. In the eyes of many people, alien civilizations must exist, after all, the universe is such a large environment, and there are so many planets on it, it is impossible for only a celestial body like the earth to have the ability to give birth to life. Moreover, finding an alien civilization may be of great help to human beings to achieve interstellar migration, after all, human beings are indeed limited.

But the question arises again, if alien civilizations exist, they can survive so long longer than humans, so how high is their civilization level? But knowing that human modern science and technology have only been developed for nearly a hundred years, they have reached such a level, and extraterrestrial civilizations may have 1 billion years longer than human beings, and their situation can be said to be unimaginable to us at all.

Any celestial body in the universe has the end of life, and the extraterrestrial civilization that has existed for more than 10 billion years must have encountered events such as the death of stars or celestial bodies.

It may be that they have all been able to naturally perceive which planets are going to be destroyed, and then skillfully migrate collectively to the target planets that have been found in advance. Even they are able to walk in the cosmic environment at will, and they can make full use of the resources in the universe. But why didn't they discover the Earth?

Humanity has already sent a signal in the universe, right?

Everyone is puzzled about this question. Maybe it's because the Earth is nothing in their eyes, and there are too many planets in the universe to count more than the Earth, so they don't have time to pay attention to us. Or maybe they haven't discovered the Earth yet, because it's so far away from them.

But then again, no one knows if an alien civilization is a good thing or a bad thing in the discovery of Earth. If they can find the Earth, then they must be more capable than humans. The law of the jungle is common on Earth, so will they rule over humanity?

If it did, humanity would definitely find a way to resist, and then it would be a disaster.

However, they may have a friendly attitude towards humanity, not only will they not attack humanity, but they will also help humanity achieve the great event of interstellar migration. But in any case, these are just assumptions, and based on reality, we will probably only know when that time comes.

First of all, their technology must be very powerful, so powerful that we can't resist it, and we are not sure if they have aggressive intentions and will destroy the environment in which we grew up.

I don't think it's going to be terrible, because they're going to perish after so long, so don't worry about it.

In front of their civilization, there is not much difference between our earth civilization and ants, and they can easily destroy our earth civilization.

It's scary. Because the advanced civilization that has survived in the universe for a billion years may have developed to the third universe civilization, it is very terrifying.

The universe is very ancient, with a history of more than 10 billion years of closed silver wheels, and at the same time, after an accelerated expansion process, the current observable universe diameter has reached 93 billion light years. The solar system is a primitive nebula that was born 5 billion years ago, the earth formed about 4.6 billion years ago, and life on earth first appeared more than 3 billion years ago according to current scientific discoveries.

In our subconscious, we always believe that there must be other advanced civilizations in the universe besides human beings. These civilizations are technologically advanced than humans and can do many things that humans would never dare to think of. Some civilizations may have existed for about as long as the birth of the universe, and they have unparalleled science and technology, perhaps they have reached the essence of the universe.

As far as we know, the Earth is the only planet in the universe where life exists, and intelligent life exists. However, we humans have always believed that there must be extraterrestrial civilizations in the vast universe, and that they are probably much more advanced than the technology that we humans have at this stage. We generally think that they may have developed hundreds of thousands to millions of years earlier than humans, and that a billion years is a bit too long, but it is not impossible.

An advanced civilization can be embodied in several aspects, first of all, it is very developed in science and technology, and the development of science and technology can be reflected in the manufacturing of tools, for a simple example: ultra-fast mobile devices, infinitely close to the speed of light, if you want to have such a speed, the traditional way of energy supply is naturally not realized. Secondly, in terms of physical functions, biological civilizations that have evolved for more than 1 billion years must be very suitable for the natural environment in which they live, and the development of science and technology is likely to change the way of survival.

The history of mankind is about two million years, and the real explosion of science is only a matter of the last few centuries, and the level of human beings is about the same level, which means that we have not yet fully become the masters of the earth. Then for the advanced civilization that has existed for 1 billion years, they should have reached the level of the third civilization, which means that they can travel freely between major galaxies, etc., and I can't say more, just like our Internet life today, it was impossible for humans to reach it centuries ago.

The 1 billion years of super civilization that we can imagine can be summed up in an idiom, that is, destroying the world, in our inertial thinking, to measure whether a civilization is strong or not, it is usually measured by "destructive power", the greater the destructive power, the more advanced the civilization. 1 billion years of super civilization, first of all, it is extremely lucky, because a civilization has developed from a young age to 1 billion years later, there are too many changes, take human beings as an example, if human civilization has developed for more than 1 billion years, at least it can travel the universe!
