In another 10 billion years, can man dominate the universe? The reality is very cruel

Five billion years ago, the center of a fast-moving Nebula lit up on the Orion spiral arm, the third spiral arm of the galaxy. Since then, the sun was born. It is the center and core of the solar system. With the birth of the sun, the solar system has taken shape, and eight planets are emerging.

More than 4 billion years ago, the earth was very ordinary. It was no different from other planets. The surface is a bad planet with lava flowing everywhere, but the earth is very close to the sun. After hundreds of millions of years of bad environment, with the continuous cooling of the earth, a beautiful ecosystem has been formed.

With a beautiful ecosystem, primitive life on earth was born in the ocean 3.8 billion years ago. After billions of years of evolution, intelligent life human was finally born hundreds of years ago. After continuous evolution, human beings formed primitive civilization 5000 years ago, went through various stages of civilization, and embarked on the road of scientific and Technological Development hundreds of years ago.

Science and technology give human beings wings of flying, let us go out of the earth and see the vast universe. Only when we really walk out of the earth, we all know how small the earth is and how small human beings are. At that time, the dream of human beings changed from dominating the earth to dominating the universe. We imagined that one day, human steps could travel all over the universe, conquer countless cosmic civilizations and dominate the universe.

In the view of many people, although human science and technology are still very backward, and human civilization is not even a first-class civilization, human science and technology is developing very fast. As long as we can continue to develop, we believe that one day we can dominate the universe. And some people also put forward a limit time, that is 10 billion years, at most after 10 billion years, human beings can dominate the universe.

So can human beings really realize this wish in 10 billion years? 10 billion years is undoubtedly a very long time. It is only 13.8 billion years since the birth of the universe. Perhaps in people’s eyes, science is omnipotent. The end of science development is theology, and God is superior to the universe and can dominate the universe.

Theoretically speaking, as long as we give enough time for the development of science and technology, we can conquer and dominate the universe. Ideal is beautiful, but reality is often very cruel. Now let’s briefly analyze whether human beings have the hope to dominate the universe in 10 billion years.

According to current cosmology, the universe was born in the singularity explosion 13.8 billion years ago, and then gradually evolved into a colorful universe through the continuous expansion of the universe. No one can give an answer to how big the universe is now, because the speed of galaxies away from us will accelerate with the increase of distance. When we reach a certain distance, the speed of galaxies away from us will exceed the speed of light. At that time, photons will not be able to come to the earth, and we will not be able to observe the Galactic space there.

Therefore, scientists put forward the concept of observable universe range. At present, the observable universe range of human beings is about 93 billion light-years, and this range may only be the tip of the iceberg of the whole universe. The real universe range is too large for us to imagine.

With such a vast observable universe, how can we achieve free exploration and reach every corner? If you want to reach a distant place, speed is the key. Without the advantage of speed, everything is empty talk. The reason why people in ancient times could not understand the earth was that they could not reach the other end of the earth without advanced means of transportation.

After human beings enter the era of science and technology, we have fast transportation tools such as airplanes. At this time, the distance of the earth is becoming shorter and shorter, and we can reach every corner of the earth’s surface in a very short time. Technology has turned the earth into a global village. On the earth, the speed of sound and supersonic is a speed that we think is very fast.

But this speed is not even tortoise speed in the universe. To explore the universe, we need faster speed. However, Einstein’s theory of relativity tells us that the speed of an object cannot be increased infinitely. It has a limit, that is, the speed of light. The speed of a mass object can only be infinitely close to the speed of light.

The speed of light is an extreme speed in our cognition. Can we explore the universe freely at such a speed? The answer is No. You should know that the diameter of a small galaxy is 100000 light-years. If the spacecraft shuttles in a straight line at the speed of light, it will take 100000 years to get out of the galaxy. On top of the Milky way, there are larger superclusters, hundreds of millions of light-years in diameter.

It is obviously impossible to walk out of this supercluster at the speed of light. In fact, even if human beings can fly at the speed of light in the future, the areas we can explore are limited to the very limited starry sky around the solar system, not even the free exploration of the galaxy, let alone the whole universe.

Of course, relativity does not make people despair completely. It also puts forward the concept of space-time distortion. Under the space-time distortion, the phenomenon of superluminal velocity exists. The expansion of the universe beyond the speed of light is a kind of space-time distortion. The larger the mass, the greater the degree of distortion.

The mass of black hole is undoubtedly the largest among the celestial bodies recognized by human beings, so the space around it is very distorted, and the gravity generated by this distortion makes light unable to escape. The theory of relativity has also led scientists to guess the curvature engine, which is that the spaceship uses space-time distortion to compress the space in front of the spaceship and expand the space behind the spaceship.

In the curvature engine mode, the spaceship will be wrapped by the space-time bubble generated by the distortion of space-time, and then move forward rapidly with the flow of space-time. This kind of sailing speed is faster than the speed of light, it does not violate the theory of relativity, the speed of the spacecraft itself is static, and the real movement is the bubble of time and space surrounding it.

So can the curvature engine take us to every corner of the universe? The answer is No. At present, the curvature engine is only a theoretical conjecture, and it is very likely to be realized in the future. However, according to the research of scientists, even the highest level 9.9 curvature engine, the speed of the spacecraft is only ten thousand times the speed of light.

This speed is incredible when we see it. It’s only minutes to get out of the galaxy. It allows us to explore a large number of galaxies around the galaxy. However, if we want to explore the observable range of 93 billion light-years at this speed, there is nothing we can do. The curvature engine can’t even realize the free exploration of the observable universe, let alone the vast universe.

Curvature engine can’t make human conquer the universe, so what speed mode can we use? The last thing left is the wormhole that’s still being guessed. Wormhole is also a conjecture under Einstein’s theory of relativity. It is the product of the extreme distortion of space-time, connecting the two spaces of the universe.

No matter how far away the wormhole is, we can reach it in a short time. Even at the edge of the universe, as long as the wormhole is connected, we can go to explore in a short time regardless of the distance. However, whether this kind of wormhole beyond our imagination exists is still a mystery. Scientists have not found any suspected wormhole in the universe.

https://recordunknown.com/wp-content/uploads/2021/03/c8033d55-ac26-4bba-b166-5c1c7f02b206_5.jpegAlt

Some scientists speculate that the massive black hole in the center of the galaxy may be a wormhole, but the nearest massive black hole is 25000 light-years away from us. If we want to explore it, only human beings can achieve the curvature engine navigation, and how many years will it take to achieve this goal.

And whether human civilization can last for 10 billion years is still unknown. According to the current understanding of scientists, in the earth’s 3.8 billion years of life, no living creature or civilization can continue. What’s more, there is no doubt that there is an alien civilization in the universe. The main reason why we can’t find it is that the distance scale of the universe is too exaggerated, and human beings haven’t been able to go out of the solar system to explore.

If there are a large number of alien civilizations in the universe, at the age of 13.8 billion, the early cosmic civilization may have been born more than 10 billion years ago. If these cosmic civilizations can continue to develop until now, science and technology will reach a height we can’t imagine.

If so, these advanced civilizations should have the strength to travel all corners of the universe and become the overlord of the universe. But why is the universe so lonely that there is no trace of any advanced civilization visiting the earth? There are two possibilities for this situation. One is that the early cosmic civilization has ended and disappeared. The other is that the early cosmic civilization has no ability to travel all over the universe.

If it is the second case, it shows that it is basically impossible to develop into the hegemony of the universe in 10 billion years. From the perspective of the universe, human beings are just ordinary intellectual civilization. What can human civilization do that other cosmic civilizations can’t do?
