Why do some people say that humans can never leave the galaxy?

The thickness of the Milky Way is 3000 light-years, and human beings have not yet crossed the distance of 1 light-day, so from the current level of human science and technology, human beings really cannot get out of the Milky Way, but technology is constantly developing, and it is not impossible to get out of the Milky Way.

The farthest flying vehicle of human beings is Voyager 1, which has flown 22 billion kilometers, and it takes more than ten or twenty hours for the signal to be transmitted back, but it is still less than the distance of a day's flight (about 26 billion kilometers), although Voyager 1 is a few decades ago, but until now there is no subversive breakthrough in human space technology, and it is still driven by chemical energy, which cannot make the spacecraft obtain one thousandth of the speed of light, and the speed is at most several times to more than ten times that of Voyager 1.

And the solar system, the Milky Way is nothing else, it is big, it is calculated in light years, if you can't break through the existing propulsion method, flying out of the solar system is a luxury, it will take tens of thousands of years to get out of the solar system, flying out of the galaxy is something you don't have to think about, it's almost delusional.

Pessimistic view of the development of human science and technology, you will get the view that human beings will never be able to leave the galaxy, but the advantage of human beings is that they have never stopped exploring, with the continuous increase in the exploration of the universe, they will be able to understand more cosmic phenomena, and they will be able to continuously improve their scientific and technological strength, and maybe they will be able to find a way out of the galaxy.

There are many pioneering ideas in Germany during World War II, but at that time, due to the lack of materials and energy, it was not enough to support the idea to become a reality, but now many ideas at that time have become a reality; 10 years ago, we were still using the straight board machine of the turtle, a few years, now every year there are many new mobile phone products, and the quality of communication and other functions are also developing rapidly, it is not an exaggeration to describe it with each passing day.

In theory, there are special cosmic phenomena such as impulses, which can communicate two star fields, greatly shorten the distance of flight, and if you can find a wormhole, you can fly out of the galaxy in a much shorter time, but it also requires a greater development of human beings' own scientific and technological strength, at least to abandon the existing chemical energy, such as using controllable nuclear fusion as energy, using the curvature engine as a propeller, and controllable nuclear fusion has now seen some light, and China has achieved 50 million 100 seconds of operation, It is possible that in the coming decades, humanity will have access to the infinite and clean energy generated by controlled nuclear fusion.

Looking at the problem from the perspective of development, flying out of the solar system and even the Milky Way is only a matter of time, but this time span may be very large, at least we can't see the feat of human aircraft flying out of the Milky Way, flying out of the solar system is a slight possibility, Hawking platform proposed "breakthrough star plan" wants to build a laser matrix, create a miniature spacecraft, use the laser matrix to accelerate the probe to about 20% of the speed of light, you can achieve a centaur three-star system that reaches 4 light years away in a few decades.

Because the technological level of human beings is still relatively low, and the galaxy is very large, some people say that human beings will never be able to leave the galaxy.

Because the speed of the spaceship is impossible to fly out, it is very far away, and the galaxy is a terrible place for humans to fathom.

The main contradiction determines the nature of things, and human beings are constrained by objective laws, such as science and technology, the human body itself, and so on, which become the decisive factor that can never leave the galaxy.

I think the most important reason is that the Earth is a circle, and the Milky Way is the result of orbiting the Earth.

This problem is at least for now, it is more difficult to get out of the galaxy than to save people who have died, with the current level of science and technology of our human beings, let alone out of the galaxy, it is difficult to get out of the solar system. So we really can't get out? Not necessarily, but it is very difficult for human civilization now, we live in a four-dimensional space-time, and the highest speed in this space-time is the speed of light, but if it can exceed the four-dimensional, then it can fly at a very high speed or even exceed the speed of light!

For humans to get out of the solar system, the speed of spacecraft must be closer to the speed of light. Humans can't stay in space for 50 years. To get out of the galaxy, the ship has to speed at the speed of light.

This is a question for the people of the future. Modern people can control nuclear fusion frustration, and it seems impossible to break out of the great yang system. If you want to get out of the galaxy, it is not completely impossible, at least human civilization needs to be upgraded several levels, have the ability to transcend space and practice, and have the ability to explore higher dimensions, just simply increase the speed, even if you master the nuclear fusion technology, it only solves the energy problem, and it is still too early to fly out of the galaxy!

At least I won't be able to see it in my life.

The concept of time is relative, for people who are fleeting and have a life span of less than 100 years, 10,000 years is already astronomical, and for the entire universe, 100 million years is a flick of a finger. At this stage, the first task of human beings is to fly out of the earth and immigrate to extraterrestrial planets, and the time is very short, once the migration is successful, the seeds of the earth's creatures are like being put in a safe, and there will be no repeat of the extinction of the dinosaurs. Then there is the possibility of flying out of the solar system and out of the Milky Way.

As long as human beings do not kill each other and do not destroy the environment of their home planet, human beings will be allowed to go out of the earth and become a member of the cosmic civilization, not to mention the Milky Way, out of the universe can be, the vastness of the universe, how can human beings be detected by existing technology, what human beings are now exploring is not even dust in the universe, nor can the distance of space in the universe be determined by the speed of light.

If you want to fly out of the Milky Way, the best way is to do it through wormholes and warp speed, but so far scientists do not know anything about wormholes and warp speed theory, so if you want to get out of the galaxy, human beings do not know how long and what month they will have to wait.

Of course this is true, because the Milky Way is very big, and we humans are very small standing in the Milky Way, like a speck of dust.

It's not true, because scientists are very intelligent now, and their IQ is also very high, so in the future, they will definitely let human beings out of the galaxy.

The Milky Way, a vast celestial system, is made up of at least 200 billion planets with an aperture of nearly 160,000 light-years. Our solar system sits on the hunter's arm of the Milky Way, about 10,000 light-years apart from the Silver Heart. In the solar system, sunlight leads the eight planets and their many stars to revolve around the core of the Milky Way at a speed of 250 kilometers per second, and it must be 100 million light-years to rotate once.

So with such a huge scope, can humanity escape the Milky Way and run towards the longer night sky?

Although Voyager 1 has flown to interstellar space 21.1 billion kilometers away from the Earth, Voyager 1 has only flown 20 light hours away from the vast indoor space of the universe, and it will have to take a dry year to fly out of the solar system. It is already known that the aperture of the solar system is about 2 light years, the aperture of the Milky Way is about 200,000 light years, and the distance between 1 light year is about one trillion kilometers.

Seeing this set of data information, it is indeed difficult to get rid of the solar system at this stage, and it is true that it is impossible to get out of the Milky Way, and now there is only a wait, until one day, human scientific research on the speed of light is successful, and suddenly the light-speed spacecraft or faster-than-light rocket is built, and the experiment is successful, and the speed of the interstellar empire vacation travel spacecraft has reached more than 500,000 kilometers per second, and the Chinese nation will celebrate at that time, and the people will be happy. I only hope that human beings can complete the great dream, and I also look forward to the solar system aperture is 2 light years, and you can also go to Jupiter on a rocket ship to see, and by the way, explore what the edge of the solar system is, whether there is a wall to protect alien creatures, but don't have any unexpected surprises.

For example, entering other planets in the Milky Way must also be based on which super-black holes are at the gates. Naturally, the technology of this spaceship, if you can make the people in the spaceship not easy to have the cycle of life and death, it will be the happiest, but even if you can't make the people in the spaceship immortal, it will also maintain the daily life of the people here until they are oldAnd it can be passed on from generation to generation in the spaceship, and life can be maintained from generation to generation, so that it can be regarded as attracting outer space, otherwise it is really human beings who can't get out of this galaxy.

It's not that there is anything in the way, but if you leave the Milky Way, then there is no way for human beings to survive normally, and according to the current astronomical and aerospace technology, scientists have no way to do it, and there are other galaxies except the Milky Way.

It is because the human ability is not enough, and there is no air in the universe, and it takes absolute speed to get out of the galaxy, in fact, it is mainly the resistance of the air to come out.

This is due to the enormity of the Milky Way, the vast extent of space, and the great distance between each planet. The reason for the presence of people is that other planets are not inhabited by human beings, and there is no environment and climatic conditions for human beings to live.

This is because the Milky Way is a very huge existence, but there are many planets in the Milky Way, and if you can't jump from Earth to another planet, then you can't get out of the Milky Way. Of course, it is the climate and temperature outside the universe that hold people back.
