What is the scientific basis for whether human beings will be trapped on Earth forever?

Human beings will not be trapped on Earth forever, because our scientists are constantly exploring the universe, to discover planets suitable for human habitation in the universe, and to find another galaxy that can replace the earth.

Humans are not trapped on Earth forever. Because with the development of human science and technology, it is already possible to create rockets that go to space. Therefore, human beings can also escape from the earth and explore the universe.

With the development of science and technology, human beings' understanding and exploration of the universe continue to progress, and one day human beings will leave the earth and find a new place to live.

I don't think it's possible, modern technology is advancing, we've gone from our feet all the way to airplanes, and now we're in space, and there's something else we can't do as humans.

At present, the mining of our earth has fallen to its peakThe planet is now in jeopardy. The world's oil and gas will be supplied for another 50 years, and coal will be supplied for another 100 years; For China, if it does not import from abroad, the time for oil and gas is shortened by almost 1 5, and coal is slightly more. Fossil fuels are very polluting to the environment, which is also a criticism of fossil fuels; There is very little pigment left for fossils now.

At the moment we haven't gone out of the department, not even to the moonThe main reason for this is that because of the energy problem, human beings have not yet had effective energy for space travel. At present, chemical rockets are used in aerospace, and chemical rockets have always been the mainstream products of the aerospace industry, with the advantage of simple technology and easy to obtain, and the disadvantage of low efficiency and excessive rocket volume. For the foreseeable future, fusion technology will only be used to provide energy for space activities.

Artificial nuclear fusion is a very promising technology, and once the technology of controlled nuclear fusion is mature, then we can use it, for example, to generate electricity, to use it as the power of spacecraft, all of thisIt should be widespread within 200 years.

Now that we are currently researching nuclear fusion, we can still get out of the solar systemThe Americans have developed a plan for an expedition to Mars, intending to send several astronauts to the surface of Mars by rocket. Due to the long distance, which takes about a year and a half to reach, it is no longer enough to use traditional chemical rockets, so it is necessary to develop rockets for artificial nuclear fusion. The main difficulty in this technology lies in the miniaturization of the volume, and American scientists have made some progress.

It is expected that by 2025 at the earliest, a truly reliable artificial nuclear fusion rocket will be built.

We must make this fusion research clear, or we won't even be able to get out of the moon, let alone anything else.

Because it is very difficult for humans to leave the earth to go to other planets, because there is gravity and it is not so easy to go to space.

Maybe it's because there are no more planets inhabited by humans, and the resources on Earth are limited.

Because there is no planet that is as habitable as the Earth has yet been discovered.

Because apart from the Earth, there is currently no planet suitable for human habitation.

Because the place where we have always lived is the earth, and we have never been anywhere else.

It may be that humans have never been able to set foot on other planets.

Because the money, time, and manpower required to transform a planet cannot be done by any one country alone.

I don't think it's possible that technology is advancing now. Now that we can go to space, we humans can do a lot of things.

That's because human beings have not yet developed a vehicle that can officially enter the universe.

I can't say that, because the earth is the most suitable place for us to live.

Humanity or forever trapped on Earth? Scientists: Astronauts have altered brain structure and function.
