As India's plan, what are the difficulties for human beings to live in space for a long time?

According to relevant media reports in India, India is currently planning to be able to survive in space one day in the future, and has also formulated relevant routes and frameworks for this goal. In the future, the whole country will make efforts to fulfill the lifelong wish of mankind. Although this kind of imagination is very good, and each of us has imagined that if one day in the future, the resources of the earth have been exhausted, then how should human beings survive? Are we really going to emigrate to space like the movie said?

However, although the vision is beautiful, there are still many difficulties in this plan at present. For example, is there an environment suitable for human survival in space? Are there inexhaustible resources for human use like the earth? At the same time, whether our advanced modern technology can be moved into space, whether we can support human survival in space through effective scientific means, and so on.

There is another earth in the world. In fact, from an academic point of view, since we live on the earth, the entire outer space galaxy must exist on the same planet, just like life on the earth that we don't know about. Maybe we are aliens in their eyes. Just limited by the current technology, there is no way for human beings to explore whether such a space really exists in this space physics. For this proposition, human beings are constantly studying, including film and television, and there are also many materials to instill in human beings that there are indeed aliens in this world. It can also be seen that human beings have been making progress in this imagination.

One day in the future, we will rush out of the earth. Although people pay more and more attention to environmental protection and the concept of one earth, we have to say that maybe one day in the future, we will really rush out of the earth. Especially in the face of irresistible natural disasters, can we realize the vision of escaping from the earth through space flight? At present, as far as the history of human exploration is concerned, no other planets suitable for human survival have been found. Even if we go to Mars, not only are we not as rich in resources as the earth, but even the air environment is not conducive to the survival of the earth.

Although we ancient people began to explore the hope of flying into outer space one day, we can't realize this dream because of the current scientific principles. In particular, Newton's gravity tells people that even if an object is thrown into the sky, it will fall at a speed invisible to the naked eye. But in any case, it is good for human beings to have this vision. We don't rule out that a spacecraft system suitable for human beings may be built at some time in the future, and more and more people will be led to explore the mysterious universe and outer space.
