If people can live forever, is there anyone willing to leave the earth and travel to the stars in infinite time?

This is almost a question without suspense, and human beings can certainly achieve interstellar travel! But because of the theory of relativity, interstellar travel may actually be completely different from what we thought. The immortality of human beings means that it is possible to reach the outer space of the solar system even in a spaceship with a slow flight speed. Many people will voluntarily give up all life on the earth and embark on an interstellar journey. First of all, a big obstacle must be space technology. The celestial bodies outside the solar system are far away from us, and at present, humans can't build a spaceship fast enough.

Secondly, in order to realize interstellar travel, we need huge financial support, but no one is willing to invest. In fact, the technical obstacles actually stem from the problem of funds. As long as the investment is regardless of the cost, technological breakthroughs will naturally follow.

At present, one of the constraints on human large-scale space navigation is technology and the other is life. Technology includes many aspects, the first is the speed of the spacecraft, and the second is the fuel of the spacecraft. So far, mankind has not found a high energy density fuel for long-distance interstellar travel. With the modern human aircraft (Parker Solar Detector), it will have the fastest sailing speed in human history in the future, but it will take thousands of years to reach proxima centauri, so the life span is also an important factor limiting interstellar travel, unless human beings come up with the technology of "artificial hibernation".

Exploring the unknown is something that has been repeated in human history. After man mastered fire, he wanted to do more things with fire, so metal tools appeared; When the rocket was invented, people wanted to see the moon, and finally the United States achieved the feat of landing on the moon in 1969. A large part of human groups have a strong desire to explore, and it will be a great event that they are eager to embark on a strange star path.

Life means more possibilities, but manned deep space exploration is an endless unknown journey. Even if the spacecraft carries all the materials needed for interstellar travel, it is still a lonely journey that not everyone can bear.
