If humans want to travel to the stars, how long do you think it will take?

Such a problem must be considered after reaching the speed of light. So I believe that this cannot be solved in a few hundred years.

In 3000, humans have almost figured out how to use wormholes. By then, a distance of one light-year can be traversed in less than an hour or two. Wouldn’t it be possible to travel through space and interstellar travel? Humanity still needs to develop interstellar tourism for at least another thousand years. . . Ten thousand years is also possible. . . The development of modern science and technology is of a leap-forward type. Maybe if a certain technology takes a big step forward, we will be able to travel among the stars.

There is no way to predict. Maybe human beings will not survive until then. When nuclear fusion technology achieves a breakthrough, navigation within the solar system can still be predicted. Interstellar travel is too far-fetched and may not be possible in another five thousand years. . I think it is possible, but first it is a theoretical breakthrough. In recent decades (almost a hundred years), there have been no truly epoch-making breakthroughs in theoretical physics, but applied physics is developing rapidly. Theoretical physics is currently showing signs of fatigue in supporting the development of science and technology, and is in urgent need of updated theories. This will encourage countries to invest more energy in theoretical physics research. I think there may be breakthrough achievements in physics in the past few decades; on a large scale and thousands of years of history, as long as humans still exist, theoretical physics can develop several times, interstellar Traveling is definitely possible.

Interstellar travel is a sign of Level 2 civilization. Being able to travel interstellar proves that we have solved the energy problem, or that we have learned to use the energy of stars. We are now roughly at 0.6 to 0.7. If you do the math, it has only been more than 3 million years since the birth of human beings. It will take only one or two thousand years for human beings to reach the first level of civilization. By the time of the second level civilization, human beings will either have migrated to other planets or they will be finished long ago. According to the current efforts of human beings to cause harm to the earth, human beings will not be able to survive until that time. However, if an opportunity similar to the industrial technological revolution arises, it will accelerate the progress of human civilization. It’s not impossible. Humanity’s current scientific and technological civilization is only a matter of the past one or two hundred years. Scientists predict that a new technological revolution is coming soon, and perhaps artificial intelligence is one of them.
