According to the current speed of scientific and technological development, when can space jump and interstellar travel be carried out?

This question is a bit of science fiction. I predict that interstellar travel should be at least at the end of this century, but if you want to travel in space, you can travel in space now, but it depends on your efforts.

If we want to achieve space jump, I'm afraid it will take N centuries, and it's still unknown whether Chengdu can achieve it by then. However, as a sci-fi fan, I still hope to achieve space jump.

As far as you are concerned, can mankind develop by leaps and bounds? My answer is no.

There are no examples of leaping development in the history of human civilization, but things like the Egyptian pyramids are still a mystery. I think this mystery should be solved around 10, but I predict that it will not be built by aliens. I suggest you watch "Ten Thousand Years of Prehistory", but you can only treat it as a science fiction film, but you can't take it seriously.

In the last 500 years, I will definitely see alien bases. First, it must be built on the moon. If the landlord can live to that time, maybe I can go to the moon and date Chang 'e! However, if you build a colony, it is an unknown number, because so far, humans have not found any alien life. You know, how can you come to the colony without alien life?
