How long will it take for humans to achieve interstellar travel in the future?

At present, it is very difficult for people to realize interstellar tourism. This is due to the limitations of technological level, so it has not yet been achieved. The technological level of interstellar tourism will not be achieved in the next hundred years. It can indeed achieve the purpose of interstellar tourism, so we can speculate from the following aspects. 1. For us, interstellar travel does need to overcome the upper limit of speed, and it is precisely because of this that it is difficult to achieve it with the current level of technology.

In fact, what I have to say is that if people want to realize economic tourism, they must overcome the upper limit of speed. For us, the speed of light is a speed that is difficult to approach. It is precisely because of this that people It is difficult for the technological level of China to meet the speed requirements of interstellar tourism in the short term. Therefore, it is precisely because of this that it is difficult to achieve the goal of interstellar tourism at present or even within 100 years. 2. It is not difficult for us to realize interstellar travel. If we can build a super-light aircraft, it can also be achieved.

In fact, it has to be said that the biggest reason for star tourism itself is the constraint of aircraft speed. It is precisely because of this that it is difficult to achieve in the short term, but in the long term, if If the aircraft can break through the speed online and reach the level of super-light speed, then it can also achieve the purpose of star tourism. 3. For us, it may take as little as four to five hundred years or as many as a thousand years for humans to realize the goal of interstellar travel.

In fact, we will find that the current scientific development has tended to stagnate. It is precisely because of this that it is difficult to make a qualitative breakthrough in our science without earth-shattering discoveries, so it is also true that This is because in the bottleneck period, it is difficult for science to make major discoveries and breakthroughs in the long term. Therefore, it is conservatively estimated that it will take four to five hundred years as long as 1,000 years to achieve the goal of interstellar tourism.

In fact, we have to say that in the future, humans will indeed be able to achieve interstellar travel, and they will definitely break through the upper limit of speed. For us, the current technological level is indeed limited, so it is difficult to achieve interstellar travel.
