Conditions for interstellar flight

The universe is boundless, and the interstellar darkness is boundless. One day, we will explore the unknown new world, the red flag will fill the universe and civilization will light the stars.

Distance is the most practical first problem in interstellar flight. Proxima centauri is the closest star to the solar system, 4.22 light years away, and there is a planet in the habitable zone. If it can be accelerated to one tenth of the speed of light, it will take 42.2 years for the spacecraft to fly. With the development of biotechnology, the average life expectancy of human beings will increase, which is an acceptable journey. Using gravity slingshots, solar sails and their own propellers, we can accelerate to the best fifth of the speed of light with almost no resistance between stars.

Communication is to overcome the second problem. The existing communication speed on the earth will lag behind on the cosmic scale, and superluminal communication is an indispensable technology to explore other galaxies. At present, quantum communication without considering distance communication is extremely important in the future. The distant starry sky will be in the same time and space because it is synchronized with the earth's time.

Developing a new planet from scratch requires automatic production. Passengers in interstellar flight must be a few people who explore the unknown world. Many planetary environments in the new livable zone need to be transformed to be suitable for survival. In order to follow the arrival of immigrants, pioneers need to establish a continuous production base on a new planet. Automation and intelligent robots are the best choices with limited manpower.

Frog-leaping fission exploration will be an efficient exploration method. The solar system is the starting point and base. Pioneers confirm the route and new environment, followers build bases, immigrants develop new planets, and finally take this as the starting point for the next round of exploration.

The future is infinitely magnificent and the starry sky is infinitely beautiful. In the future, you will chat with friends under the stars.
