The earth's immigrant base

Moving to another planet is a long-cherished dream of mankind. How wonderful it is to stand on a vast planet and watch the sunrise and sunset and have a good look at the earth! On this beautiful planet, people work at sunrise and rest at sunset ... However, it is not easy to move to another planet.

First, we must find a habitable planet. Some people once thought that Mars and Venus might be good choices, but scientists soon found that other planets around the sun were not suitable for human survival. Some scientists have summed up four criteria, and only when these criteria are met can galaxies be the most suitable for life. According to these standards, there are five galaxies in the universe that meet the standards.

The problem of the planet is solved, and another huge problem stands in front of us like an iron wall.

Of these five galaxies, the nearest one, if it wants to fly there, it will take tens of thousands of years to arrive at the current speed of the space shuttle. However, the United States is currently studying a "hyperspace engine." Once the "hyperspace engine" is proved to be feasible, it only takes three hours to get from Earth to Mars. However, even if we reach a planet suitable for survival, how can human beings solve a series of problems such as diet and life?

Although these ideas have not been realized, with the rapid development of science and technology, it won't be long before we can move to another planet. Therefore, we should work harder now and make contributions to the cause of science!
