The National Aeronautics and Space Administration (NASA) of the United States has discovered a super earth, which can reach as far as 3 1 light-year. How long will it take for space migration under the existing conditions? Recently, NASA discovered "Super Earth", which is 3 1 light-years away. If people really want to leave the earth by spaceship, go to this "super earth" to open up new land and become space immigrants, how long will it take for space travel with the existing scientific and technological conditions? First, let's change the unit of light years. A light year refers to the distance that light travels in a straight line in a cosmic vacuum for one year, which is 9460730472580800 meters. It is a unit calculated by time and the speed of light. 3 1 light-year is 2.9322644650e17 meters, which is a terrible number.

Now let's look at the maximum speed that a modern spaceship can reach. Juno, the space probe of NASA, reached the maximum speed of 265,000 km/h (73.7 km/s), which is 26,500,000 m/h, which is 2321.400,000 in adulthood.

Fuel, food, oxygen, all materials will become insurmountable obstacles for people to fly to another "earth" now, not to mention the limited life span of human beings. If you can't effectively isolate the harmful rays in the universe, it is quite dangerous to live in a spaceship for a long time or even for a lifetime. Just kidding, even if human beings can solve material problems in this 1000-year-old cosmic journey, generations of human beings who have multiplied in spaceships may have become another species by the action of various rays when they arrive at that planet.

In a word, if humans can't develop faster space flight tools or find a more convenient way to reach that planet, the dream of this space immigrant may never come true. Since we can't catch up with the second earth for the time being, please protect the earth where we live. Now, we don't have that much retreat.
