How many years will it take human beings to travel around all the planets in the universe?

It is impossible for human beings to travel all the planets in the universe.

The reason is simple: the universe is finite and unbounded, and it is impossible to realize all observations.

Even if this planet is really livable, there is almost no possibility for human beings to immigrate into space now. This star is 600 light years away from the earth, and it takes 600 years to fly at the speed of light, so it is unrealistic to immigrate. In the 40 years since the launch of the Voyager spacecraft, the earliest flight only reached 150 astronomical unit (that is, the average distance between the sun and the earth was 150). Therefore, with existing scientific and technological means, it is impossible for human beings to move in space. "

Using wormholes to realize instantaneous motion: With the development of science and technology, new research has found that the super-strong force field of wormholes can be neutralized by "negative mass" to stabilize the energy field of wormholes. Scientists believe that antimatter also has a "negative mass" relative to the "positive matter" that produces energy, and can absorb all the energy around it. Like wormholes, "negative mass" was once thought to exist only in theory. However, many laboratories in the world have successfully proved that "negative mass" can exist in the real world and captured a small amount of "negative mass" in space through spacecraft. Scientists pointed out that if the "negative mass" is transferred to the "wormhole", the "wormhole" is opened, and its structure is strengthened and stabilized, the spacecraft can pass.
