Time travel? Humans cannot go back to the past because paradoxes will occur

Einstein was an outstanding biologist, he put forward many unfathomable basic theories, such as quantum theory, photon quantum hypothesis, photoelectric effect, etc. He also has many achievements in the nuclear industry, naturally, most famously or quantum theory. Until now, it has still become a classic basic theoretical theory. Many people feel that Einstein's brain development level is the greatest, so he can come up with this outstanding basic theory.

With the continuing trend of technological progress, many of Einstein's assumptions have been confirmed. In the case of 2016, scientists confirmed the gravitational waves proposed by Einstein. At that time, after Einstein proposed gravitational waves, he was disturbed by technical limitations and failed to verify the existence of gravitational waves from beginning to end. After that, Einstein passed away, so gravitational waves became an unsolved mystery.

However, when scientific and technological progress made new breakthroughs, scientists tried to verify Einstein's theory. It was undeniable that, after various efforts, gravitational waves were finally discovered. In addition, Einstein also put forward another hypothesis to the masses, that is, time travel.

There are time and space shuttles in many science fiction films and fantasy novels, and they all rely on wormholes to travel. Einstein thought that wormholes are a kind of media based on the middle of two times. Everyone only needs to find wormholes to travel through time and space.

From one time to another, you can get rid of the limitation of distance and go to long stars. Scientists have discovered many stars that are suitable for settlement in the universe, but the distances are too long, and the closest ones are tens of billions of light-years. If you can really find the wormhole that Einstein speculated, then everyone will be. It can reach hundreds of light-years away in a short period of time.

But unfortunately, until now, scientists have not looked for wormholes to put it bluntly, maybe wormholes are out of reach. But scientists still or want to try to find it, after all, time and space travel is very helpful for people to get rid of the earth. You can also travel back to the past to see family members you have never seen, or go to the future to see your future life.

But there are also biologists who think that time and space travel is contrary to the standard of cosmic space. It seems to be a very useful special tool that can fulfill everyone's wishes. And if we have the technicality of time travel, then we can fill in the mistakes we have made.

But in fact, this advantage can also be turned into a defect. Since we know that what was wrong in the past can be corrected by people in the future, the current people usually do not strive for perfection, and they are not careful in everything they do. The development trend of the entire history of human development is extremely bad.

There is also one point, if the time and space shuttle does exist, then it may also be used by other "alien life", and if everyone's high-tech is not as developed as the other party, then the history of human development is likely to perish. . Secondly, if everyone uses time and space indiscriminately, it will cause time confusion. Time is like a tunnel construction, if countless people enter the tunnel construction. Some want to go forward, and some want to go backward, different directions will lead to crowding, and each result will endanger the development trend behind.

Therefore, in my opinion: "It's better to travel through time and space or not have to complete it. After all, with the high and new technology in the history of human development, this kind of technology cannot be very well manipulated."
