Four-dimensional space has been proved to exist. What happens when humans go in? Liu's guess is exciting.

According to scientists' cognition, the dimensional space that human beings can observe and live now belongs to two-dimensional and three-dimensional, but in fact, it is around 1950, and some scientists have certified the existence of "four-dimensional space". Liu's Three-body once expressed his views on four-dimensional space, saying that four-dimensional space has one more dimension than three-dimensional space, and this dimension is the time dimension, so in Liu's view, if human beings are in four-dimensional space, they can "control" time at will.

Although the four-dimensional space can't scientifically explain its content, according to Liu, there is no time division in the four-dimensional space, and human beings can control their life span in the four-dimensional space like cultivating immortals, thus achieving the desire of immortality. When human beings are fully adapted to the living environment of four-dimensional space, time travel is not a dream. Although Liu's description of four-dimensional space is "attractive", it is actually only speculation or fantasy.

How influential is the famous science fiction writer Liu's "Three-body"?

Three-body is a science fiction novel, but it doesn't affect people's love. At the 73rd World Science Fiction Convention, Liu won the Hugo Award, which was translated into 25 languages and sold well all over the world, attracting praise from world celebrities. For example, Obama said that the content of "Three-body" is very imaginative, and even he feels that he is really too small compared with the universe in the three-body Zuckerberg also said that he liked "Three-body" very much and recommended "Three-body" to fans.

In fact, there are many science fiction novels or movies in our life, including domestic and foreign ones. But compared with science fiction works, it is not difficult to see the uniqueness of Three-body. Science fiction shows more fantasy, but when fantasy may conform to reality, it is easy for people to have different understandings of it. This is also the reason why "Three-body" has been popular at home and abroad.

With the increase of scientists' exploration of outer space, we also have an understanding of the universe. The earth is too small in the universe, so what we usually see and hear may not be true in the universe. Perhaps the parallel world and time travel in our movies seem unfounded, but in the vast universe, it is possible to realize it. Therefore, I hope that friends who have time can go to see "Three-body", which will improve the pattern and make a leap in thought.
