The famous astronomer Ptolemy once said: Because human beings are now in a three-dimensional space, all parts of our human body will be strictly restricted by the three-dimensional order, even the brain is no exception. So in the three-dimensional world, it is difficult for us to imagine the structure of four-dimensional space and the distribution of things.
For us, the four-dimensional world is just an illusion. It is difficult for us to know what the situation is. We can only imagine its possibility infinitely, but there is a big gap between imagination and reality.
Since it is a myth, heaven obviously does not exist, but it was imagined by human beings out of awe of natural phenomena and ignorance of natural laws in the past.
Take the myth of China as an example. Heaven has not been found in modern aviation and astronomy research. That heaven exists in another space, which is one more dimension than our present three-dimensional space. In addition, there is a saying called "one day in the sky, one year underground", which shows that heaven and our time are not treated, adding a dimension.
Heaven belongs to three-dimensional space. The space where immortals live is different, and according to different levels, several-dimensional spaces are also different. It is also recorded in many books that there are 33 days in the world, which proves that there are 33 spaces. Human beings live in a three-dimensional space, and people living in each one-dimensional space are different. The higher they live, the greater their ability.
The space after death is also different, vegetable leaf network, each space contacts different people. In the TV series, you will see that some immortals will disappear and disappear directly. If you explain it scientifically, you will enter another space.
