In the theory of the three-body world, the universe has changed from a ten-dimensional world in the pastoral era to a beautiful era with infinite speed of light, because it has become what it is today because of the continuous reduction of dimensionality and the reduction of the speed of light, and it is also accelerating the decline of the universe.

The real world in which Jiangnan is located is actually a three-dimensional space and a four-dimensional time.

That is, high-dimensional space and high-dimensional space-time are two different concepts. For example, there is only one dimension of time in three-dimensional space, the fourth dimension of four-dimensional space still has the same properties as the dimension of three-dimensional space, and time is still a pseudo-dimension. Therefore, space-time and space should not be confused. To put it simply, time in dimensions is not time as we usually understand it. Therefore, in the three-body world, the four-dimensional space that the group of astronauts strayed into is the real four-dimensional space, and everything in the three dimensions seems so crowded. This means that, at the level of space, it can rise to a total of ten dimensions.

So now let's count space-time, the four-dimensional in the category of space-time is to add time on the basis of three-dimensional, we can understand ourselves as a point, time as a line, you follow the time line from small to large, from birth to death, you can only move forward in order, can not stop and retreat, this is the four dimensions.

If you take the time point, it is the four-dimensional space, that is, the world we live in. But you find that no, no matter how you toss, you can only live in the present. Following the law of the first three dimensions, we define the four-dimensional present us as one point, then the four-dimensional future us is another different point, if the two points are connected, it will form a five-dimensional space, in this space we can return to the past and the future at will, we are more like a bug in the five-dimensional space-time, and each section of the worm corresponds to us at a moment.

Five-dimensional space-time: It refers to the tendency of infinite unfolding at any point on the time axis in four-dimensional space. Therefore, the time line extended from any point on the time axis in the four-dimensional space constitutes what we call five-dimensional space-time.

Six-dimensional space-time is a parallel space (let's talk about parallel space non-parallel universe first), and six-dimensional is a time plane formed by making any timeline at any point in time in five dimensions intersect by changing gravity or gravity to distort the five dimensions, so that they can directly travel to another possibility, without having to go back to the point in time when the decision is changed and re-walk the timeline. In the category of five-dimensional space-time, if human beings want to change their fate, they must return to a specific point in time, and when you really change this time, there will be another timeline, that is, a parallel space parallel to our original result.

The seven-dimensional space-time is to regard the entire six-dimensional space as a point, that is, to join the singularity, that is, the point at which time begins, and the line composed of countless such points is the seven-dimensional, so that a time body is formed. Since the five-dimensional space is the worm body of time, and your fate is predestined, assuming that your final destiny is to become a doctor, we will intersect with another five-dimensional space where we take your destiny to become a lawyer, and it will be ascended to a six-dimensional space. In the six-dimensional space, you can decide your own destiny at will, whether you are a lawyer or a doctor.

According to the law of the first three dimensions, the five-dimensional synthesis of a non-six-dimensional plane will be upgraded to a seven-dimensional space, that is, a seven-dimensional body, in this space you will not decide your own destiny like the six-dimensional space, the seven-dimensional space is a collection of all your possibilities, you are both a lawyer and a doctor and a rogue. Then it also means that in the seven-dimensional space-time, the world is so beautiful, so beautiful that there will be no regrets, and even all possibilities from the most beautiful to the ugliest are concentrated in ourselves, because we can make infinite choices at the same time at any time node.

The eight-dimensional space-time is that any universe will be produced at any point on the seven-dimensional line, or similar to us, or completely different from us, the same as the five-dimensional, the possibilities of these countless universes are not intersecting, if you want to cross, you need to return to any point on the seven-dimensional line and then choose another possible universe to retake the timeline, the real world universe where Jiangnan is located, the universe of the three-body world, and the DC universe where Diana is located, in a sense, all belong to the parallel universe in the eight-dimensional space-time, No matter how you choose to go back in time in a parallel universe, it is impossible for you to travel to another parallel universe.

And nine-dimensional space-time. Similar to the six-dimensional, it is to distort the eight-dimensional by changing gravity or gravity to make the cosmic timelines of different possibilities intersect, so as to achieve the ability to directly travel through parallel universes.

The 10-dimensional space-time is that we imagine all the 3-dimensional space in all possible universes at all times as a point in the 10-dimensional space. This point already encompasses everything. Can you still imagine another point of "all the 3 degrees of space in all possible universes at all times", so this ten-dimensional space-time is a collection of all parallel universes, including all the universes that we can imagine, in fact, they are all real, and we must be able to find the corresponding universe in the ten-dimensional space-time.

Jiang Nan and Diana came back from the vast cosmic tide at the same time, looking at the empty spaceship, the two who learned the mysteries of the universe, had an indescribable feeling in their hearts.

It stands to reason that the plane light brain should be the top existence in all parallel universes, and the plane light brain that has not yet recovered all its abilities can easily shuttle between parallel universes, and Jiang Nan has the knowledge that has been precipitated by the development of a civilization for hundreds of thousands of years, which also makes Jiang Nan's ability to understand and analyze problems rise to a terrifying level, after obtaining this information at this moment, Jiang Nan vaguely feels that in fact, above the ten-dimensional universe, there may be a supreme existence that dominates all this, Each of our parallel universes seems to be a box, and perhaps the eleventh dimensional world is actually based on the ten-dimensional space with memory and perception. Albert Einstein believed that our memories can be extended infinitely, and that perception is a product of space, time, and memory. In the eleventh dimensional world, we think of memory as an objective substance that can extend infinitely.

But this box may never be able to break through
