, the " two-way foil " weapon of higher civilization is suffocating. The dimensionality reduction strike it produces turns the entire galaxy into a "paint".
"Dimensional Reduction Strike"
People can't help but think, what is the dimension space? What is four-dimensional space? Can we, who live in three-dimensional space, get there?
What is four-dimensional
Four-dimensional space is an mathematical concept . Mathematicians regard three-dimensional space as three-dimensional space composed of x-axis, y-axis, and z-axis. Adding a time axis to the three basic axes is four-dimensional space .
This is the simplest and basic concept. Mathematicians also define four-dimensional space through the changes of low-dimensional space . For example, one-dimensional space is a straight line, and countless straight lines add up to form a plane, that is, two-dimensional space.
0~5-dimensional space
Countless planes superimposed becomes a three-dimensional space, where there are both width and thickness in the space, and people live in such a three-dimensional space.
and so on. Countless superimposed in three-dimensional spaces is the basis for forming four-dimensional space. This superimposed state may be much more complex than humans want.
For example, the superposition of space state can be accurate to to . On the human timeline, the superposition of countless second spaces has completely exceeded human imagination.
With logical thinking, it is impossible to infer the existence of four-dimensional space. No one can explain clearly what the four-dimensional space is. It can only abstractly express a concept of .
4D space concept
Just like the existence of two-dimensional space, it cannot understand the human beings living in three-dimensional space, and the creatures living in two-dimensional space, it cannot understand the so-called three-dimensional.
Because in their world and thinking, there is only length and width , it is difficult for them to recognize the existence of height. Even if they realize that their world lives in two dimensions, they cannot form a three-dimensional structure in their thinking.
What is so simple to humans may be something that can never reach for two-dimensional creatures.
Similarly, when humans understand four-dimensional space , they become the same as two-dimensional organisms understand three-dimensional space.
Four-dimensional space features
First of all, the characteristic of four-dimensional space is the reversibility of time , because in four-dimensional space, all time is superimposed. If humans live in four-dimensional space, they can trace back to any point on this timeline through a timeline.
Four-dimensional space imagination
Simplely put, this human living in four-dimensional space can return to any time in the past at will.
However, this timeline has been fixed by to . Although it can go back, it cannot change the development trajectory of time. What kind of state is going back to the past and whether there will be paradoxes, humans have no way to know.
followed by infinite size . In 1858, mathematician Mobius discovered that after twisting a strip of paper 180° and then pasting both ends together, it looked very magical.
Ordinary paper strips have two sides, and the pasted paper strips become one side . When ant is placed on it, you don’t have to cross the edge of it when climbing the complete sheet of paper strips.
Ants will never crawl to the end
Some problems that cannot be solved on plane were actually solved on the Mobius belt.
Some people speculate that this mobius ring is likely to help humans understand four-dimensional space.
It turns out that Klein was inspired by it. In 1882, the famous Klein bottle was created. The Klein bottle is regarded as an object connecting to four-dimensional space.
There is a hole at the bottom of of the bottle, and the bottleneck is connected to the hole at the bottom. This bottle has no edges or internal and external differences, which means that the bottle can hold the water of the entire universe.
However, it is difficult for Klein bottle to show its specificity in three-dimensional space. Only when it is placed in four-dimensional space can it show its original appearance.
Klein bottle CG
Klein bottle in three-dimensional space can only be an Concept . The glass model created by scientists represents a guess about four-dimensional space.
Interestingly, by cutting the Klein bottle vertically from the middle , you can get two Mobius rings, which connects the theories in the mathematical world.
In short, four-dimensional space is very wonderful. All objects in it transcend human cognition. Only when humans change their way of thinking can they better understand four-dimensional space.
Is it possible for humans to reach the fourth dimension?
The answer is , which is negative by . Take three-dimensional and two-dimensional as examples. If human dimensionality reduction strikes are placed in two-dimensional, all organs of the human body will not be able to operate normally.
2D space concept
On a plane without thickness , humans seem to be unable to even count the specimen.
Therefore, if humans want to reach four-dimensional space, they must change the existing form of to adapt to the infinite superposition state in the four-dimensional space.
What will humans become? It is hard to say to clear them. They may become an "spiritual body" . No matter how superposition of four-dimensional space is superposition, it cannot affect human activities.
, and the mental body cannot interfere with the timeline of the four-dimensional space, which conforms to the essential characteristics of the four-dimensional space.
Some people speculate that human spiritual thinking is likely to be in four-dimensional space-time or even higher dimensions. For example, when humans dream, they can shuttle through the time axis at any time, and even between different time axis.
Time and Space Shuttle Concept
Specifically, when a person fails to get into the university he likes in reality, but passes in a dream one day, that is, the person's spiritual body travels to other timeline .
However, many scientists do not agree with this conjecture, because some scientists believe that human dreams are caused by cerebral cortex memory factors, and are not so fantasy.
Some people even speculate that when humans are in the process of humans, the "spiritual body" goes to the four-dimensional space, and body is the most fundamental factor that binds humans to the four-dimensional space.
The latter's guess is not unreasonable, because the body is indeed a factor that restricts humans from going to four-dimensional space, but it is impossible to know whether there is "spiritual body" after humans die.
Spiritual Body Conception
You should know that the body is the fundamental survival of humans in three-dimensional space . It is almost impossible for humans to achieve a leap in dimensions.
Maybe one day, the advanced alien civilization will come to the solar system, and will strike humans with a "four-directional foil" liter . However, whether this advanced civilization exists is unknown, and everything has become so mysterious.
Alien Conceive
Dimensional Space-time
Humans live in three-dimensional space-time. When the space dimension continues to to stretch upwards, everything becomes wonderful.
Four-dimensional space-time naturally needs no mention. When space reached five-dimensional , timeline appeared branch , and the flow of time is no longer one-way, but consists of countless branches.
5D space model
When a person makes a choice, it is possible to generate many branch lines . Organisms in five-dimensional space-time can shuttle between each time and time line, and they can freely control the time .
In the movie " Interstellar ", when the protagonist falls into "black hole" and enters a wonderful world, this is the high-dimensional space-time conceived in the author's mind.
Black hole
In this kind of time and space, all the time is like a book displayed on the bookshelf, and is clearly visible.
Six-dimensional space-time means that distorts all time lines of five-dimensional space-time, so that all time points intersect. In simple terms, you can directly distort any time point to get the desired time line.
Six-dimensional space concept
and without going through the timeline, you can directly get to the desired result in .
7-dimensional space can treat six-dimensional space as a point. The line composed of countless points in six-dimensional space is seven-dimensional space. The creatures in it can directly get the results they want without making any changes.
start point is infinite possibilities and end point is infinite possibilities, but only the result you want in will appear. After
reaches the eighth dimension, the timeline will extend to each universe . Each universe is a singular point connected into a timeline. This timeline has experienced the entire time from the birth to the end of the universe.
9-dimensional space-time, The timelines of each universe intersect and can start at any node in the universe.
9-dimensional space concept
000 dimensions, including in the first nine dimensions all possibilities .
eleven dimensions, ten-dimensional space is composed of memory and perception .
All dimensions above three-dimensionality exist in theory, and there is no scientific experiment to show whether really exists in , so just be happy.
The vast universe still has too many unknowns to humans. I believe that in the future, humans can uncover the mystery of the universe .
