"Red Boy, do you already know everything about the situation in the outer plane?" Lu Xiaoqi looked at this child's innocent appearance, and was a little worried that he had failed to absorb the memories in the consciousness body of the base master's brain. Pen "Fun" Pavilion www.biquge.info

"Yes, Immortal Lord!" The red boy got the name and was happy, but when he saw Lu Xiaoqi asking, he immediately sat down on the lotus platform seriously, looking like a little adult, which made Anne and them laugh.

"But I'm going to start with the basics, because it's a bit complicated to explain, Immortal Lord Rongyu!" Red Boy said.

Everyone sat on the couch and waited for the speech of this "little adult".

"What I'm going to talk about next is the spatial dimension, note that it is not the space-time dimension, let's remove the variable 'time' from all systems for the time being!" "Because no matter what the spatial dimension, there are variables of time."

Everyone's expressions, including Lu Xiaoqi, were a little weird, because they suddenly got to the point, and they cut to the topic of physical science from the beginning, and they still spoke from the mouth of such a mysterious "creature", and the sense of disobedience was too strong.

It's like Taishang Laojun opening the altar to preach, but talking about Einstein's general theory of relativity.

"Immortal Lord, you should know that any space can be divided into countless tiny 'points', we can say that the dimension of this 'point' is 0, that is, the zero-dimensional space; if these points are connected into a line, then this line is 'one-dimensional space'; countless lines combined, whether they are juxtaposed and squeezed together, or interspersed with each other, in short, they can form a surface, then this surface is 'two-dimensional space'; The surfaces are superimposed to form a three-dimensional structure with length, width and height, and this three-dimensional structure is a 'three-dimensional space'. Red Boy said.

Lu Xiaoqi nodded, this is common sense, he knows that Red Boy said this to pave the way, after all, there are still people like Mo Ye who have no foundation in the modern knowledge system on the scene, from simple to deep!

"The next higher dimension of space cannot be vividly depicted in the minds of all three-dimensional creatures, including human beings, because it is impossible to construct a four-dimensional space by superimposing three-dimensional objects as before-no matter how three-dimensional objects are superimposed, it is still three-dimensional, but the volume has become larger! What is four-dimensional, human beings can't even imagine a model, that's because human beings themselves are only three-dimensional, the brain structure, and even the 'electrons' in the electrical signals of the cerebral cortex are three-dimensional, and the 'talent' is so, the limitations are there, it is impossible to imagine a four-dimensional object, even if the four-dimensional object is in front of you, you can't see it! Red Boy said.

"So, from the memory of the base mastermind, I got a unified standard for judging the spatial dimension of objects: projection!" "Every object, no matter what dimension it belongs to, under the same 'light source', the form when the projection area is the smallest is a dimension one level lower than it!" ”

"What do you mean? Let me give you an analogy: for example, if we think of a chopstick as a straight line, how do we swing it in the sun so that the shadow area is minimized? As I just said, the 'point' is zero-dimensional, so add one dimension to the zero-dimensional foundation, and the straight line represented by the chopsticks is a one-dimensional object! ”

"In the same way, if a piece of paper is projected on the ground at least (side to sunlight), it is a straight line, then the paper representing the 'face' is a two-dimensional object! Human beings project the smallest on the ground, even if this person is as thin as a bamboo pole, his projection cannot be 'point' or 'line', only 'surface', then we say, human beings are three-dimensional objects! ”

"Then, of course, those who are qualified to be called four-dimensional objects must be able to project a three-dimensional structure, or rather, this projection can occupy a three-dimensional space!" "In this universe, or in the universe as all three-dimensional beings know it, there is no existence that can do that, right?" ”

Lu Xiaoqi nodded, he had really never heard of this kind of standard for defining dimensions before.

"In that case, let's turn this inference in reverse: if you can make your projection three-dimensional, then you can say that this being is a four-dimensional being!" Red Boy said.

"So, are those demon clans and other invaders four-dimensional creatures?" Lu Xiaoqi asked, he remembered that the demon liked to proudly claim that he could "project" on the earth plane, and these projections all had a three-dimensional structure.

"Of course not!" A trace of disdain appeared on the red boy's face, "They are just lustful for themselves, deceiving themselves, they are just projecting their magic and part of their consciousness to other planes, just like puppets like remote robots, they are not 'four-dimensional creatures'!" ”

"So, is there a dimensional difference between the 'low plane' and the 'high plane' mentioned by the base master before?" Lu Xiaoqi asked again.

"Of course not," replied Red Child, "the number of dimensional universes is endless, more than all the insects on Earth have laid eggs in the last hundreds of millions of years!" But even so, they are just separate 'eggs', and the difference between high and low is only determined by the number of intelligent civilizations within them and the solidity of the universe itself! They're all three-dimensional! ”

"So, what's the situation with that 'plane angler'?" Lu Xiaoqi finally asked the question he was most concerned about.

"If the Demon Clan is a self-deceptive and self-contained person, using 'little tricks' to deceive himself and make himself think that he is a 'four-dimensional creature', then the 'Plane Angler' is the real 'Forward', he will look for everything possible to 'advance', and his method sounds simple: look for high-dimensional projections!" Red Boy replied.

"He also started from dimensional exploration, and the interesting thing is that before he found the three-dimensional projection of the four-dimensional object, he first found the projection of the higher dimension - the immortal lord you should know that in your universe, there are all kinds of cosmic laws, such as the laws of gravitation, such as the laws of thermodynamics, and the universe where the 'plane angler' itself is located does not have these laws, that is to say, the various physical laws that are 'iron rules' in this universe do not apply to his universe at all! After exploring many cosmic planes, he found that most of the universes have the same basic physical laws as your universe, and some universes will change their cosmic laws irregularly! And this transformation will actually 'infect' the neighboring planes! In other words, a certain universe may have a variety of chaotic and overlapping cosmic laws due to changes in the surrounding planes! ”

What does this mean? This means that those laws of the universe are also projections! Not from a four-dimensional projection, but from a higher order, which even the 'plane angler' can't understand! Can you imagine? Is gravity also a high-dimensional projection? Red Boy said.

Lu Xiaoqi's eyes widened, Xiao Ba's pupils flashed with blue light, obviously calculating and understanding, Anne frowned, and the cadre Mo Xie couldn't understand anymore.

A vast worldview that has never been seen before is displayed in front of everyone's eyes, and the infinite universe seems as small as dust. (To be continued.) )
