Chapter 466

World line? Light cone?

After so many years as a high-level mage, for the first time, Gloria Augustine felt that he could not keep up with the progress. Although Lena's statement combined with the moving light point demonstration has been very intuitive, it is still difficult for Augustine to accept a new concept so quickly.

"In short, sir, if we can clearly know a particle's current position and its trajectory, then we can naturally deduce the position it will be in at any time in the past, now and in the future. This position is connected by a line, which is the particle's world line. The world line points from the past to the future, and the specific direction is the future Coordinates are presented in real space. "

When he saw that people were still confused, he drew a three-dimensional rectangular coordinate system. A point started from the origin and moved in one direction, showing a clear track.

"For the convenience of understanding, we can not discuss the situation of real space, assuming that there is a two-dimensional world with only plane."

With a wave of lenner's hand, the three-dimensional rectangular coordinate system immediately becomes the plane rectangular coordinate system. A point moves in the plane and draws a curve.

"If we change the original vertical axis Z to time, the track of this point will show three-dimensional characteristics, and this will also appear in the three-dimensional coordinate system, but the axis of time is not what we see."

"You mean high dimensional space?"

Mr. Braggs said in a low voice as he looked at Lena's presentation.

"It's easy to understand, Mr. Braggs. In fact, I prefer to call it Ian gray space, because it's not just a space with one more dimension than length, width and height, but a space-time composed of time and space."

Lena smiles. Then, he makes relevant calculation and argument, and deduces in detail the representation of Ian gray space and the world line in Ian gray space.

"It's quite another paper, Lena."

After listening to Lena's derivation, President Demetri nodded slightly.

"Ian Gray's space is not an independent theory, but a knowledge closely combined with the theory of relativity. I thought you only solved the problem of the speed of light, but you overturned the whole concept of time and space since ancient times."

Whether time is not absolute, or the speed of light is insurmountable, whether it is Reiner's theory of relativity, or this strange but harmonious Ian gray space, these things are contrary to people's past experience, intuition and common sense, but have a mathematical basis.

After this meeting, the high-level mages here realized the importance of mathematics in the study of magic. With the deepening of people's research, magic will no longer be limited to the things that people can see and touch, whether it is the changes of macro nebulae or the gathering and scattering of micro atoms, which are extremely difficult to observe directly by general means Not to mention some extreme cases that can not be achieved by current means or even in the future, it is impossible to carry out experiments at all. Abstract thinking and mathematical logic will gradually become the mainstream of mages' research.

Perhaps this is just the realization of what Reiner said before. Mathematicians are responsible for discovering formulas, while mages are responsible for finding meaning for them.

"Now it seems that the three laws of motion of Alberton are more like the macroscopic approximation of motion at low speed described in the theory of relativity. At least in the operation of stars and the vast majority of things we can touch, the three laws still apply."

Mr. Alberton sighed. His feelings were complicated. He didn't know whether it was because his whole life's hard work was proved not to be true or whether he was lamenting that the current magic system based on this didn't need to experience a devastating earthquake.

But this sentence from his mouth, it is quite desolate and helpless.

Ludwig Stein was silent, but there was a storm in his heart.

In the two clouds hanging over the head of the magic world, the problem of blackbody radiation finally led people to recognize light again from the micro perspective, while the problem of ethereal drift led the mages to redefine time and space from the macro perspective. These two seemingly different problems in the field actually pointed to the same thing at last.

Coupled with the nuclear structure model, the huge star movement is associated with the small atomic movement, which makes people daydream.

"We are in the worst of times. The cognition of the past millennium has disintegrated. Experience and common sense have been broken. If we don't pay attention, we will be left behind by the rapid development of magic."

The stars and the moon are shining on the robe, whispered the Lord lumia Calvados.

"But we are also in the best era, where the micro secrets can be explored, the macro truth can be traced, and the accumulation of thousands of years guides us to the end of exploration."

Her words are also the voice of many people here. The mages are very upset because any discovery may overturn the past cognition and destroy the academic tower that has been built for many years. At the same time, the mages are extremely looking forward to it. Because of the dissipation of the two dark clouds, people have taken a significant step in the micro and macro fields, and the mages are unprecedented Close to the truth in search, hope is close at hand."Only, Lena."

Mr. bragus said. He looked at Lena. His wise sea blue eyes reflected the handsome face of the young mage.

"The content of relativity has too much impact on the medium level mages, which is different from the dispute between the wave theory of light and the particle theory. After all, the war can not be separated from the category of wave and particle. The concept of time and space, the scale effect and the time expansion effect in relativity, if not foreshadowed by the medium level mages and some high-level mages, will probably lead to the war It will cause a huge cognitive impact, cause a wide range of cognitive collapse phenomenon, and lead to a real academic earthquake. "

What he said is exactly what Reiner considered. The subversion of the concept of time and space by relativity is not simply a further step, but a complete break and recombination. It is extremely dangerous for the middle-level mages who do not have a thorough understanding and do not study deeply in this field.

"Therefore, although the high-level Council recognizes the correctness of the theory of relativity, my suggestion is that this theory and this paper will only circulate among the high-level mages for the time being, and will not be published in any open academic journals. What do you think when our theory is gradually improved and opened to you step by step?"

Your opinion is very reasonable and no one disagrees.

Lena doesn't care about these reputations. He has only one idea in his mind, which is to improve the third equation as soon as possible.

Mass energy equation.
