Travel through the Qing Dynasty and become emperor

Chapter 1028 The Mystery of Relativity Theory

"Even if it is true, how do you know that the holy gun can be used to activate Mata Hari One?" Johnson was very puzzled.

"It has to start with the designer of Mata Hari [-]." Lewis replied, and then asked, "Guess who is the designer of Mata Hari [-]?"

"Isn't it von Karman?" Johnson asked doubtfully.

"No, it's Einstein that you would never have thought of!" Lewis said amazingly, stunned all the people present.

"Einstein? Albert Einstein?" Johnson asked in surprise, "How is that possible?"

"That's him," Lewis said quietly.

The high-speed elevator quickly rose to the ground, and the people in the elevator were silent for more than a minute. No one could believe that the most powerful super weapon in the United States was actually designed by Einstein, who had defected to the enemy.

Lewis continued: "Mata Hari is the greatest spy of the twentieth century, but this woman has one of the biggest characteristics, that is, she only recognizes money but not people. For money, she was employed by France, Britain, and former Tsarist Russia. , as well as China, it is said that there was an ambiguous relationship with the romantic emperor of China. After the Beijing Peace Conference, the world has returned to peace, and the role of Mata Hari will inevitably be weakened. We take advantage of the This opportunity brought this woman over with a large sum of money. Under our instructions, Mata Hari obtained a large amount of information about the development of the atomic bomb from Einstein by using the identity of a multi-material spy, and also took a volume of microfilms. Film, this roll of film becomes the basis of the design of the space-time machine, which is Einstein's manuscript of relativity. In [-], we instructed von Karman to organize forces and build the space-time machine according to Einstein's manuscript of relativity. To commemorate Mata Hari's glorious career, we named it 'Mata Hari One'."

The more Johnson listened, the more confused he became: "I have heard about the relationship between Mata Hari and Einstein, but this woman is unpredictable. Are you not afraid that she will sell American intelligence to other countries?"

Lewis smiled coldly: "Yes, so after completing the development of the space-time machine, we sent someone to secretly execute this woman."

Johnson took a breath, "However, there is still a question. Before Einstein left the United States, he had been secretly monitored by the FBI. After he left, he did not take a piece of research results with him. Why did he send people to steal it? ?”

Lewis replied: "Most of the materials Einstein stayed in the United States stayed at the level of physical theory and even philosophy. His research theories after he came to China were more practical, and his theories were continuous, and only part of them were obtained. There is no way to start, and the only way to follow is to connect his theories before and after. Of course, Einstein's most creative theories were put forward in China, and those stolen by Mata Hari are only a small part of them. From this we can see how terrible Einstein is. But Mr. von Karman can turn a bunch of boring words into real results. From this point of view, he is as great as Einstein."

By this time, the four had returned to the Oval Office of the President.

After the four sat down, Lewis went on to say: "The birth of the space-time machine is mainly based on the two hypothetical theories in Einstein's special theory of relativity and the mysterious theory of thinking space."

"Oh, tell me, what's going on here?"

Lewis chose a comfortable sitting position, like a teacher giving a lecture to elementary school students, "The velocity synthesis method in classical mechanics actually relies on the following two assumptions: 1. The time interval between the occurrence of two events and the state of motion of the clock used to measure time No relationship; 2. The spatial distance between two points has nothing to do with the motion state of the ruler used to measure the distance. But Einstein found that if the principle of constant speed of light is compatible with the principle of relativity, then these two assumptions must be abandoned .At this time, events that occur simultaneously to one clock may not necessarily be simultaneous to another clock, and simultaneity becomes relative. In two coordinate systems with relative motion, measure the distance between two specific points The obtained values ​​are no longer equal. The distance is also relativity. Einstein derived the relationship of time progress between different inertial systems, and found that the time progress of the moving inertial system is slow, which is the slow clock effect. It can be understood as, motion A clock runs slower than a clock at rest, and the faster the speed of movement, the slower the clock goes, and when it approaches the speed of light, the clock almost stops. The length of the ruler is the two endpoints obtained 'simultaneously' in an inertial system The difference in the coordinate values ​​of .

Due to the relativity of 'simultaneity', the lengths measured in different inertial frames are also different.Einstein proved that the moving ruler in the length direction of the ruler is shorter than the stationary ruler, which is the shrinkage effect. When the speed is close to the speed of light, the ruler shrinks to a point.From the above statement, we can see that the principle of clock slowness and ruler shrinkage is that the progress of time is relative.That is to say, the time progress is related to the frame of reference.This fundamentally negates Newton's absolute space-time concept. Einstein believes that absolute time does not exist, but time is still an objective quantity.For example, in the ideal experiment of twins, the elder brother is 15 years old after returning from the spaceship, and the younger brother may be 45 years old, which means that the time is relative, but the elder brother has indeed lived for 15 years, and the younger brother has indeed believed that he has lived for 45 years. Regardless of the frame of reference, time is 'absolute'.This shows that no matter how the object is in motion, the time it experiences is an objective quantity and is absolute, which is called the inherent time.That is to say, no matter what form of exercise you take, you think you drink coffee at a normal rate, and your life patterns have not been disrupted, but others may see that you drink coffee for 100 years, and from putting down the cup to It took only a second to die. "

Johnson half-understood, and asked again: "So what is a four-dimensional space?"

Lewis explained: "One-dimensional is a line, two-dimensional is a surface, three-dimensional is a static space, and four-dimensional is a dynamic space, because of time, of course, this is just a way of saying, not to say that the fourth dimension is time. In physics The changing parameters necessary to describe a changing event. This parameter is called dimension. Several parameters are several dimensions. For example, only the angle is needed to describe the position of the "door", so it is one-dimensional instead of two-dimensional. To put it simply: the zero dimension is a point, without length, width, or height. One dimension is a line composed of countless points, which only has length, without width and height. Two dimensions are a surface composed of countless lines, with length, width, and height. Width has no height. Three-dimensional is a body composed of countless faces, with length, width and height. Dimension can be understood as direction. Because human eyes can only see three-dimensional, it is difficult to explain more than four-dimensional. Just as a person with normal intelligence is born without a People with only one eye and one ear, so there is no binocular effect, binaural effect, it is difficult for him to understand distance, he probably thinks that the world is 2-dimensional. For example, a water pipe, people generally think it is A three-dimensional object, but when viewed from a distance, there is only one line left, which is 1-dimensional.”

Seeing that the president seemed to understand, he went on to say: "Einstein believed that the four-dimensional space-time is the lowest dimension that constitutes the real world. Our world happens to be four-dimensional. As for the high-dimensional real space, at least we can't perceive it now. We To give an example, if a ruler rotates in three-dimensional space (excluding time), its length remains the same, but when it is rotated, its coordinates change, and the coordinates are related. Four-dimensional space-time The meaning is that time is the fourth-dimensional coordinate, and it is related to space coordinates, that is to say, space-time is a unified and indivisible whole, and they are in a relationship of 'one ebbs and another'."

"Einstein once made a classic hypothesis on the feasibility of human beings traveling through high-dimensional space. First, he assumed that a piece of paper without thickness (only having length and width) represented a two-dimensional space, that is, a plane; The pen draws a circle and a point on it, and assumes that the circle and the point can move on the plane (paper). Of course, the point cannot penetrate the circle, and the circle has physical constraints on the point at this time. However, if the When several or even dozens of sheets of paper are stacked together, the original paper and the later paper form a three-dimensional space (with length, width, and height at the same time); in this way, circles and points that were originally in two dimensions have The ability to move in three-dimensional space, that is: front, back, left, right, up, down. Obviously, the constraints of circles to points are also lost. From this metaphor, we can see that some interactions between some objects during the journey from two dimensions to three dimensions Maybe it will disappear; and by analogy to humans, this will have disastrous consequences. Just imagine that if blood vessels lose their restraint on red blood cells, humans will die of excessive blood loss in an instant during the journey in the first four-dimensional space, so theoretically speaking , travel to the fourth dimension and beyond is not feasible."

Johnson was confused, "Since this is the case, wouldn't the space machine be meaningless then?"

Lewis smiled mysteriously, "Science is very strange. Many things that were known to be unfeasible have been broken by people. The reason why I say von Karman is great is because he broke Einstein's hypothesis and made human beings travel through time and space. It’s no longer a luxury.”

"How did he break that assumption?"

"It's up to him to ask himself. This is the key to the space-time machine. I don't think that stubborn guy will tell this secret."

At this time, Hoover said: "But according to the secret information collected by the FBI, it should be possible to travel through time and space. Let me give you a few examples." Hoover took out a black notebook from his leather bag, opened it and read: " Event 1916: In [-], a strange incident also happened in the mysterious waters of Bermuda. In front of many onlookers, the American fighter plane was swallowed by the cloud and disappeared.”
