Voyage of the Stars.

Chapter 644: Membrane and Spacetime
Many scholars believe that it is correct to interpret the experiment from the perspective of string theory, because they already know that a Level 4 civilization can travel at warp speed and achieve superluminal communication. So based on known information, it is speculated that tachyons are likely to be the product that must be discovered when exploring the grand unified theory.

According to the known "Grand Unified Theory", it is the symbol of a Level 4 civilization. While a Level 4 civilization masters warp speed, it will also have means of superluminal communication. So perhaps the technology of warp speed navigation and tachyon technology are both based on the discovery of the Grand Unified Theory.

Although this consideration is a bit far-fetched, it is not without reason.

In other words, humans have not yet mastered the grand unified theory, but have taken the lead in discovering the tachyon, which was supposed to be discovered after the grand unification. Although it was discovered indirectly in a coincidental way, it is still a discovery.

So is it possible to infer clues of the grand unified theory from the logic of the indirect discovery of tachyons?

Some scientists have already thought about this. After all, the grand unified theory is the goal of mankind. Only by realizing the grand unified theory can mankind truly understand what tachyons are and make it possible to create superluminal communicators, detectors, and warp engines.

So, what kind of mechanistic relationship exists between them?
Human scientists are helpless about this for the time being, because they are still stuck in the debate over whether the experiment is correct from the perspective of string theory. Some think it is correct, some think it is wrong, and some even suspect that the string theory's description of this aspect is wrong, so they come to such a conclusion that contradicts the experiment.

Their reason is that interpreting the experiment from the perspective of string theory only makes humans suspect that they have discovered tachyons, but the application of tachyon technology and even the more specific theories about tachyons have not changed. They say that even if the explanation from the perspective of string theory is correct, it is only equivalent to humans barely proving the existence of tachyons, and this proof is still questionable.

In general, there were many different opinions, and scientists were divided into several groups, each with their own views and opinions. For a long time afterwards, the academic community was very lively, with academic seminars, scientific exchanges, principle debates, and even criticism meetings specifically targeting string theory.

Many people have expressed concern about the disagreements in the academic community, but Yue Yuan is optimistic. In his opinion, compared to the past century of experiments with no progress at all, he would rather see the current situation, even if it may be caused by a false and wrong conclusion.

He himself has never expressed any favoritism towards various opinions. As a leader of civilization, he remains neutral and supports the respective views of all scientific teams.

Yue Yuan’s attitude is, to a large extent, actually the attitude of the new government.

Scientists who understand this point will not have so many concerns and will continue to debate and research. The truth will only become clearer as the debate continues, and wrong things will not stand up to scrutiny.

Of course, Yue Yuan is not sitting there with his legs crossed and watching the fire from the other side of the river. After all, mankind has long established scientific supremacy, and the new government is mainly composed of technical bureaucrats. In this case, Yue Yuan, as the leader of civilization, will also participate in meetings on the development of science and technology.

It's just that he seldom speaks, and mostly attends scientific seminars with different opinions as an observer.

For example, at this moment, Yue Yuan was sitting in a seminar on string theory, membrane, grand unified theory, tachyons, warp speed, and a series of other physical relationships. According to human technology today, meetings are usually held in the virtual world. Each participant will connect himself to the virtual world through a virtual cabin, and control the character created for him in the virtual world from a first-person perspective. However, perhaps these scientists are a little nostalgic, and this meeting is rarely held in the real world.

Yue Yuan was listening attentively in a corner of the venue.

The meeting had been going on for about an hour, and at this moment a scientist who supported string theory was passionately expressing his views on the stage.

"D-branes are familiar to us all. They are places in spacetime where strings can end. What I want to show you now is that we can imagine them in another way."

At this point, the screen in the conference hall immediately displayed the PPT video presentation prepared by the scientist, and it was synchronized to the personal terminal of each participant through the venue's auxiliary AI, including Yue Yuan.

Seeing that the data were synchronized, the scientist on the stage continued, "We can imagine them like this. They are black holes with a temperature of zero. When we have many membranes, one on top of another, I think this is a good idea because it is likely to be the answer we are looking for.

OK, let's start with D0-branes, as explained by our civilization in the last meeting, in string theory, there is no net force between two D0-branes. Their gravitational attraction is exactly offset by their electrostatic repulsion,

They will not annihilate each other like D0-branes and anti-D0-branes, so we can consider putting two D0-branes, one on top of the other, or even stacking as many as we want without worrying about violent reactions like annihilation between them. "

"Everyone knows that the mutual annihilation of D0-branes and anti-D0-branes will produce tachyons. So what if multiple or even any number of D0-branes are stacked together? Everyone must be curious about what physical phenomena will be used. Of course, when it comes to physical phenomena, we must consider the background of the physical phenomena, whether it is the background environment of the grand unified theory in our theory, or the background of the universe in the current galaxy era."

"In addition, everyone should know that at this stage we have no way to perform superposition experiments between arbitrary D0-branes. Yes, we cannot precisely manipulate D0-branes, but that does not mean we have no way to manipulate D0-branes at all."

Hearing this, everyone in the conference hall nodded. It was indeed true. If humans had no way to manipulate the D0-brane, there would be no previous theory that interpreted the experiment from the perspective of string theory. Obviously, this so-called operation was the astronomical particle collider.

The scientist who stated his point of view paused for a moment, then raised his hand and pointed to the changing animation video on the screen about the influence of D0-branes on each other, and spoke again: "The theory is that the more D0-branes are superimposed, the more the space-time around them is distorted. This may be the clue we have found about the relationship between the information about the principle of warp speed travel and the grand unified theory.

The interaction between D0-branes is likely to hide the secret of warp speed, which is also related to the change of mass. D0-branes, tachyons, space-time distortion, warp speed. When we can truly sort out their relationship and find corresponding evidence in experiments, perhaps we will truly discover the grand unified theory. "
