Is there a precise definition of consciousness in science? Li Yu said no, consciousness so far, it is only an incomplete and vague concept, which is different from the concepts of spirit, reason, truth, etc.

For humans, consciousness is the indirect and generalized subjective reflection of the human brain on objective things. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 By extension, if a certain existence can also be aware of external objective things, then it is also right to define this existence as conscious?

But philosophically, consciousness is defined as a spiritual entity as opposed to matter, as a kind of being, so consciousness is a stream of life.

Consciousness is intelligent life? No, the definition of intelligent life, Li Yu believes that we must first recognize ourselves, that is to say, with self-awareness, we can be called intelligent life.

Then, if we regard the universe as a whole and react to objective things, we cannot say that the universe is conscious, but if we say that the universe reacts subjectively, we can say that the universe is conscious.

But how vast is the universe, and how can we know whether the reaction is subjective or passive? So there is no answer to this question at this stage.

This is the end of the discussion of consciousness, and everyone turns their attention to the point of time and space.

"Li Yu, do you have a clue for the study of time and space?" Sun Yixuan really couldn't understand the data, so she had to ask Li Yu.

"Well, in fact, you don't have to study like us, you can study the space-time point from the direction of the mage, and you won't feel confused." Li Yu first pointed out the problem of Sun Yixuan's research direction.

"To study the spatio-temporal point, we must first ignore the phenomena on the surface of the spatio-temporal point and directly observe its inner essence. The point of space-time is actually an invisible existence, which has no substance. ”

"The light we see now, the spikes are nothing more than the reaction of the space around the point of time and space to it."

Sun Yixuan was confused, what Li Yu said made sense, but there was no actual content. In the end, Sun Yixuan decided to study the time and space points from the direction of the mage as Li Yu said, maybe what else could be studied.

Li Yu did not give Sun Yixuan the substantive content because he did not have a definite conclusion. And if Sun Yixuan studies from the mage's side, maybe there will be some unexpected discoveries.

Although the space-time point was discovered by Li Yu by the means of a mage, Li Yu still subconsciously chose to study the space-time point by scientific means. However, Li Yu also thought in his heart that if he used the means of a mage to study the time and space points, the progress would be greater.

The existence of time and space makes Li Yu's thoughts seem to open a door. In the four-dimensional space, what kind of existence is the three-dimensional space? Li Yu believes that three-dimensional space in four-dimensional space is like a well-taken photograph.

The three-dimensional space in reality is like the previous film-style films, and when the photos are projected, they become what we usually see.

Time travel is to travel before these photographs. Moving from one photo to another can be challenging. This is also the reason why Li Yu thought that time travel was impossible.

Li Yu observes the direction of the space-time point, which is to observe how the space-time point connects two different photos.

Time passed quietly, and Li Yu's research also made a breakthrough. Li Yu has not yet figured out how space-time points are formed, but the research on the influence range of space-time points has results.

The range of the space-time point is 30 million kilometers from the central point of Einstar, which is almost a hundred light-years away. Time within this range is bent into a closed space-time region, that is, it can pass through the space-time point and can freely travel to and from both ends of the space-time point.

Out of this range, it is still a normal cosmic space-time. The perturbation range of space-time points reaches 50,000 light-years, and in the perturbation range, space-time is normal, but when space-time points are used, space-time in the perturbation range will fluctuate, resulting in the contraction or expansion of space-time, that is, sometimes time becomes faster and space is shorter, and sometimes time is slow and space becomes longer.

According to the results of Li Yu's research, a conclusion is drawn that the closed area where the space-time point is located is invisible to the outside world, that is to say, the closed area disappears from the normal space-time, and the closed area will not appear until the space-time point disappears.

That is to say, if there is a space-time point in a place, except for the inside of the space-time point, the outside world cannot be found and detected, which should also be the reason why no one has discovered the space-time point.

Space-time points do not appear in groups, and after a space-time point appears, the error correction mechanism of the universe will work, and this is how the closed area comes about. However, there are thousands of space-time points on Ainstar, and whether there are space-time points on the opposite side of these space-time points Li Yu is the object of the next study, but so many space-time points are very abnormal, and it is also the reason for the failure of the closed area.

"Li Yu, according to what you said, after the time and space point appears, it will disappear quickly, right?" Fang Qianmo was fully armed, and asked Li Yu in his spare time: "However, after so many space-time points, when will the space-time of this universe return to normal?" ”

Li Yu had already decided to go to the opposite side of the time and space point to start research, all the members of the laboratory would go over, he was also making preparations before the launch, listening to Fang Qianmo's question, he said with a sneer: "The reason why this situation happened later is due to the intelligent creatures of Ainstar!" The more they change the past, the more mistakes will accumulate in time and space, and this error is also a kind of energy, which will cause more and more points in time and space. ”

"But the universe has a self-correcting function, so they are done playing, and if they are lucky, after a period of time, the space-time point will eventually disappear, and this cosmic space-time will return to normal."

"If you're unlucky, there will be a supernova explosion here, which will completely destroy this space-time, and then restore it, which means that Einstar will disappear completely."

"Li Yu, you say that, if we're lucky, we'll meet the natives of Ainstar?" Lin Wanbai was ready, came to the vicinity of the time and space point, and after listening to Li Yu's words, he asked Li Yu in his heart.

Maggie and Sun Yixuan were also interested: "Is it really possible for star lovers to exist?" ”

"Is this possible? Maybe they're hiding behind some point in time and space, and they're still breathing. Li Yu sneered and said the answer.

So miserable? Don't they want to restore the balance of time and space, even if some people in the population die, not necessarily everyone is dying. After everyone listened to Li Yu's words, their expressions revealed such a meaning.

"Of course it's not going to get better! There are so many time and space points, which means that things have been so bad that they can't be worse, and it is very likely that Ainish will stop at that era, and that era will be destroyed. The age of the opposite point of time and space has not been destroyed, and it is possible that the Eins have become extinct. ”

Li Yu's words made everyone feel creepy, stop at that era, and that era will be destroyed? This means that the Aindins could experience a thousand civilizational extinctions, how tragic must that be? Civilization extinction, this kind of thing, it is enough to experience it once, you don't see the Harrow civilization that you met not long ago, after the destruction of civilization, how worried those survivors are, if the same situation happens again, it is guaranteed that they will not survive.

The situation of the Einstein shows that the Einstein people have experienced extinction disasters not only once, but eight times out of ten, as if they were idle!

Stopping the movements in their hands, Lin Wanbai and the others looked at Li Yu: "Will we save the Aiyin people who may survive?" ”

"Can't be saved! There are too many mistakes accumulated in them, and in Buddhist terms, there are too many causes and effects to be saved! ”

"In other words, at most, you can only save Ain?"

"It's still possible."
