[Progress:96.3]

What is space-time?

To put it simply, it is a collective noun of time plus space.

To put it a little more complicated: the direction and speed of the movement of matter.

And a little more philosophical is this: the basic order of the ordinary life world.

In general thinking, space-time is composed of space and time, space envelops time, and the passage of time is reflected in the movement of matter in space.

Therefore, it is often said that time is only a unit of measurement created by life, but in fact there is no concept of time at all, because they think that matter would still move even without time as a unit of measurement or concept.

This is a bold inference, similar to the fact that the sun rises tomorrow without it, and rejects the subjective recognition of nature by man, thus denying the existence of the concept of time.

The main point of this inference is that, objectively speaking, when nature has no one to determine the concept of time, matter is still moving according to its own laws, and what right does man have to stipulate the existence of nature in time.

However, with the development of science and technology, the nature of nature has become more and more insightful in the known universe and physics, and the real concept of time as a non-subjective existence has become a foregone conclusion.

As some civilizations entered the age of god-making, wormhole technology was used on a large scale, which indirectly proved the absolute rationality of the real existence of the basic concept of time.

Time and space, although divided into two concepts, time and space, are actually an inseparable whole.

The qualitative change of space can affect the change of time, such as in a black hole, but how to make the qualitative change of time affect space...... Its method has not yet been discovered.

What is certain is that, in terms of space alone, in general, space-time is a kind of high-level space division standard in the universe.

It is not known whether there are key factors that subvert and change time in some unknown and higher space, so as to be able to control time and space.

The study of time and space is related to the exploration and cognition of the deeper mysteries of this universe by advanced civilizations, and any life should aspire to it.

[You are reading a book with a solemn expression, and you are acquiring knowledge, and your progress is +1.7......]

Gu Yu carefully flipped through the treatises left by Morgana when she was an archangel Liang Bing and a tutor in the Super Seminary, and her expression was quite solemn.

Sure enough, worthy of being the god of Karl's time with the god of death, Morgana, as a cool ice period, is equally sharp in her academic indirectness in terms of good doctrine.

According to Gu Yu's limited inference, if it weren't for certain things, Liang Bing might have had more insights into time and space when he wrote this treatise.

Spacetime? Void?

Is there some kind of association?

Perhaps the void is a more advanced space-time, and generally speaking, according to the doctrine of earth-earth civilization, space-time can be interpreted as a four-dimensional space, and the void can be interpreted as a six-dimensional space.

However, this interpretation has certain cognitive limitations.

Three-dimensional is okay, four-dimensional, six-dimensional, these are the general generalizations of high-level space when the development of earth science and technology is not mature, and what it is actually like cannot be completely generalized without specific cognition.

Although compared with ordinary three-dimensional space, that is, a static space composed of pure length, width and height, space-time is more advanced, it is only because the concept of time is added to the static space, which makes matter move.

The real void is more unknowable than the basic space-time, and it is not entirely impossible to guess that the void is a more advanced space-time.

If you can study time and space, then there will be one more direction to study the void.

When Gu Zhengzheng was thinking like this, he received a prompt:

[You are reading a book, knowledge is being gained, progress +2......]

[Current entry: Time and Space]

[Progress Accumulation: 100%]

"Withdraw rewards."

[Progress settlement, rewards are being distributed......]

[Congratulations to the host, reward: Micro Temporal Suppressor*1.] 】

It's a prop reward, Gu Yu is slightly disappointed, he prefers to get a related aspect of the technology.

After withdrawing the reward, two palm-sized mechanical balls appeared in Gu Yu's palm, and he was slightly surprised after learning how to use them.

This thing, it seems...... Something.

He was going to experiment with the power of this thing, and in order to prevent anyone from suddenly coming to the library, Gu Yu went to the underground book storehouse.

Throw a ball not far away, estimate the distance, about two meters, and release the other ball as well.

'Whoa'

After a faint sound, the two spheres activated at the same time and floated, as if a laser connection appeared between the two spheres, and after a short connection, the laser disappeared, and a black area shrouded the space.

Gu Yu looked solemnly at the space between the two spheres, which seemed to be shrouded in darkness out of thin air, as if there was nothing special about anything else, but in fact, it was ......

Gu Yu carried a basketball out of the microscopic wormhole, and then threw it between the two balls.

Swish!

Something terrible happened.

I saw that when the basketball crossed the space between the two mechanical balls, most of the balls of the entire basketball seemed to be directly swallowed by an inexplicable force.

The remaining small part of the basketball fell to the ground as if it had been cut with a knife.

Gu Zhen looked at the position where the basketball was "devoured", and his eyes were like torches.

The orb wasn't devoured and disappeared, it was there!

To put it simply, the function of two spheres is to form a three-dimensional space that is absolutely isolated from each other based on the volume of their spheres.

What is a three-dimensional space that is absolutely isolated? That is, a three-dimensional space that does not exist in any time variable!

A three-dimensional space that is absolutely static and does not allow the movement of matter, this space is not in both directions with the surrounding space, and matter can only enter it from the surrounding space.

Once the matter enters this three-dimensional space, it will lose all its motion and will be in an absolutely static state, in a completely static space.

The reason why it looks like the space is so dark that you can't see it because the light can't travel through.

Light cannot travel in static space because light is both energy and matter.

Without the propagation of light, there can be no horizon, and without horizon, it means that there is no future, and without the future, it means that time is completely erased.

Miniature space-time suppressor!

Don't underestimate the three-dimensional space created by these two mechanical balls, which can be regarded as a local and small-scale dimensionality reduction attack method for real-world matter.

Unlike the two-way foil, which turns the entire galaxy into a flat painting, and uses the two-dimensional level as the target to reduce the dimensionality, these two spheres are aimed at the three-dimensional level, which means that the ......

Any matter that enters the third dimension will be dissolved by the concept of time, eliminating all its state of motion, and turning into an absolute static matter.

It's a terrible blow!

Gu Yu looked at his hands and decided to do an experiment.

He is undefeated, and in general theory, no matter what kind of damage he suffers, he will eventually recover because his data has been eternalized.

Although it is not as strong as the four generations of divine bodies, which can be restored immediately in the next second after being cut into foam, the recovery power is definitely not weak.

Gu Yu approached the two round balls, stretched out his left hand, and swung it out.

Swish!

His eyes widened, and his palm, part of his forearm, vanished.

disappeared into this small local space.

Although he could not observe the scene, he could be sure that that part of his body had lost its "state of motion", and after entering the three-dimensional space, he had no concept of time, and this part of his body seemed to be forever left in the three-dimensional space in front of him.

Like the part of the ball of the basketball, it turned into an absolutely static substance and stayed there.

But it's okay, it's not a big problem.

Gu Yu tried to mobilize dark energy to restore himself.

[Detected that somatic data is permanently lost and cannot be recovered.] 】
