Can gravity change space and time?

Introduction: There are many theories and speculations about gravity, gravitational waves and gravitons. So is the unified theory of gravity and the other three forces. Let's take a look at the exploration of these problems.

In-depth analysis of the nature of gravity, gravitational waves and gravitational fields and a unified overview of the four basic forces.

Two key points: 1, the relationship between gravity and other basic forces, and electromagnetic force is chosen as the breakthrough here. 2. Unified interpretation of the four basic forces.

Furthermore, in the physical universe book "Change", the understanding of relativity is actually much more macroscopic than that of quantum mechanics. Therefore, it is necessary to constantly increase the explanation of quantum mechanics. To prove that Einstein's general theory of relativity can be in harmony with the other three basic forces!

So we have a lot to discuss, and the coverage has reached an unprecedented breadth, which is also the reason why this topic is scary. If it's just a scary topic, that's fine. Behind the topic is a headache for us humans. Let's walk into this magical world together!

Of course, the topics to be discussed in this chapter are supported by the previous knowledge theory. First of all, from a philosophical point of view, I said at the beginning that things are generally related and the connection is conditional. Then, as the four basic forces of the universe, how can they be unrelated? What about disharmony?

But why have we failed so many times and failed to unify the four basic forces? Every failure paves the way for the next success. With more preparation, new conditions and new ideas, the problem will be solved.

We now know that space-time is the synthesis of time, matter and space. And the origin of gravity is time and space! In other words, gravity is a space-time property.

So obviously, the four basic forces, namely gravity, electromagnetic force, strong force and weak force, are the most fundamental ones.

All previous theories have not discussed who is the most important and fundamental of the four basic forces. In other words, gravity is the most fundamental and important force in my theory.

Except gravity, the other three forces have been unified in the gauge field theory. But in fact, gravity still has an effect on particles in the quantum field. It's just that we usually think that this gravitational effect is very small within the scope of quantum mechanics, so we ignore it.

Obviously, this kind of neglect is not rigorous. Moreover, it is considered that parity non-conservation, uncertainty principle and spontaneous breaking are all related to gravity. Gravity acts as a "disturbance".

In other words, gravity is a basic force in the universe and a space-time property. Is there a wider force than this? Don't! In other words, the other three forces belong to the category of time and space, and the fundamental embodiment of the essence of time and space is gravity.

From a philosophical point of view, when dealing with the relationship between various forces, we often take gravity as the main contradiction to analyze various phenomena and States. The other three forces are considered as secondary contradictions.

Start with the latest research. Let's first look at what gravitational waves are and how gravity is discovered. Let's take a look at the following picture about gravitational waves.

From the pictures, we know that gravitational waves are ripples of time and space. It propagates outward from the radiation source in the form of waves and transmits energy in the form of gravity radiation. In 19 16.

Einstein predicted the existence of gravitational waves based on general relativity. The existence of gravitational waves is the result of Lorentz invariance of general relativity, because it introduces the concept of finite propagation speed of interaction, that is, the speed of light.

In contrast, gravitational waves cannot exist in Newton's classical theory of gravity, because Newton's classical theory assumes that the interaction and propagation of matter are infinite.

On February, 2065438 1 1, LIGO Scientific Cooperation Organization and Virgo Cooperation Team announced that they had detected the gravitational wave signal from the merger of double black holes for the first time with the advanced LIGO detector.

In the early morning of June 16, LIGO Cooperation Group announced: 201513: 38: 53 February 26th,

(UTC), two gravitational wave detectors located in hanford, USA and Livingston, Louisiana detected a gravitational wave signal at the same time; This is the second LIGO.

The second gravitational wave signal detected by human beings after the first gravitational wave signal was detected on September 20 15 14. [2]

In order to let everyone know more about the theory to be told to you later, it is necessary to know the specific detection of gravitational waves. Let's look at the text discussed by Dr. Liu Boyang in the picture above.

Two stellar black holes with solar masses of 26 and 39 respectively. Rotate each other and finally merge. The merger of black holes produced a very big collision, so gravitational waves were observed on our distant earth.

This process is divided into three stages.

The first stage:

The gravitational wave frequency of the two black holes starts from 30Hz, which is a relatively low frequency band in gravitational wave astronomy, but it means that the orbital frequency of the black holes is 15Hz. More specifically, these two black holes are 30 and 36 solar masses respectively. Each line has a radius of about 1000 km and a distance of about1000 km. 15 revolutions per second.

The second stage: when two black holes merge, the gravitational wave frequency reaches 100Hz and the orbital frequency is 50Hz, that is, 50 revolutions per second. At this time, the two black holes are almost integrated, and the distance between the "centers" of the two black holes is about 200 kilometers.

The third stage: the merged black hole continues to twist and oscillate, forming a new and rotating black hole. The mass of this black hole is 63 solar masses. About three solar masses disappeared in the collision and spread outward in the form of gravitational waves!

Let's go back to the original theory that gravity is changing-gravity is a space-time property. Space-time is the space-time of energy. Therefore, without the disturbance of massive celestial bodies, it is difficult to detect the ripples in time and space. Although we are in time and space. There is a feeling of "I don't know the true face of Lushan Mountain, but I was born in this mountain".

Here again, gravity is not produced by the bending of time and space, but by the nature of time and space-it is time and space that produces gravity!

Bending is an illusion. Because the back of time and space is curved, gravity can bend time and space! But it's not the bending of time and space that produces gravity! It's space-time energy, it's space-time gravity! This is why everything with mass has gravity. Because gravity is a spatio-temporal property, any object with mass can't escape this spatio-temporal law. This is true from the macro level to the quantum level.

So obviously gravitational waves are ripples in time and space, so what is a gravitational field? Space-time is a gravitational field, and obviously such a gravitational field is a global field. This is fundamentally different from the existing definition of gravitational field.

In fact, it is not difficult to understand that gravity is a spatio-temporal property, and the gravitational field is naturally a spatio-temporal property. The difference between them is the different expressions of space-time online, surface and body, but they are all out of the same space-time nature!

Therefore, the definition of gravitational field is that gravitational field is a global spatio-temporal property, and its field strength is directly proportional to the distribution of energy and matter and the speed of motion.

Key words: wholeness, material energy distribution, movement speed, proportional relationship.

The so-called wholeness means that the gravitational field is theoretically the nature of the whole time and space, so its breadth means that there must be a gravitational field where time and space are located.

How to understand the distribution of material energy? The distribution of material energy in the whole space-time is uneven, and the strength of gravitational field is naturally different. Although it is a global field in theory, it permeates the whole universe. But from the perspective of differential thinking, due to the heterogeneity of material energy, we can divide the global field into n local fields.

However, it should be clear that this division is artificial, and it is envisaged to better study the theory of gravity.

So what is the relationship between local field and local field? Obviously, it is directly proportional to the distribution of matter energy and inversely proportional to the square of the distance between them.

Let me remind you that gravity and gravitational field travel at the speed of light. This has been discussed in the previous chapter.

Many people may ask, why not add the description of "inversely proportional to the square of distance" to the definition of gravitational field, but add such a description to the local gravitational field.

As I said above, the gravitational field should be a global field, which is a space-time property. Only when you measure the gravity of a specific object, a specific celestial body, and a specific cluster can you tell the distance between them-that is, the distance between objects. That is to say, there are at least two particles, A and B.

In this way, we introduce Newton's gravity theorem: any two particles attract each other through the force in the direction of the line. This gravity is directly proportional to the product of their masses and inversely proportional to the square of their distance, and has nothing to do with the chemical composition of two objects and the type of medium between them.

The mathematical formula is: f = GMM/r 2. G is the gravitational constant, which is equal to g = g = 6.67×10n m m? /kg？ .

Obviously, Newton's theory is a "static" theory of gravity and an absolute theory of time and space. Einstein's general theory of relativity is a "dynamic" theory of gravity and a relative theory of time and space. This is AI's advanced point.

In other words, Newton's theory of gravity has limitations and is not suitable for high-speed moving objects. Due to the relativistic effect, the mass of high-speed moving objects will increase. If Newton thinks that mass does not change with the speed of motion, then he naturally won't realize it.

That's why I redefine quality. Is to return quality to the essence of energy. Then define mass by energy. That is, mass is the physical property of an object in relative space-time, and the energy contained in an object is a measure of its mass.

In this way, mass is always placed in the mass of relativistic spacetime. So Newton's theorem of universal gravitation is wrong?

In fact, it can't be said that it is wrong, insufficient and inaccurate. This is what human beings must experience in the process of understanding the universe.

Gravitational field, the origin of gravity is time and space. Gravitational waves are ripples in time and space. The concept of electromagnetic wave should be put forward here. Gravitational waves and electromagnetic waves are different. Gravitational waves are ripples in time and space, and electromagnetic waves are generated by electromagnetic fields. Their relationship will be analyzed and discussed in detail later.

The biggest problem now is that the origin of gravity, gravity and gravitational waves has been clarified. So we ask: Do gravitons exist?

The above describes the process of gravitational waves being detected. Black holes will lose part of the mass of the sun in the process of merger, oscillate in the form of energy, and are detected by us, that is, gravitational waves.

In other words, space-time is also energy space-time, and the origin of gravity and gravitational field is also energy space-time. It is a spatio-temporal property. Gravitational waves are caused by great changes in time and space, unlike electromagnetic waves.

The propagation of gravity does not need a medium, which means that the propagation of gravitational waves does not need a medium. Space-time is an energy space-time, and the transmission of energy needs no medium, which is why the transmission of gravity and gravitational waves needs no medium. But they travel at the speed of light, not faster than light!

Otherwise, we are trapped by a rhetorical question. The rhetorical question is: if gravity and gravitational waves travel long distances, that is to say, they don't need any time to travel, can humans still detect gravitational waves?

Obviously impossible!

Because the origin of gravity, gravitational waves and gravitational fields all return to energy space-time, the so-called graviton is the smallest unit of energy-energy quantum.

So what is the smallest unit of energy and does it exist? The current research does not exist! That is to say, there is no minimum energy unit, and there is no such definition!

Therefore, the exploration of gravitons needs to be cautious, and it is very likely that the bamboo basket will draw water with a sieve. Because gravity is a space-time property. Space-time is energy space-time, and everything is the matter that constitutes energy space-time.
