Can the general theory of relativity be summarized in simple language?

The difference between special relativity and general relativity is that the former discusses the laws of physics between frames of reference for uniform linear motion, while the latter generalizes to frames of reference with acceleration and is widely used in gravitational fields under the assumption of the equivalence principle.

The research of the theory of relativity has made a drastic change in the common-sense concept of the universe and nature'Bending space-time'、'Four-dimensional space-time'A series of new concepts have refreshed all mankind's cognition of time and space. According to the theory of relativity, when the ruler of the time axis is added to the four-dimensional space, the speed of the object is inversely proportional to time. The faster an object in space moves, the slower time will be.

When the velocity of the object.

The first is "special relativity": the faster you go, the slower time passes. I believe that many friends who have some knowledge of physics should understand the meaning of this sentence. For an object moving at high speed, its time lapse is slower than that of an object moving at a low speed.

If an object can reach the speed of light, then time is stationary for it, a concept that does not exist at all, because the speed of light is constant relative to any frame of reference.

Then there is the "general theory of relativity": the greater the gravitational pull, the slower time passes. The so-called "gravitational force", that is, the gravitational force.

We know that when light passes through some massive celestial bodies, the original straight line propagation path will be deflected, which is due to the gravitational material, which distorts the surrounding space-time, so the path of light propagation is also distorted. The distortion of space-time caused by gravity makes the curvature of space-time larger, and the relative passage of time becomes slower and slower.

At first, this was only a prediction made by Einstein, but with the continuous progress of science and technology, this prediction has been continuously confirmed and has become an objective physical phenomenon. And once the gravitational pull of the object is so large that even light cannot escape (the so-called black hole), then the curvature of space-time here also becomes negative, that is, time will "go backwards". That's why some people think that "black holes" are a passage through time travel.

Summary. Hello, yes, special relativity is a special case of general relativity. The general theory of relativity was developed by Einstein on the basis of the special theory of relativity, which includes all the contents of the special theory of relativity, and adds concepts such as the theory of gravity and the curvature of space-time.

Therefore, special relativity can be regarded as a part of general relativity and a special case of general relativity. The special theory of relativity mainly studies the laws of motion of objects in a frame of reference with relatively stationary or uniform linear motion, including the relativity of time, the relativity of length, and the relativity of energy and momentum. The general theory of relativity further studies the influence of gravity on space-time, proposes the concepts of space-time curvature, black holes, etc., and gives the best and detection methods of gravitational waves.

Therefore, general relativity is a further development and expansion of the special theory of relativity, and it is a more in-depth and extensive field of relativity research.

Help me see if I'm right like this.

Hello, you are very right to divide it like this, so this theory of relativity is based on classical mechanics?

The theory of relativity is built on the basis of classical mechanics, but megalead is the theory of relativity that poses some challenges and modifications to classical mechanics. In the special theory of relativity, Einstein proposed the concept of relativistic motion relapse, that is, the motion states of different inertial reference frames are equivalent, and there is no "absolutely stationary" reference frame missed guess. At the same time, due to the invariance of the speed of light in the theory of relativity, the concepts of time and space have also changed, and time and space are no longer absolute and independent concepts, but are interdependent.

In the general theory of relativity, Einstein further extended the theoretical framework of the theory of relativity, put forward the concept of gravitational field and the curvature of space-time, and further revised the theory of gravity in classical mechanics and Newton's law of universal gravitation. The establishment and development of the theory of relativity has had a profound impact on the development of classical mechanics and physics, and enlightened scientists' understanding of physics and natural science.

The theory of relativity in a broad sense refers to the discourse of the concept of relativity, the most common of which are big-small, many-few, more with respect to 1,10 and less with respect to 100,10. The theory of relativity is commonly referred to as Einstein's theory of relativity.

The theory of relativity is all about the problem being discussed by a specific person from a specific angle, and the comprehensive discussion of the problem, no matter who it is, will agree that the objective discussion is the law of science, so there is no relativity theory in science.

Einstein's theory of relativity was originally used to explain what happens when the speed of motion is close to the measured speed. Because the velocity is relative, so all kinds of measured velocities are relatively close, so the theory of relativity should have a wider range of use.

Einstein's theory of relativity was discovered to explain the reason why particles moving at high speeds close to the speed of light do not conform to Newton's laws, but to Lorentz's laws.

For this reason, he made two assumptions: that the laws of motion in different frames of reference have the same mathematical form; The speed of light is the same in different frames of reference.

Special relativity says that there is a relativistic effect in an inertial frame.

Einstein's calculations deduced the results of slow clocks, shrinkage of rulers, and curvature of space, which are different from the traditional definitions.

But today, we find that the particle theory of light is not as solid as in Einstein's time, many phenomena can be explained by the law of waves, Einstein's hypothesis does not have universal laws, according to the current discovery, there can be a more adaptable theory of relativity and compatible with all theories, and its derivation only needs to make a little correction to the original theory of relativity, and does not need to make derivation assumptions.

When the bell moves away at close to the speed of sound, the bell heard is slower than the local bell because it takes time for sound to travel, and when the bell moves away at close to the speed of light, the bell seen is slower than the local bell because it takes time for light to travel, which is the essence of the bell slowness effect calculated by Einstein.

Light is a pure wave, and the relativistic effect is simply a measurement effect, an effect introduced due to the measurement of velocity. Einstein's theory of relativity is a theory of relativity that needs to be revised.

When Einstein deduced the theory of relativity, he did not rule out this effect at all, and there was a huge loophole in his derivation! Therefore, Einstein's theory is a theory that needs to be revised.

Special relativity is the theory that space-time is variable, but the speed of light is an absolute value, and general relativity says that inertial mass and gravitational mass are indistinguishable in a certain uniform space, which is called the equivalence principle.

At that time, people only recognized two kinds of fields - gravitational field and electromagnetic field, two representations - time and space, special relativity unifies time and space to obtain the basic Lorentz transform, and general relativity tries to unify the gravitational field and electromagnetic field, but Einstein did not do it, and later people did not completely do it, and now it is believed that there are still weak interactions and strong interactions, and weak interactions and electromagnetic fields have been unified, which is a unified theory for weak electricity, To a certain extent, the strong interaction and the weak electricity are also unified, but the gravitational force has not been completely unified, and some people want to use string theory to unify, but there is no experimental confirmation.

The most straightforward:

Special relativity is a new algorithm for time, displacement, length, velocity, and mass at the speed of light.

General relativity is a new algorithm for acceleration at near the speed of light.

The fundamental transformation is from the Galilean transform to the Lorentz transform.

With the people you like, with the people you don't like, it feels like the speed of time is different

We are creatures living in three-dimensional space, how can we see life in four-dimensional space, maybe they think we are boring. It's just that we don't know it, and it's scary to think about it, just like ants don't know that there are humans, it's the same thing. Because the ant is a two-dimensional space creature, it does not have two sense of direction, up and down, it is an alien that walks by smell, and we can't see it.
