The question of the speed of light, the doubt that the speed of light cannot be surpassed

This is a hypothesis that is difficult to deduce, there is an inference.

There is a principle in the theory of relativity called the principle of invariance of the speed of light, which says that the speed c of light (in a vacuum) is constant, and it does not depend on the speed of motion of the luminous object.

On the surface, the invariance of the speed of light seems to conflict with the principle of relativity. Because according to the synthetic law of classical mechanical velocity, the speed of light should be different for k and k, two coordinate systems that do relatively uniform motion. Einstein believed that in order to admit that these two assumptions do not contradict, it is necessary to re-analyze the physical concepts of time and space.

In 1905 Albert Einstein pointed out that Michelson and Morey's experiments (see .

In fact, the whole concept of "ether" is redundant and the speed of light is constant.

From the two basic principles of relativity, all the contents of special relativity, such as the coordinate transformation and velocity transformation of the theory of relativity, can be directly derived. For example, the change of speed contradicts the traditional law, but practice has proved to be correct.

In addition, if there is an enclosed space with an absolute vacuum, and two objects are moving, both objects will see the speed of light.

The speed at which light or electromagnetic waves propagate in a vacuum or medium. The speed of light is the maximum speed at which an object can move in nature. It is independent of the speed of the observer relative to the light source, i.e. the speed of light measured in the inertial frame relative to the stationary and moving light source is the same.

The value of the speed of these constants is based on the Earth as a reference system by default, according to the landlord, the sound speed is not 340m s, you have to add the speed of Mars relative to the Earth?

It's just a convention. "Velocity varies with the frame of reference", so all values of velocity have a frame of reference, and these constants are by default relative to the Earth.

But the speed of light is the exception. The invariance of the speed of light cannot be explained in Newtonian kinematics.

According to existing theories, the speed of motion of an object cannot exceed the speed of light. Then we know that all moving objects in the world cannot exceed the speed of light, according to Einstein's theory, when all objects are close to the speed of light, the mass of the object increases, and the closer to the speed of light, the mass is close to infinity. So why doesn't the photon mass increase?

The explanation of Einstein's theory is that photons have no rest mass. In other words, the photon will disappear forever and move far away. At the same time, the speed of the photon never changes.

So how are photons generated? There is an existing light source that constantly radiates photons outward, and since the photons have no mass, the quality of the light source will never decrease. So where does the photon energy come from?

The light source, of course. The problem now is that photons only have energy and no mass. So what exactly is the energy of a photon?

If the photon is a granular bridge, it will penetrate everything at the speed of the photon, because the speed of light is the maximum speed, but the reality is that the photon cannot even penetrate a piece of paper. It can be said that the photon is not a particle, it not only has no rest mass, but also does not have a moving mass, otherwise it will have an impulse and a powerful effect will be presented.

If it is said that photons are pure energy. So who can give a definition of pure energy! Can energy move remotely? If energy can move, then it can be achieved across the mountain. The question is, can this be achieved? This is a significant violation of Newton's third law.

Wake up! Those who also believe that the speed of light cannot be surpassed. In fact, light is a phenomenon.

Any object that is heated to a certain temperature will emit light, and light is a phenomenon when heat transfers heat radiation. It's like when we knock on a steel pipe, the sound is transmitted from one end to the other, and the substance in the steel pipe sends this "sound" from one end to the other, and there is no sound that binds this "sound" together and moves from one end to the other. In the same way as light, the transmission of light does not need to be kidnapped with photons to move at the speed of light, in fact, the speed of photons is extremely limited, and the phenomenon of light, like sound, is transmitted through many photon relays.

First of all, there is nothing in the world that can exceed the speed of light.

If you have studied Newtonian mechanics, this problem is not difficult to solve.

According to Einstein's theory of relativity, when the speed of an object is infinitely close to the speed of light, its mass will be close to infinity, and the mass is infinite, according to Newton's second law: a = f m, if you want to accelerate the object again, you have to apply a very large force to it, the closer to the speed of light, the greater the force required, and in the end, the force required will be infinite. Even if there is, it reaches the speed of light at most, and after reaching the speed of light, there is an infinite force, and the acceleration is also 0, because the mass of the object is also infinite.

It can only be roughly explained in this way, because of the limited conditions, many formulas cannot be transmitted.

As for the matter that the above mentioned is faster than light, it is not that matter is faster than light, but that light has become slower, and light travels at different speeds in different matter, and by using different substances, scientists have been able to slow down the speed of light to within two digits. Remember, the speed of light here is c = 299792458 m s

Is the speed of light in place? Scientists have found that these speeds in the universe are far greater than the speed of light!

Faster-than-light things were like the other side of the timeline when the universe was born, and not only space has n-dimensions, but time also has n-dimensions, and the two are interconnected.

A: It's not that it can't, it's that it can't be reached. The speed of light is the maximum speed of motion of an object in nature that has been discovered so far.

The mass of the object will increase with the increase in velocity, and when the speed of the object is close to the speed of light, its mass will tend to infinity, so it is impossible for an object with mass to reach the speed of light. Only photons with zero rest mass are always moving at the speed of light. The speed of light is superimposed on any speed, and the result is still the speed of light.

The synthesis of velocity does not follow the laws of classical mechanics, but follows the relativistic laws of velocity synthesis.

If you are interested in this, I suggest that you can read more physics similar to "The Universe in the Shell" and "A Brief History of Time", which is still unclear at the speed of light.

The theoretical knowledge currently learned is yes! The speed of light is the fastest!
