How to explain and understand faster than light?

According to the new theory, the speed of light is not the ultimate speed.

There is an article in the scientific journal Nature. The researchers emitted a laser light wave and passed it through the cesium gas chamber, and found that the front segment of the wave had already drilled out from the other end before the tail of the laser light wave had fully entered the cesium gas chamber. The researchers said that the laser light wave traveled 310 times the distance that it could travel in a vacuum at the same time, and the researchers speculated that the cesium atoms may have changed the properties of light, so the laser light wave is faster than the speed of light in the vacuum.

The researchers say that the speed of light, at least in this laboratory environment, can be pushed further. "Our research shows that the notion that nothing is faster than the speed of light is wrong," Wang said.

Around the seventies, radio astronomers discovered that there were four dense extragalactic quasar radio sources in the universe. Extragalactic radio objects are sometimes thrown.

One or two pairs of radio nebulae, the radio electron source, which seems to have been caused by a violent **, separated from each other at high speed, and about half of them moved faster than the speed of light, even reaching 5 to 10 times the speed of light.

Velocity is relative, and the physical nature is independent of the frame of reference.

The new theoretical speed of light only limits the size of the horizon and does not change the physical nature. Thus the theory of relativity is an effect that can be applied to any particular wave velocity measurement.

The theory of relativity is to solve the physical phenomenon of high-speed moving objects, why they do not conform to Newton's laws.

There are two key points here: the concept of relativity, the difference between phenomena and physical essences.

By understanding these two points, the theory of relativity can be properly understood. A lot of people don't do it.

Some of the conclusions of the theory of relativity are that people misunderstand the theory of relativity.

Time is a parameter set by humans to express natural processes. It really should, as Newton said, that the uniform passage of time that is not related to other events, and the rest of the time, is not up to the definition. So, time doesn't turn back. There is no time travel.

The motion is relative, the time is uniform, the space is flat, and the light emitted inside the enclosed moving train is moving at the speed of light relative to the stationary frame of reference outside the train.

If we exceed the speed of sound, we catch up with the sound that the clock used to make, for example, when we start from the clock at 1 o'clock and hear the clock tell the time like this: 59 (min), 58 (min), 57 (min)...This is the popular explanation for going back in faster-than-light time.

Is it a wavelength greater than the speed of light or ?? Group velocity vs. phase velocity. The latter can be faster than light. But the former can't. The former can convey the message. There is currently a large number of people working on the faster-than-light problem.

Don't worry, you won't get younger than the speed of light, if you exceed the speed of light (let's not say it's impossible), then the time scale is the same for you as it was when you didn't exceed the speed of light, you will still die of old age, and you will just live longer than someone else's normal speed.

Our universe is made up of 4-dimensional space, when the star comes to the end of the inner core collapses, resulting in a huge gravitational force, so that it crushes time and space, a supernova explosion creates a black hole, and the huge gravitational pull will also make it impossible for light to escape, if you exceed the speed of light, it means that you may be able to get out of the black hole, imagine the energy of the star, you will understand that it is impossible to exceed the speed of light.

The speed of light is faster than the speed of light.

When the speed of an object approaches the speed of light relative to another object, the time of one object slows down relative to another, and the time change conforms to the Lorentz transform.

In the 70s of the 20th century, it was confirmed that the difference in the position of the solar eclipse at the same time observed by satellites and ground observatories was confirmed) The speed of light is the maximum speed known at present, and the kinetic energy of an object is infinite when it reaches the speed of light, so it is impossible to reach the speed of light according to the current human cognition, so the problem of the speed of light and the speed of light is not within the scope of physics discussion.

1.What does the universe need to be used as the driving force?

2.How does the universe communicate?

Both of these involve a problem of speed, power is the need for an energy substance to be pushed at a very large speed, and the speed carried cannot exceed the speed of the energy substance thrust back.

If the speed of communication wants to be instantaneous, then the speed of light is not enough, is there a faster speed than the speed of light. Gravity, whether the field force can be instantaneous, and the propagation speed of gravity and field force is also the speed of light.

Why is the maximum speed the speed of light? What limits the speed and what happens if you exceed it?

Later, I wonder if it is similar to the motion of an object on the Earth, where an object can escape the Earth's gravity and fly out of the Earth when it moves faster than the second cosmic velocity.

What is it that binds that makes the maximum speed not exceed the speed of light? Velocity is relative to time and space. The limit of speed is teleportation, which is to suddenly disappear into another dimension.

The so-called sense of time in motion is a quantity created to describe the process of moving an object from one space to another. So is faster-than-light traveling through space?

If it is more than the speed of light, if it is through space and teleportation, then there is no amount of time in the middle, only the size of the distance in space. There will be a new quantity coming out to describe the process.
