The limit of the speed of light? Why is the speed of light the limit of all speeds?

Newton's laws are not applicable under the conditions of high-speed, microscopic, strong gravitational fields. The strong gravitational field of a black hole can attract light, but the strong gravitational field of a black hole can also distort time, and the speed at which light is drawn into the black hole is still the speed of light.

No, Newton's laws apply to macroscopic low-speed moving objects, and relativistic mechanics should be used when the speed of light reaches the speed of light.

When an object is close to a black hole, it can no longer maintain its original form, it will be torn apart by the gravitational pull of the black hole, and the object in the black hole may theoretically have a speed that exceeds the speed of light, because in a black hole time is theoretically arbitrary and there is only one direction...

Newton's laws only apply in a macroscopic sense, i.e., at low speeds. To the speed of light, the theory of relativity is used.

A black hole is the internal collapse of a star at the end of its life, so that it gathers a huge amount of mass in a very small space, and the gravitational force is so strong that even light cannot come out, so it is called a black hole. I'll be able to answer your questions here.

Newton's second law is macroscopic cognition.

The speed of light in a vacuum never changes.

Take a look at a brief history of time.

I don't understand. I know that black holes are faster than the speed of light.

According to Einstein's theory of relativity.

The speed of light in a vacuum is the maximum speed of motion of an object in nature that has been discovered so far.

The speed of light is independent of the speed of the observer relative to the light source, i.e., the inertial frame relative to the rest and motion of the light source.

The measured speed of light is the same.

The mass of the object will increase with the increase in velocity, and when the velocity 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 classical mechanics.

and obey the law of relativity's velocity synthesis.

The definition value of the speed of light in vacuum: c0=299792458m s.

But some scientists believe that there are three things in the universe that could be faster than the speed of light.

The first: light pulses.

A pulse of light is a light source that emits light intermittently at certain intervals, and in a vacuum, the light pulses measured at different locations seem to propagate at an incredible speed.

The second: quantum entanglement.

Gerald, professor of physics at Baylor University.

Cleavell argues that in the phenomenon of "quantum entanglement," information appears to travel faster than the speed of light.

The third type: the rate of expansion of the universe.

Two points in the universe that are far enough away to expand and regress "at a speed of light" that exceeds the speed of light does not violate the theory of relativity. At the same time, it also means that if two points are far enough apart, light cannot travel from one point to another, because in a finite time, the distance traveled by light is always less than the distance increased by expansion.

Fourth: wormhole crossing.

A "wormhole" is a thin tube of space-time that connects distant regions of the universe. Dark matter.

Keeps the exit of the wormhole open. Wormholes can put parallel universes.

Connect with the baby universe and offer the possibility of time travel. A wormhole may also be a space-time tunnel connecting a black hole and a white hole, so it is also called"Gray Channel"。

The speed of light, 299792458 m s, the speed of all matter cannot exceed this value, it is the maximum speed in nature, the speed of light does not vary according to the reference frame, no matter how you do how to measure, the speed of light in a vacuum is 299792458 m s, neither big nor small.

The above is the premise of Einstein's theory of relativity, if one day it is found that the speed of an object is greater than the speed of light, then it is time to declare the theory of relativity fail. However, after so many years of time testing, I still believe that the theory of relativity should be infallible, and it is great, just like classical Newtonian physics, applicable within a certain range, and is an approximate result of the theory of higher forces. I think that people who have just studied the theory of relativity will be very curious about the relativistic effects such as time dilation, shorter size of objects, and greater mass, but people tend to ignore one of the two major premises of relativity:

Why does the speed of light in a vacuum change? Why can't it be bigger or faster?

Even Einstein couldn't answer this question, so he simply took it as an axiom, the principle of the invariance of the speed of light. Of course, our IQ is not as high as Einstein's, and sometimes we don't even seem to understand the theory of relativity, so if we have to answer this question, we can only imagine it whimsically and entertain

In my opinion, it is the nature of the universe that determines that the speed of light is so large, and our universe comes from a dense singularity, and the initial nature of this singularity determines that the value of the speed of light is 299792458 m s, which can neither be more nor less. If the universe is not only three-dimensional, there are also high-dimensional, and there is more than one singularity, then these singularities can produce multiple universes, different singularities, their size, mass, temperature, type, etc. are different, so the physical properties are not the same, resulting in the speed of light in their respective universes is also different, and the speed of light in our universe is 299792458 m s.

If you continue to ask about the properties of the singularity and determine the speed of light, then you will have to wait until human beings can enter the high-dimensional space and personally study the process of a singularity. Of course, the way to enter high-dimensional space is to speed faster than the speed of light, so that you can leave three-dimensional space and enter high-dimensional. Just like the first cosmic velocity of the earth, beyond this speed limit, you will leave the earth and enter space.

And this velocity is calculated by the physical properties of the earth, such as mass, volume, rotation, etc.

Therefore, if you want to know why the speed of light is so large, you still need to study the process from a singularity ** to the birth of the universe to come up with an explanation. Otherwise, the constant speed of light will only forever be an axiom that cannot be falsified.

Since the speed of light is the limit of the speed of the universe, why is the expansion rate of the universe greater than the speed of light?

Because the speed of light is very fast, reaching 300,000 kilometers per second, and time stands still when the speed of light is reached, the speed of light is the ultimate speed in the universe.

According to Newton's second law, when an object with mass travels at the speed of light, its mass increases infinitely. Only objects in the universe that have no mass can reach the speed of light, where photons are objects without mass.

Because the speed of light is very fast. With the current level of human technology, the speed of light is the fastest in the universe. So it's the ultimate speed.

First of all, the speed of light is the ultimate speed in the universe, and this speed refers to the speed at which information and energy travel. As for why the speed of light is the fastest, and the speed of light is slow relative to the vast universe, current physical theories cannot provide a scientific explanation.

If we look at it from the perspective of the anthropic, because the speed of light is the upper limit of the speed in the universe, and the mass of electrons happens to be so large, the universe will exist, life will evolve on the earth, and human beings will ask such questions. If this were not the case, the rules of physics would have become completely different, and then it would be possible that the universe would not exist at all, and life on Earth would not have existed, so there would be no such problem.

Although the theory of relativity limits the speed of information and energy to the speed of light, and the universe is so large, this does not mean that we cannot achieve interstellar or even intergalactic travel. The speed of light remains constant relative to any frame of reference, and this peculiar property causes a very peculiar time dilation effect. Using the principle of slow clocks, humans can fly long distances in their lifetime and achieve interstellar travel.

In addition, wormholes predicted by general relativity can also enable long-distance interstellar travel.

If you talk about the earth, there is no speed faster than the speed of light at the moment, I mean, at present, before, I read a book, the book said, when the speed of light is exceeded, you can space-time, you can also reach absolute zero, if theoretically, it is like this:

The principle of accumulation of velocity is based on the theory of classical physics, and is not suitable in such a motion of light.

According to the relativistic velocity addition formula:

v=(v1+

v2)/(1+

v1*v2/c

v1 is the velocity a, v2 is the velocity b, c is the speed of light, if v1 = v2 = c, substitute the formula to get v=c

In v1 and v2, as long as one is equal to the speed of light, no matter how much the other velocity, the result is always v=c

In conclusion, the maximum speed in the world is the speed of light, and there is no faster speed than the speed of light.

But to be honest, I always feel that nothing is impossible at this time, just like aliens, saying that there is no air and water on other planets in the banking system, but they don't have to rely on water and air to survive like humans? I think the words on the first floor are simple, but they still make sense, what is impossible? Who knows 1,000, 10,000 years from now?
