Of course, it is a rigorous proof, but Einstein did make the wrong conjecture, no one can be a saint or a sage, although he had more than 20 thoughts in his life to win the Nobel Prize, but there are also mistakes.
In terms of cosmology, Einstein's achievements are outstanding enough to win the Nobel Prize, but there is a very regrettable thing that when he pushes back to the equation of the universe, he introduced a cosmological constant, which means that the so-called universe is a static universe, although the theory of relativity deduces that the universe is in constant motion, but perhaps under the influence of classical mechanics, he did not hesitate to give up the beautiful theory to explain the so-called static universe, which became a regret in life. In 1948, a young man (I forgot whom) discovered the fact that the universe was expanding, which also explained many doubts about the universe, which Einstein later admitted.

It's not called conjecture, it's called assumption.
The so-called hypothetical premise is to take this premise as an axiom, first admit that it is true, and then carry out a series of deductions from the theory of relativity.
A series of physical theories are derived from these assumptions, which are consistent with actual observations, and the premises of these assumptions are not currently observed to be inconsistent with reality, then the physical theory is currently correct. Physics is built on such foundations.
Thus the constant speed of light is hypothetical, and this assumption is consistent with the present experiments, and there are no accepted experiments to disprove it, and the series of conclusions of the theory of relativity is also consistent with the present experiments. Therefore the theory of relativity is currently correct.

It is conjecture that the speed of light does not change, but it seems that the speed of light cannot be exceeded is not one of the conjectures???
When the object approaches the speed of light, the speed of the force can no longer catch up with the speed of the object, and there is no way to accelerate the object, so the speed of light cannot be exceeded.
Almost everything in the theory of relativity revolves around light, which is actually just a symbol of the field. If it is simple to go beyond the speed of light, it can be achieved by reducing the speed of light. But then you won't have to turn back time, because you don't have the speed to go beyond the field.
The force mentioned above is also part of the field.
Can you understand that?
-
The inability of the speed of light to be surpassed is not yet a rigorous proof, but it is consistent with experiments.
Einstein, of course, made mistakes. For example, he opposed quantum mechanics; He also doesn't believe that black holes calculated by general relativity really exist ......
-
The inability of the speed of light to exceed is a conjecture in special relativity.
On the basis of this conjecture, there are all the scale-down effects in the special theory of relativity, including space, time, velocity, etc., in this system, there is the expression vc.

From the mass-energy formula e=mcc, it is known from the theory of relativity that when an object moves, the mass becomes larger, and when the speed is close to the speed of light, the mass becomes infinite, then the energy it requires e=mcc is also infinite, so it is impossible to have infinite energy to accelerate the object to the speed of light....There is also a transformation factor through the theory of relativity, which is k = root number 1-vv cc, and when v>c is negative!

Yes, there is nothing completely right in the world, and it is believed that with the development of science, existing scientific theories will be overturned. This is the only way for the development of science (don't you hear that the back waves of the Yangtze River push the front waves, and each generation is stronger than the next?). )
-
It should be proved that m0 (root(1(vc)).
It's a bungalow. His erroneous conjecture was the cosmological constant.
-
It is a conjecture that has been carefully considered.
-
There are two basic principles of special relativity: (1) the principle of relativity and (2) the principle of invariance of the speed of light.

It was deduced by Albert Einstein.
And it has been experimentally proven!

Summary. The theory of relativity was proposed by the great scientist Albert Einstein in the 20th century, divided into broad and narrow senses, if you want to verify the theory of relativity, you must increase the speed of the object to the speed of light, but the current strongest ion collider can not meet this speed requirement, so the theory of relativity has not been accurately verified so far.
Hello subject, I have seen your question.
The theory of relativity was proposed by the great scientist Eins Ho Thanh in the 20th century, and is divided into broad and narrow and macro, if you want to verify the theory of relativity, you need to increase the speed of the object to the speed of light, but the current strongest ion collider cannot meet this speed requirement, so the theory of relativity has not been accurately verified so far.
Dear, my finish, if you can, please give a thumbs up, thank you. Five stars!

Absolutely. Moreover, not only the theory of relativity, but also any scientific theory can be wrong, which stems from the property that scientific theories must have—falsifiability. Falsifiability, as the name suggests, is provably false.
The theory of relativity is divided into special relativity and general relativity. The basic assumption of special relativity is that the speed of light does not change. It implies that information cannot be transmitted faster than the speed of light, and if this basic assumption is overturned, special relativity is wrong, because its entire theoretical system is deduced from a false assumption.
If special relativity is wrong, then general relativity is also wrong, because general relativity is based on special relativity.
Let's take a look at the general theory of relativity, which is a theory based on the curvature of space-time, and its basic equation, Einstein's gravitational field equation, is a curvature equation, which is used to calculate the correspondence between the energy momentum of matter and the degree of curvature of space-time. If space-time proves to be straight, i.e., there is no space-time curvature, then general relativity is wrong.
One might say that even if the speed of light is constant and the curvature of space-time is falsified, the theory of relativity is still correct to a certain extent, because its calculations within a certain range are accurate, so it only needs to be corrected. But I would say that if a theory is based on wrong foundations, it is wrong even if its calculations are correct. Applying within a certain scope only means that it can be used, but it does not mean that it is not wrong.
A geometrical theory of space-time used to calculate curvature is accurate, but if space-time itself is not curved, it is not a correct theory, but only a working theory.
The contradiction of fundamental physics now is that gravity cannot be quantized, strong, weak, and electromagnetic forces cannot be geometricized, and at least one of them needs to be corrected, and perhaps both of them need to be corrected, and we don't know which of them needs to be corrected, or how it needs to be corrected, and if it turns out that geometry is the wrong path, then the foundation of general relativity collapses. If space-time geometry is straight, then general relativity should only give approximations within certain ranges, because n-sided shapes are never equal to circles.

If you can't find a mistake, it must be right? Why are all sorts of second places always forgotten? Why is it less and less cool to watch blockbusters? The theory of sensory relativity takes you to understand the cognitive biases brought about by human simplification.
-
The theory of relativity cannot be at least a completely wrong theory, and there may only be parts of it that need to be improved, as in the case of Newtonian mechanics, limiting the scope of its application. The theory of relativity is divided into narrow and broad senses, and modern people are keen to explore how the general theory of relativity explains the universe. For example, in 2015, the Ligo probe successfully detected gravitational waves, which is a verification.
-
I think it's very probable, because the author of the theory of relativity was quite old at that time, and his theory was also wrong.
-
I think that if you look at it on another level, the theory of relativity may be a wrong theory, but for now, the theory of relativity is a correct theory.
-
Anything is possible, and perhaps some theory in the future will overturn the theory of relativity.

The drop of an apple led Newton to discover gravitation, but in general relativity, this description of force can only be said to be an approximate description, such as the motion of a celestial body around a star, and the gravitational force in the face of a massive celestial body is not very accurate.
I suggest you go to "Feynman on the Theory of Relativity", which is very detailed. I had almost forgotten about the special theory of relativity that I had studied last semester, but if I were to prove it now, I would first think of the two most basic assumptions: the invariance of the speed of light and the principle of relativity. >>>More

LZ: Hello!
Relative mechanics is based on the theory of relativity, which is very different from classical mechanics in that it denies that space-time is absolute, and many effects cannot be explained by classical mechanics, such as: Mercury's perihelion precession, radar's echo delay, etc., and it also points out that there is an inseparable relationship between the energy and mass of matter (e=mc 2). The fundamental laws of classical mechanics are Newton's laws of motion or other mechanical principles related to Newton's laws and equivalent, which are mechanics before the 20th century and have two basic assumptions: >>>More
The key point is that the source of the internal stress of any matter is nothing more than the four fundamental forces, and the propagation speed of these four fundamental forces is the speed of light, so the propagation speed of the internal stress of matter can only be lower than the speed of light - there is no such thing as hard as you imagine. >>>More
