There is no such thing as a "speed of light theory". And entanglement is NOT closely related to the speed of light.Entanglement DOES give the impression that certain things act instantaneously over great distances - but it seems that this will always happen in such a way that it is NOT possible to send information faster than light, or to the past.
The speed of light is a number. It was a theory before it was measured. After it was measured, and the prediction was found to be correct, it was no longer a theory nor a hypothesis. It became a "physical constant".
The speed of light is the same for every observer everywhere. That is a fundamental tenet of the theory of special relativity (and everything based on it, such as the general theory of relativity and quantum field theory). To date no violation of the consistency of the speed of light has been measured. By the way, this does not say the speed of light is the maximum speed, just that the speed of light is constant, so the possible discovery of faster-than-light neutrinos does not invalidate this.
No, the speed of gravity is the same as the speed of light, according to the theory of general relativity.
Neither, mass can never reach the speed of light, this question also contridicts the theory of realativity.
Light moves at a constant speed in a vacuum because of the properties of space and time, as described by the theory of relativity. According to this theory, the speed of light is a fundamental constant and does not change regardless of the observer's motion or the source of the light.

You can't travel at the speed of light. It might be possible, in theory, to approach it, but not quite to reach it.
The constant speed of light in the theory of relativity is significant because it serves as a fundamental constant that underpins the theory. It implies that the speed of light is the same for all observers, regardless of their relative motion. This principle leads to the concepts of time dilation and length contraction, which are key components of the theory of relativity.
The relationship between the speed of light, time, and space is described by the theory of relativity, specifically in Einstein's theory of special relativity. This theory states that the speed of light is constant for all observers, and as a result, time and space are relative and can be affected by an object's motion and gravity.
The speed of light is a constant in the special theory of relativity, as it is the same for all observers in inertial reference frames. This constant speed of light serves as a fundamental principle in shaping the structure of spacetime and the behavior of physical laws in the theory.
Nothing can travel faster than the speed of light in a vacuum, according to the theory of relativity.
No, according to the theory of relativity in physics, information cannot travel faster than the speed of light in a vacuum. This is because as an object with mass accelerates towards the speed of light, its energy increases towards infinity, making it impossible to exceed the speed of light.
