- it is a constant that is determined by Maxwell's equations for the speed of all electromagnetic radiation traveling in a vacuum.
- it is the same for all observers in all reference frames in special relativity. in agreement with Maxwell.
- nothing can travel faster than that speed. it is the speed limit.

Light is considered a constant in the theory of relativity because it travels at the same speed (approximately 299,792,458 meters per second) in a vacuum regardless of the observer's motion or velocity. This constancy of the speed of light is a fundamental postulate of Einstein's theory and is central to the predictions and equations of special and general relativity. It establishes a universal frame of reference for measuring time and space.

What is constant in special theory of relativity?
LIGHT
What theory did Einsteins theory of relativity replace?
Speed of light is constant, not the other things.
Where did Albert Einstein make the theory of relativity?
Albert Einstein gave the theory of relativity to prove that the speed of light is always constant and greatest......
What does special relativity say about the speed of light?
The speed of light is constant.
What is the speed of light per planet?
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.
Is density constant according to special theory of relativity?
Everything remains the same....I think
What is Albert Einstein's special theory of relativity?
The special theory of relativity was proposed in 1905 by Albert Einstein and states that:1. The speed of light is a constant, and2. All of the laws of physics are applicable within any given inertial reference frame.Special relativity deals with relative motion at a constant velocity, as opposed to General relativity. An inertial reference frame is formed by a group of objects traveling together at a constant velocity.For example: If you were in a car moving at a constant 60mph with no bumps in the road to disrupt you, you could throw a ball, perform experiments, and do virtually anything as though you weren't moving at all.Because of the speed of light being constant for all inertial reference frames, however, special relativity also implies that the faster an object moves, the slower time becomes for that object. Because of this, the theory of relativity is essential for determining speeds, distances and time at very high velocities.
What is the theory of realitivity?
There are actually two theories of relativity, the special theory and the general theory. In the special theory (1905) Einstein showed the relationship between energy, motion and mass. In the General theory (1912) he showed the relationship between acceleration, Time and gravity.
When was the theory relativity of light discovered?
In the beginning if 20th century.
If special relativity states that the speed of light is a constant how can refractive index be an indication of a change in the speed of light?
The relativity statement refers specifically to the speed of light in a vacuum.
What does the theory of general relativity mean in plain language?
The theory of relativity is the theory that states that light moves at a certain speed, and nothing can move faster than it. It is physically impossible.
Who wrote the Theory of Relativity?
Galileo Galile wrote "the Theory of Relativity", and Einstein wrote the General theory of relativity and the special theory of relativity.
