The speed of light in a vacuum is constant, and it is the same for any observer.
Special relativity posits that the laws of physics are the same for non-accelerating observers and that the speed of light in a vacuum is constant for all observers, regardless of their relative motion. This theory by Albert Einstein also suggests that time and space are interconnected and can be distorted by gravity.
"E=mc^2" is part of Einstein's theory of relativity, specifically the mass-energy equivalence principle. It states that energy (E) is equal to mass (m) times the speed of light (c) squared. The theory of relativity encompasses not only this equation but also the principles of special and general relativity that describe the relationship between space, time, matter, and energy.
Essentially Relativity has two principles;the first principle is motion is "relative", A goes to B, has the same effect as B goes to A; the second principle is the speed of light c is a constant.
Einstein's theory of special relativity, proposed in 1905, states that nothing in the universe can travel faster than the speed of light in a vacuum. !!!!! But researchers at the CERN lab near Geneva claim they have recorded neutrinos, a type of tiny particle, traveling faster than the barrier of 186,282 miles (299,792 kilometers) per second.!!!!! << major breakthrough.. Because we have based almost everything on his relativity E=MC^2
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 relativity statement refers specifically to the speed of light in a vacuum.

There are two theories of relativity.1. Special Relativity (Einstein)2. General Relativity (Einstein)Einstein's theory of relativity posits that time is a dimension in addition to space, and that space and time have relative properties to one another. This is not commonly observed because it is only obviously apparent as an object approaches the speed of light (a constant and ultimate property in the theory.)Albert Einstein's special relativity and general relativity.Special relativity: a theory of the structure of spacetime. It was introduced in Albert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies". Special relativity is based on two postulates which are contradictory in classical mechanics: The laws of physics are the same for all observers in uniform motion relative to one another (Galileo's principle of relativity),The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light.General relativity: a theory of gravitation developed by Einstein in the years 1907-1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field are physically identical (for example when standing on the surface of the Earth). The upshot of this is that free fall is inertial motion. An object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and momentum within it. Some of the consequences of general relativity are:Time goes slower at lower gravitational potentials. This is called gravitational time dilation.Orbits precess in a way unexpected in Newton's theory of gravity. (This has been observed in the orbit of Mercury and in binary pulsars).Even rays of light (which are weightless) bend in the presence of a gravitational field.The Universe is expanding, and the far parts of it are moving away from us faster than the speed of light. This does not contradict the theory of special relativity, since it is space itself that is expanding.Frame-dragging, in which a rotating mass "drags along" the space time around it.
The postulate of general relativity states that the laws of physics are the same for all observers, regardless of their motion or gravitational field.
Einstein's theory of special relativity is expressed through two main principles: the principle of relativity, which states that the laws of physics are the same for all observers in uniform motion, and the constancy of the speed of light, which asserts that the speed of light in a vacuum is constant for all observers regardless of their relative motion. These principles lead to the famous equation E=mc^2, which relates energy (E) to mass (m) and the speed of light (c).
The Four Corners Monument is not accurately placed at the intersection of the four states.
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.
E=mc^2 was derived by Albert Einstein in 1905 as part of his special theory of relativity. The equation states that energy (E) is equal to mass (m) times the speed of light (c) squared.
