what is the special relativity in relation to it?
The speed of light in vacuum "c" featured as a fundamental constant, also appearing in contexts unrelated to light.
Speed of light
Using this and the principle of relativity as a basis he derived the special theory of relativity, in which the speed of light in vacuum "c" featured as a fundamental constant, also appearing in contexts unrelated to light.
who discovered the speed of light in a vacuum Witelo what is the numerical value of it? As a dimensional physical constant, the numerical value is different for different unit systems. how important is it in the field of physics? It is independent both of the motion of the wave source and of the inertial frame of reference of the observer. were there any experiments conducted to discover something faster than light? Yes, but they do not travel fast than light who did such experiments? UNANSWERABLE what is its part in spaceflights? There is a brief delay from the source to the receiver, which becomes more noticeable as distances increase; was significant for communications between ground control and Apollo 8

Speed of light [SEP] Special relativity
In 1905 Einstein postulated from the outset that the speed of light in vacuum, measured by a non-accelerating observer, is independent of the motion of the source or observer. Using this and the principle of relativity as a basis he derived the special theory of relativity, in which the speed of light in vacuum "c" featured as a fundamental constant, also appearing in contexts unrelated to light. This made the concept of the stationary aether (to which Lorentz and Poincaré still adhered) useless and revolutionized the concepts of space and time.
