Meaning of Speed ​​of light

What is the speed of light:

The speed of light is considered a constant in nature by definition and a speed of 299,792,458 meters per second is calculated in a vacuum symbolized by the letter c.

The letter c for the speed of light originates from Latin celeritas which means speed or speed.

The importance of the speed of light is that it serves as a limiting speed for the universe and that it describes the property of electromagnetic waves according to Albert Einstein's theory of relativity published in 1916.

The expression E = mc² from Einstein's theory of relativity expresses the equivalence between mass and energy having a c (speed of light) as a constant of proportionality that links matter (m) and energy (E), therefore no information can reach an object faster than the speed of light.
