The special theory of relativity is a theory proposed by Albert Einstein in 1905 that illustrates light and matter propagation at high speeds.
Einstein’s theory is based on two main ideas:
The principle of relativity: stipulates that the law of physics is invariable for anything that is in constant motion.
The principle of speed of light: stipulates that the speed of light is also constant for any object in any point from which it is being referred. This means that it the same for various observers regardless of their movement in relation to the source of light. Einstein established this principle after noticing a rational flaw in
