Comprendiendo la relatividad especial de Einstein

Abstract

The beginning of Special Relativity Theory is showed in this work and the Michelson-Morley experiment designed to demonstrate the presence of a medium in which light can move called "ether" in 1887 too. The failed experiment served to demonstrate that the speed of light is constant. Albert Einstein based on this result developed the Special Relativity Theory and its consequences are presented here in a simple way for the reader.
