SUMMARY
Einstein's Theory of Relativity establishes that the speed of light (c) is absolute in a vacuum, regardless of the observer's reference frame. While energy and momentum of light are relative, the constancy of light speed is a fundamental postulate of the theory. The discussion highlights a common misconception regarding Einstein's quote "everything is relative," clarifying that the speed of light remains invariant across all frames of reference. Furthermore, it is noted that Einstein initially considered naming his theory "The Theory of Invariants."
