I will point out that this comment is factually wrong. The concept of luminiferous aether was discarded- not because of the discovery of Theory of Relativity, but becauae of the Michelson and Morley Experiment [0]. It is often joked about in High School and college Freshman Physics circles- Michelson received Nobel Prize in Physics [1] for a literally failed experiment.
