The [[Michelson-Morley experiment]] in 1887 failed to detect the aether. [[Henri Poincaré]] conjectured that the aether may be unobservable, and invented special [[relativity]] based on the notion that the aether may be superfluous. [[Albert Einstein]] published conflicting opinions on whether the aether exists.

Today we have no firm answer on whether the aether exists or not. [[Quantum electrodynamics]] (QED) teaches that when light goes through a [[vacuum]], it is really going through a sea of virtual particles. Cosmologists say that the vacuum is really filled with ''dark energy'', and it is unknown whether that has any relation to the aether concept. The pre-relativity aether theory has been superseded, but the precise nature of the aether is an open question.

However, their is no evidence that it does exist and fails to satisfy the burden of proof.
