We know that the universe is not vacuum. The average temperature of the universe is 3° above absolute zero. So some "aether" really exists, but that is not some gas with very low density, but stardust. (I know that aether was only concept for spreading of light in medium, but aether wind should exist.) So why we don't calculate with aether wind?
