No, none of the postulates take the vacuum as a reference frame, which doesn't make sense since a vacuum doesn't have a measurable rest frame (there are no landmarks in a vacuum that could be used to measure the "velocity of the vacuum" relative to anything else).
One postulate does talk about the speed of light in a vacuum, but they're still talking about the speed of light as measured in an inertial frame--"in a vacuum" is just there to specify that it's not talking about a light beam moving through some measurable medium like water or air. Jesse ==. One postulate says: In vacuum the speed of quantum of light is constant. It is correct that ‘a vacuum doesn't have a measurable rest frame’. Why? Because in vacuum the speed of quantum of light is maximum and time is stopped, become infinite, unlimited. It means that the reference frame of vacuum is also infinite, unlimited. And infinity we cannot measure. But this doesn’t mean that infinite vacuum doesn’t exist. We have theories ( thermodynamics and quantum physics) which explain us the parameters of infinite vacuum. ===. Socratus Nope, all speeds are measured relative to a particular frame. Jesse If we measure the speed of quantum of light in vacuum from different inertial frames the result will be the *same* - constant.
