Hi all"Direction of relative" does not parse. If you mean direction of motion, the answer is no, it matters not. In SR, time dilation relative to inertial frame F is a function of your speed relative to F, and speed, being a scalar, doesn't have a direction.
Halc can I please just clarify your points in regards to;Quote from: HalcAll clocks are affected by these things. Atomic clocks are in no way special in this way. Paint peels slower relative to a frame in which it moves faster.In regards to your first point does direction of relative away/towards have any bearing
I meant reverse. We're talking about a coordinate effect, and one can create a non-inertial coordinate system where some clocks run backwards. Look up the Andromeda 'paradox' as an illustration of this.Quote from: HalcThe coordinate rate of clocks can indeed be negative given a non-inertial coordinate system.are you stating rate of atomic clocks as negative as going in reverse or just slowing down ?.
Because if negative = reverse
are we not setting the scenario of the paint analogy going from peeling/flaking into the wind to. returning to the painted surface becoming shiny and new then liquid in the brush/sprayer to been back in the paint tin ?If my coordinate system orders the paint events that way, then yes. It's just a coordinate system.
