you are in a plane flying east with a head wind of 10 kph. The speed of the plane is measured by measuring the wind speed outside the plane and then adjusting for any head wind. Let's say you get a result (after allowing for the head wind) of of 200 kph.
Unbeknownst to you the arm of our galaxy called the milky way is heading west at 400 kph so really your speed is 200 kph backwards!
but THE universe is heading east at 400000 kph so your speed is now ... ummm ... a lot AND YOUR EYES START TO BURN :)
As a photon has a constant velocity in all frames of refernce and assuming technology advances to the point that the speed of a photon can be measured accurately. By measuring the speed of the plane relative to the speed of photons (measured simutaneously in all three dimensions) you should be able to derive the true speed of the plane regardless of the frame of ref? true or false :)
You will need to measure the speed of the photons simutaneously in 3 dimesnsions (east, west,south,north,up,down) as it may turn out the plane could be moving in any direction.
this would be similar to measuring the planes velocity realtive to the michelson morely experiment.
photons are completely diconnected from space
