What I want to know is... if objects apparently traveling away from us at high speed, shift the light towards the red end of the spectrum ( and towards us, the blue )... surely the same effect would be experienced if the distant object was in fact stationary (hypothetically) and it was us traveling away/towards from the object at high speed? so when we calculate the distance and speed of distant bodies in the universe with redshift... how do we know that the entire spectrum shift can be attributed to the velocity of the receding body alone? surely it can't be so.. so we must be measuring the speed of it, in relation to us...a combination of both objects speeds, and the resultant spectral shift...a culmination of these too. would this not create the illusion that it had moved further/faster than it actually has? I am clearly not a physicist and hope I am not just chatting boll*ks, but another example to help me...if there were 2 objects on a frictionless surface which were placed near to each other.. and we had a point of view shot from one of these objects.. . If they were both pushed in different directions at different speeds...it would appear to us that we were still stationary and the other was moving away at a misinterpreting speed..would it not?! but surely if we could measure the objects in relation to another central object/s then we could resolve the components and work out, not how far or fast we are moving away from each other, in relation to each other..but how fast we are actually moving from each other from a point in space/time, and therefore actual velocities/rather than apparent.
Anyway, I am just a business student and likely gone horribly wrong somewhere (probably the start) but wouldn't pester you serious folk if I hadn't tryed looking it up already!
Thanks ...Ollie
