If there are 2 objects emitting light to each other and the light fills the spacetime between them and then that spacetime expands the waveform becomes stretched. However, if the middle of the spacetime between the 2 objects has yet to have light enter it from either object and that spacetime expands, the light will take longer to reach the objects from each other but the wavelength will not have been stretched.
I am no expert but that is my understanding. Please let me know if i am just stupid, or could redshift in fact be entirely unreliable?
