The "redshift" involves a reduction in energy. But it also means less vibrations per second. Now, if I wave my hand once a second, you would expect to see this as one wave per second, not more or less. As far as I know, this can only be explained by the separation (i.e. the Doppler effect), or by a distortion of time, as when light gets out of a gravitational well (e.g., this kind of effect can be seen when light leaves Earth, the Sun, or - to a greater degree - when it leaves a neutron star). Or do you have a third explanation for this discrepancy in timing?
