Light is redshifted and the greater the z, the further the spectral shift is to the left. Is there a point at which low-frequency EM (radio/micro waves) shifts below the spectra and disappear?
The real question - Is there a z, and thus an implied distance, at which the highest energy electromagnetic emissions - Gamma and x-rays - would shift to this vanishingly low range?
If so, then that would make objects of a certain distance invisible regardless of the age of the universe, wouldn't it?
