I doubt if you could get such a wave length simply as the goal post is always on the move☺...I think when a photos energy is that diminished it could not go anywhere and would accumulate with others like it to form dark matter...and it would take a lot of them because they are massless.

And why not? Maybe there are lots of photons that have energies that are not zero, yet with wavelengths too long to be detected.
Come to think on it, A photon with a wavelength equivalent to the size of the observable universe would have the highest probability of detection wherever where the observer happens to be, since every observer is at the centre of their own observable universe. To exist within the observable universe, yet have a wavelength of equivalent size *to the observable universe, places the probability wave at the centre of that same observable universe.
But I think I'm correct in saying that Heisenberg's conjugate variables would mean that a precise knowledge of the location of such a particle would therefore also mean that we couldn't *also know the energy of such a photon.
I suppose - and I'm thinking very up in the air now - that since it is not possible to have a photon with greater wavelength than the universe itself, that one could consider the wavelength of such a photon to be a 'base frequency' of the universe. Higher frequency photons would constructively or destructively interfere with the 'primordial' photon creating interference diffraction patterns (this would not be the case if the lower extent of wavelength was infinite and it were possible to have a photon with a wavelength longer than the observable universe). Perhaps detection of interference patterns would tell us if there is much energy at these lower wavelengths?
Interesting to ponder, but I'm probably just talking a load of old Bahtinov, as I don't have any kind of qualification in the area. Some long-suffering physics professor will probably chime in and slap me around the head for thinking such things, and fair enough too. :-)
