Sound wave, light wave, gravity wave, and then Dark Matter wave?

[alpha2cen]

We know many waves, i.e., matter wave (sound wave, earthquake wave, water wave), electromagnetic wave(light wave), gravity wave. And, we have tried to find Dark Matter. If so, are there other waves we have not seen or imagined yet? At the present we can not detect them easily like Dark Matter.

We try to explain after Big Bang event by using matter, Dark Matter and Dark Energy concepts.

But we detect only CMB. Other undiscovered phenomena would exist. Neutrino which was created by Big Bang , gravity wave, other small or big size particles and other unknown waves --- I suppose at that high temperature state other forms of wave would be exist .

In the other case we can consider Black Hole. If nothing escape form it, there would be very very huge Black Hole exists in some region of the Universe. But we have not seen so huge Black Hole yet. I suppose some waves which we can not detect could be released from that Black Hole.
