    Ummm… Only thing we’re sure of is that those gravitational effects exist. Dark matter and dark energy are theorized to explain the real gravitational effects that we don’t understand. We don’t “know of their existence,” there are other theories to explain the gravitational effects.

    Fyi, there’s a lot of woo woo (edit: apparently racist term) crap out there that tries to make you believe that somehow the photons can feel that a human is watching them and they choose to behave differently as a result. This is not true. It just means that when you use a detector or some sort of probe that physically interacts with the photons they change their behavior. It’s not magic.
