Just read a book by a Japanese physicist at ?? university in New York - unfortunately his name escapes me, must be getting old. He went into great detail about dark matter and so forth, easy to read -especially for old guys who last took physics 40 years ago- clear explanations, and lots of material about future discoveries.

Then again, we don't know of anything that can except for things that we don't know exist - e.g. undiscovered fundamental particles, interactions with a parallel universe (yes, some people have theorized this, I saw a seminar about Brane Theory that touched on the subject).
