You detect dark matter through its effect on gravity. Galaxies spin at a rate not possible without extea mass, so we say there's "dark matter" there causing that

dark matter has a gravita and dark energy, simply said just has a force on the matter around it

only way to detect it, (and this is a guess people are pursuing) would probably be interaction via the weak force, or mediated by something we don't know

If it can't be percieved, then we should be able to "see" it by knowing where what we can see isnt', like a missile

And dark energy is what we say is causing the acceleration of the expansion of the universe. It has an expansive effect on spacetime, gravity has a contractive one

if matter and anti-matter collides, they anihilate each other and release energy. dark matter just passes through

You detect it by measuring its gravitational effect. It doesn't interact with light so we cannot observe it. We think is there because we observe gravitational effects that can't be explained without

Antimatter is matter with antiprotons instead of protons. Charges are reversed, and annihilates matter when it contacts it.

You know, there is a way to solve the delay, play the stream at x1.25 rate until it catches up

antimatter can be viewed as normal matter going backwards in time (for the purpose of calculations this is mostly adequate)
