Is there a difference between "dark matter" and "antimatter" or does it really matter!?

Question

A black hole may be made of "dark matter" or "antimatter!?"

Answer 1

Dark matter is matter, not directly observed and of unknown composition, that does not emit or reflect enough electromagnetic radiation to be detected directly, but whose presence can be inferred from gravitational effects on visible matter.
Antimatter extends the concept of the antiparticle to matter, wherein if a particle and its antiparticle come into contact with each other, the two annihilate or cause the equivalent to a nuclear explosion, similar to nuclear fission —that is, they may both be converted into other particles with equal energy in accordance with Einstein's equation E = mc2.

Answer 2

Right on track Beep but fission is inefficient, and even fusion doesn't compare to total annihilation. In a matter-antimatter catastrophe the energy produced is equal to the sum of both masses involved, as you noted pursuant to E=mc^2 where c is the speed of light, or 3 x 10^8 m/s.
This is an enormous amount of energy.

Answer 3

Of course there is regardless of the color (dark matter) the key here is anti matter but the lesson here is the basis of every single thing in our universe contradiction this is what makes life and yes death so it does matter because at the end of the day that is all that matters

Answer 4

As a matter of fact they are both theoretical entities and may or may not be able to exist.
The black hole is a theoretical entity that can't exist!

Answer 5

It really does matter

Anti matter is a opposite to matter we observe. they are complimentary.
Whereas dark matter is invisible 'matter' whose presence can be felt just by the other effects and behaviour like normal matter

Answer 6

It doesn't matter. Neither really exist only as outlandish theories.

Answer 7

big difference
