A black hole doesn't cause anything. It is a gravity trap - a place where gravity has gotten so strong nothing can escape (excluding Hawking radiation at the event horizon.) What happens is a star (or stars) is (are) so heavy after burning much of their hydrogen into helium that the star(s) start to collapse in on itself. If there is a certain amount of mass at a certain distance (critical mass) then even light can't escape the gravitational pull and now it is a black hole. Because energy can't just disappear and Hawking radiation exists, after enough time a black hole can expend itself - burned so much matter to energy that it 'dies' - that is it expends the last of it's energy in a humongous burst of radiation - an explosion of light if you will and all that's left are those echoes of it's death.
No, the sun is not dark matter. Dark matter is a mysterious form of matter that does not emit, absorb, or reflect light. The sun, on the other hand, is a star that emits light and heat due to nuclear reactions happening at its core.
A dark matter microscope is used to indirectly detect and study dark matter by analyzing the impact it has on the distribution of visible matter in space. By observing the gravitational effects of dark matter on visible matter, scientists can infer the presence and properties of dark matter particles.
No, dark matter is entirely different from antimatter. For one, we know a lot about antimatter and have been able to do experiments with it and actually utilize it in some nuclear reactions. Dark matter is a theory to help understand why the universe does not behaive the way we believed it should. Galaxies are showing that they do not have enough mass to have the gravitational effects that they do, so there must be matter somewhere, this is labeled as dark matter.
It would be quite difficult to put a price on dark matter as of now, because we don't even know what the stuff IS.
When the total amount of mass in a galaxy is computed, and the total amount of gravity is calculated there is a discrepancy. There appears to be more matter in the galaxy than what can be observed. Dark matter was theorized as being matter that exists but does not interact with electromagnetic radiation. Because of this, it cannot be seen. That is why it is called dark matter.
Dark matter is an unknowm form of matter.

The most common type of energy/mass in the Universe is in the form of dark energy, followed by dark matter. Only about 4% of the Universe is in the form of "normal" (baryonic) matter. If it is specifically to this matter you refer: the most common state of matter is plasma, found in stars.
Yes, that's quite true! For more information, read sources such as Wikipedia on "dark matter" and "dark energy". Current estimates are that something around 68% of the mass-energy in the Universe is in the form of dark energy; 27% is in the form of dark matter; and about 5% matter of known types. Nobody really knows much about "dark energy" or "dark matter" - only that they exist.
Dark matter is a mysterious substance that does not interact with regular matter, so it is unlikely you would be able to walk through a wall made of dark matter. Our current understanding of dark matter is that it exists in a halo around galaxies and does not clump together like regular matter to form solid structures like walls.

Dark matter is everywhere, there really is no place that has the most dark matter.

Dark matter does not move faster than the speed of light. It interacts gravitationally with other matter, affecting how galaxies rotate and clusters form, but it does not move on its own at superluminal speeds.
