This is still a work in progress. Scientists are trying to answer this question. All we know is that it provides gravitational attraction, yet it can't be seen through any means. The presence of dark matter is inferred from the movements of matters that we can see, such as stars, galaxies, etc. But dark matter does not emit or reflect any light. This is the puzzle.
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.
Dark matter is everywhere, there really is no place that has the most dark matter.
Dark matter is an unknowm form of matter.
The opposite of dark matter is visible matter.
Dark matter's strength is proportional to it's mass. This means that more dark matter in one spot is stronger then a little bit of dark matter in that same spot.

Dark matter is invisible. It doesn't interact with light.
