The safe answer to "is this dark matter" requires it to meet a couple conditions; it needs to have mass or interact gravitationally; and it would need to not interact electromagnetically - in other words, not be visible (hence the name, 'dark'). Scientists aren't certain yet about the identity of dark matter, largely because of the difficulty in observation, but some particles from our Standard Model may be good candidates.
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.
