Not much is currently known about dark matter. We know that there is some unknown substance that makes up 80-90% of a typical galaxy or galaxy cluster - and we know so by its gravitation - for example, by observing the rotation of a galaxy, or by gravitational lensing.
The idea is to find out how the Universe works.
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.
