There is no consensus on what dark matter or dark energy is so we cannot tell at this time.

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

There's no such thing as a "dark matter microscope." The whole point of dark matter is that it doesn't interact with electromagnetic radiation... if it did, it wouldn't be dark matter.

Dark matter is an unknowm form of matter.

Dark matter and dark energy have NOT been detected yet, so any ideas about detecting dark energy and dark matter, whether it be directly or indirectly, is speculation for now.
