Yes, researchers are actively searching for dark matter through various experiments and observations in order to better understand its properties and role in the universe.
After consuming all nearby matter, black holes continue to exist in space but may not be actively consuming more matter.
There are different forms of ghost hunting, some of which are scientific. For example, I used to do ghost hunting (although now I just research ghosts) for scientific evidence. Or, science is how you investigate a subject matter, not the subject matter itself. Anything can be a science if you approach it scientifically. None of the current TV shows about ghost hunting, however, appear to be very scientific with their approach.
Not all black holes have accretion disks. The presence of an accretion disk depends on the black hole's surroundings and whether it is actively consuming nearby matter.
Astronomers discover black holes in the universe by observing the effects they have on nearby objects, such as stars and gas. They use telescopes to detect X-rays and other forms of radiation emitted by black holes, as well as studying the gravitational influence they have on surrounding matter.
Albert Einstein developed the theory of relativity, which led to the famous equation E=mc^2 that describes the relationship between matter and energy. Through mathematical analysis and thought experiments, Einstein posited that energy and matter are interchangeable and can be converted into one another, revolutionizing our understanding of the universe.
Matter naturally exist, no need to be discovered.

Maxwell's studies helped Wilhelm Roentgen discover energy waves that were capable of penetrating solid matter
When they discover new intelligence on the matter.
You need a hunting license no matter what. Unless it is a non game species.
After consuming all nearby matter, black holes continue to exist in space but may not be actively consuming more matter.
as of 1995, scientist have identified five states of matter. They may discover one more by the time you get old

It does not matter how old you are, you just have to have a hunting license.
Animals, hunting, several walls have handprints on them.
He discovered that oxygen is present in the burning of matter.
