Q&A: Dark Matter

Q:
I am fascinated by the paradox of dark matter. The last few years has witnessed a rapidly expanding amount of black hole and super-massive black hole "verification". My question is, could this acceleration eventually solve the "missing matter" equation? How far would we have to go?

A:
It appears that you are talking about both dark energy and dark matter, where the former is thought to cause the expansion of the Universe to accelerate and the latter is thought to make up about 80% of the matter in the Universe. The properties of these two components are quite different: the distribution in space of dark matter is clumpy but dark energy appears to be smoothly distributed. It is possible that these two components are related, but little is known about either of them. The best guess right now is that they're unrelated and that dark energy comes from the energy of empty space and dark matter is made up of some unknown particle.
