I’ve done a bit of research about this, but I can’t find any definite answers. Do scientists have any facts on dark matter, and do they know exactly what it is? Any potentially plausible theories?
IANAA, but I was under the impression that dark matter is any typical matter that is not self-luminant (such as stars, glowing gases, and what have you). Therefore, very hard to identify since there is no direct way of detecting it. My WAG is that it is comprised of mostly gases, particles, dust, and even space debris like asteroids, comets, and maybe even planets that have no external light source to reveal them… I’m sure someone more capable will be along shortly to give you the real scoop… please forgive me if I’ve misled.
