What visual effect results from floating within the core of a dark nebula?

Answer

Profound darkness punctuated only by the occasional dim, cold star.

Dark nebulae are defined by their extreme opacity, caused by the thickest accumulations of obscuring dust particles blocking virtually all background illumination. If an observer were situated within the heart of one of these structures, the visual experience would be dominated by near-total blackness. While the region is rich in material destined for future star formation, the density of the obscuring dust is so great that it prevents light from distant sources, including background starlight, from penetrating. The only things potentially visible would be very nearby, intrinsically faint or cold stars whose light manages to penetrate the barrier, leading to an appearance resembling a true void.
