A black hole is a star that implodes upon itself puncturing a hole in the fabric of space-time. It is the darkest thing in the universe as not even light can exit its gravity once it enters its event horizon, the point of no return.
The irony is that the darkest object in the universe emits the brightest light in the observable universe by means of a quasar.
At the center of every galaxy is a super massive black hole. quasars typically occur when two galaxies collide in a cosmic collision causing each galaxies stars and planets to fall into the black hole.
The radiation the outcome of this event causes is brighter than the accumulated light of 100 billion stars. The light from a quasar is a piercing light that appears to emit perpendicular to the accretion disk of the black hole (see image below).
Sura 86 of the Quran is entitled Al-Taareq. Rashad translated this word as The Bright Star.
The word Taareq comes from the root: ط ر ق. This root in the Quran is used to mean a way, path, behavior, or conduct.
46:30 They said, “O our people, we have heard a book that was revealed after Moses, and confirms the previous scriptures. It guides to the truth; to the right (طَرِيقٍ) path.
But the root of the word comes from a different source. It means two rocks smashing into each other. The history behind this root is that in the past Bedouins would knock two stones together outside people’s homes as a form of a knock to let the inhabitants know they were outside. They did this because there wasn’t a hard surface like a door to knock on. That is why all the other meanings of this word revolve around this action e.g. knock, visitor, to beat something etc.
