Quraan On Pulsars & Black Holes

Pulsars & Black Holes

When large mass concentrates into very small volume it makes a black hole.

Pulsars are rotating neutron stars. Most neutron stars discovered today are in the form of radio pulsars. They are called radio pulsars because they emit radio waves. We can simply connect a radio telescope to a loud speaker and hear a pulsar. Pulsars sound like someone persistently knocking. Click here and listen to a slow knocking pulsar. Click here and listen to a fast knocking pulsar. So in short, we can hear a pulsar knock.

The Quran describes a star by "The one who knocks":

[Quran 86.1-3] And the heaven and the "Knocker" (Tarek in Arabic طارق) How could you know about the "Knocker"? The piercing star (Thakeb in Arabic).

The Arabic word "Thukb" means a hole; "Thakeb" means the one who makes the hole. The Quran is describing a knocking star that makes a hole.

Pulsars are rotating neutron stars. As more matter falls into a neutron star its mass increases and as its mass increases its gravity increases. But gravity is actually curvature of spacetime. A neutron star distorts spacetime. As more matter falls into a neutron star distortion increases. A point will be reached where distortion would have grown so much that it makes a hole in spacetime.
