then

the read this :)
Neutron stars are remnants of exploded stars (see: Iron). As more matter falls into a neutron star its mass increases; and as its mass increases its gravity increases. A point will be reached where gravity would have grown so much that not even light could escape, thus a black hole forms.

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; and if matter continues to fall into this pulsar a black hole will eventually form. Moslems say that this is what Allah says. The Quran describes a star by "The one who knocks" and says that it is "The one who makes a hole".

[Quran 86.1-3] And the heaven and the "Knocker" (Tarek in Arabic) 2 How could you know about the "Knocker"? 3 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.

At the center of black holes (collapsed stars) lies a ******** called the Singularity. An observer far away from a black hole sees the events near a back hole in slow motion. If he shines a beam of light into this black hole he will have to wait forever but still this beam of light will never reach the singularity. The singularity is a ******** where gravity has gone so mad that space and time become indistinguishable. From general relativity we know that this is a ******** where the structure of spacetime becomes singular (hence the name singularity). However singular (Ahad in Arabic) is one of God's 99 names. In the Quran God swears by the ********s of stars which turned out to be His own name:

[Quran 56.75-77] I swear by the ********s of stars, 76 it is a great swear if you knew, 77 it is a noble Quran...

Here God swears not by the stars themselves but rather by their ********s (mawakeh in Arabic). Today we know that these ********s are singular, that is, they carry God's own name: "Ahad".
Moslems ask how could an illiterate man who lived 1400 years ago have figured out Pulsars, Black Holes and Singularity?

[Quran 26.2-6] These are the verses of a clarifying Book. 3 You might be frustrated that they don't believe; 4 If We wish, We hand down from the heaven a sign (proof); their necks to it remain subdued. 5 And every new revelation they were given from The Most Gracious (Allah) they dismissed. 6 They disbelieved (the Quran), so they will receive the news of what they have been mocking.
