A common type of black hole is produced by certain dying stars. A star with a mass greater than about 20 times the mass of our Sun may produce a black hole at the end of its life.

In the normal life of a star there is a constant tug of war between gravity pulling in and pressure pushing out. Nuclear reactions in the core of the star produce enough energy and pressure to push outward. For most of a star’s life, gravity and pressure balance each other exactly, and so the star is stable. However, when a star runs out of nuclear fuel, gravity gets the upper hand and the material in the core is compressed even further. The more massive the core of the star, the greater the force of gravity that compresses the material, collapsing it under its own weight.

Ilmu pengetahuan moden, ilmu astronomi, baik yang berdasarkan pengamatan maupun berupa teori, dengan jelas menunjukkan bahawapada suatu masa seluruh alam semesta masih berupa 'gumpalan asap'(iaitu komposisi gas yang sangat rapat dan tak tembus pandang, The First Three Minutes, a Modern View of the Origin of the Universe , Weinberg, hal. 94-105.). Hal ini merupakan sebuah prinsip yang tak diragukan lagi menurut standard astronomi moden. Para ilmuwan sekarang dapat melihat pembentukan bintang-bintang baru dari peninggalan 'gumpalan asap' semacam itu (lihat gambar 10 dan 11)

Bintang-bintang yang berkilauan yang kita lihat di malam hari, sebagaimana seluruh alam semesta, dulunya berupa materi 'asap' semacam itu. Allah telah berfirman di dalam Al Qur'an:
