How can, in a dying star, the blasted matter is pulled inwards to form a black hole?

Nuclear fusion is no longer taking place, so the star has no way to stop itself from collapsing under its own gravity.<br /><br />Nuclear fusion acts as a stabilizer for a star against its own crush of gravity. The balance of outward pressure from nuclear energy and the crush of inward gravitational pull is called hydrostatic equilibrium.<br /><br />Keep in mind too that a black hole is not always formed after the death of the star. Sometimes you get a neutron star or white dwarf. <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

Degenaration of matter is first step to black hole.One should understand degeneration very well before discussing.

Degeneration of matter is essential to understand white dwarf etc.
