Black holes would be one of the next steps. If Astronomer Mike were to have continued on in his explanation past the theorized "quark stars" he would have soon gotten to black holes.<br /><br />Black holes occur when the mass of the star in question is enough so that the amount of gravity it has outweighs any repulsion it could possibly have on an atomic level. Thus it collapses into a point in space called a singularity. This singularity is a point in space that is so infinitely dense and infinitely small nothing can escape its gravitational pull once the object crosses what is called the event horizon of the singularity in question.<br /><br />The event horizon is simply a point of no return. If something is still on the outside edge of the event horizon it is still possible to escape the gravitational pull of the singularity. Once that something has crossed the event horizon, all hope of escaping the gravitational pull is lost.<br /><br />Hope it helped (and I hope I didnt get it wrong - haha).Anonymoushttps://www.blogger.com/profile/08655887802519987671noreply@blogger.comtag:blogger.com,1999:blog-8625613341885362314.post-36880158431827274272009-04-04T17:49:00.000-07:002009-04-04T17:49:00.000-07:00it's the eagle eye nebula.it's the eagle eye nebula.Nabeelhttps://www.blogger.com/profile/17350990439729881786noreply@blogger.comtag:blogger.com,1999:blog-8625613341885362314.post-81297283004147294432009-03-25T12:13:00.000-07:002009-03-25T12:13:00.000-07:00I really love this blog.

The laws of quantum physics state that there's only so tight that you can pack mass before all the electron orbitals are essentially touching one another with no room to pack any more in. This state - known as "electron degenerate matter" - is precisely what happens. The result is an incredibly dense, former stellar core roughly the size of the Earth made of this exotic degenerate matter, known as a "white dwarf". It no longer generates its own energy, but it is quite hot - one can think of it a bit like a dying ember from a former campfire. The electron degeneracy pressure keeps it from collapsing further.<BR/><BR/>Excuse me. This degenrate matter,incredibly dense from your above quote,"white dwardf".is likened to a dying ember that does not collapse further. Where does the role of "black holes" play in this priocess? What are black holes?Edward Yablonskyhttps://www.blogger.com/profile/10013345997672210570noreply@blogger.com
