“black holes aren't as black as they are painted. They are not the eternal prisons they were once thought…things can get out of a black hole both on the outside and possibly to another universe. So if you feel you are in a black hole, don’t give up – there’s a way out.”
Blackholes made from massive stars which have gone supernova with such dense gravitational mass that light cannot escape from them, hence the reason they are invisible to our spectrum of vision.
A stellar-mass black hole, with a mass of tens of times the mass of the Sun, can likely form in seconds, after the collapse of a massive star. These relatively small black holes can also be made through the merger of two dense stellar neutron stars. A neutron star can also merge with a black hole to make a bigger black hole, or two black holes can collide. Mergers like these also make black holes quickly, and produce ripples in space-time called gravitational waves.
The giant black holes found at the centres of galaxies — the "supermassive" black holes, which can weigh millions or billions of times the mass of the Sun. It can take less than a billion years for one to reach a very large size, but it is unknown how long it takes them to form, generally.
Dark matter comprises 80% of the universe but is still not fully understood if it is a particle which we have not been able to see. Scientists know of its existence by the interaction of other entities and the gravitational forces of the dark matter affecting them.
Blackholes eviscerate or spaghettify stars which become trapped in their gravitational hold but ultimately stars make them so to me it seems they act as limitation valve in the more reactive entities of the universe.
Ghost particles called neutrinos are a by-product of a star being devoured by a blackhole and constantly bombard us but are so small in mass that we cannot detect them. However they maybe the reason that any matter existed at all after the big bang as according to physics the matter should have been cancelled out by anti-matter.
Stephen Hawking theorised that smaller primordial black holes not made from stars exist which eventually extinguish due to his theory of radiation emission. The quotation above was made in one of his final addresses before he passed away and was referring to people who may be affected by depression.
Blackholes are mentioned as the catalyst for destruction and propulsion of human knowledge in sci fi novels Hyperion , Ileum / Olympos by Dan Simmons. The latter two books tell of a man made black hole destroy Paris and is recounted in poems by the main character. Dan Simmons is a writer that uses cross genres ranging from sci-fi, fantasy and horror with inspiration from classical literature such as The Canterbury Tales by Chaucer and Ancient Greece. These books also touch on themes of post human era's beyond technological singularity ie where technology advances beyond human comprehension such as AI evolving into superintelligence.
Several episodes in Doctor Who feature black holes or situations relating to them, notably "The Three Doctors", "The Horns of Nimon", "The Impossible Planet", "The Satan Pit", "World Enough and Time" and "The Doctor Falls". Furthermore, the Eye of Harmony is a black hole used by the Time Lords as a power source for their "TARDIS" time machines. As established in "The Deadly Assassin" it is kept beneath the Panopticon, the hall of government in their Citadel, and in the original series links the TARDISes together. In the new series episode "Journey to the Centre of the TARDIS" there is a power room where the collapsing star that created the black hole is shown. As you can see I am a bit a fan of the Doctor.
In the Stargate SG-1 episode "A Matter of Time", a wormhole is opened to a planet near the event horizon of a black hole, causing the gravitational and time dilation effects of the black hole to threaten Earth. Black holes play a major role in Stargate SG-1, and appear in many episodes.
The image on the cover of Voloc's Reign shows the event horizon of a blackhole with the eyes of a malevolent being peering out. So what is Voloc? A demon, a force within a black hole, dark matter animated to life in the clay world of Arglethium? The wolf predator in some forms, a demon to others, the impenetrable shadow and gaoler of Baachelaus. First creature of the void made in the wars of creation which pervades the hearts and minds of ones called the clayborn but also dwells in the tombs of dead stars. I wont use the word evil, as it limits the understanding of why things which cause destruction exist, instil fear and harm, whether it is due to deliberate intention or from natural forces which impose limitation on the world and universe in general.
Voloc is given its time in the sun in the LOC series and like the iron dense heart of a dead star, Voloc is drawn to the cornucopia of matter within Arglethium.
Demons and their legions await ! Stay tuned.
