Before, TreBert said nothing could slow down light.
Y'all might want to read up on the 'River' model of black holes, which
is actually being circulated in mainstream venues. It's based on the old Painleve`-Gullstrand metric, which describes gravity as the accelerating flow of space into mass, but now updated to include black holes. http://search.yahoo.com/search;_ylt=...&cop=&ei=UTF-8 However, the authors are careful to clarify that the model is 'heuristic' or allegorical and not meant to imply that a *literal* medium is literally flowing/accelerating. They're constrained to operate under the 'no medium' doctrine, and so have to portray an allegorical river as accelerating relative a fixed background rather than admit the obvious and self-evident : the "background space" IS literally the 'River' that is literally flowing/accelerating into the BH. There is no other explanation for the mechanism that powers the most energetic gravitational phenomena in nature, like super/ hypernovae and quasars. Either gravity *is* exactly what it appears to be and behaves as, or it's angels, imps and Sky Pixies all the way down. :-) |

Uh.. the intended, original paper didn't show up in that batch. So here it is - http://arxiv.org/PS_cache/gr-qc/pdf/0411/0411060v2.pdf ...with the caveat that it's portraying an allegorical rather than literal flow of space, requiring a rather convoluted mathematical/ geometrical representation of how the allegorical flow "spirals and twists" relative to the flat background. A much simpler, math-less depiction would just let the 'background' itself do the spiraling/ twisting flow into the BH. |

Light climbing out of an apparent black hole has a finite red...

BG My point is gravity lengthens photon waves and great heat can make them short. So around a black hole we see an accretion disc,and that disc I relate to photons leaving the fusion core of a star is gamma photons,but again by the time they break through the stars surface we see these photons as white light. When looking at the hub of spiral galaxies it looks very bright white. That is what I tried to bring out in my post. White light is all photons waves mixed. I see it clearly as two forces Gravity and EM. Gravity is the stronger force,but distance can make them equal(natures balancing act) or weaker or stronger as the case may be Go figure TreBert I do believe that gravity has a pulling affect on behalf of stretching those photons. However, the human eye sees perhaps 0.0001% of the photon spectrum. Even if we could see 0.1% with the aid of advanced optical technology that included UV and IR, we'd be considered legally blind by the cosmic way of such matters. ~ Brad Guth Brad_Guth Brad.Guth BradGuth BG / “Guth Usenet” http://www.alaskapublishing.com http://www.guarddogbooks.com |

Jeff I must post this once a week Photons can not go faster or slower than 186,242 mps Photons do not bounce. Photons do not age Time does not exist for photons. If a person was in a space ship going at c he could be every where in the universe instantaneously. Photons can only travel in pairs like matter particles. If electron could go at c only one electron would be needed to service the universe(Feynman and Wheeler fooled with that idea) Photons are both a wave and a particle. Gamma photons more like a particle,and radio photons more like a wave. Photons can be made to do many forms of work. Being very polite by opening doors for humankind. I like that TreBert Ps not all of this post comes from my mind alone,some of it also comes from other great thinkers Question; are stars (like our sun) visually dark inside? You'd think the stellar interior (say whatever’s within 0.99r) would become mostly of UV or higher frequency photons (certainly hotter than the outer photosphere), so visually dark seems likely. Perhaps the solar visual spectrum wouldn't happen until 1.01r or greater, and solar IR a little beyond that. Solar 1.01r = 6.94e5 km + 6.94e3 km = 6.947e5 km Of what we visually detect as the outer photosphere may in fact not be the solar surface. A narrow bandpass of EUV(extreme UV) might suggest the solar surface radius as being less than the visual photosphere radius. In TRACE observation format, our sun seems to have a semisolid though extremely active surface. http://www.cuodan.net/gallery/v/misc...ce_uv.jpg.html http://trace.lmsal.com/POD/TRACEpodoverview.html (major download) ~ Brad Guth Brad_Guth Brad.Guth BradGuth BG / “Guth Usenet” http://www.alaskapublishing.com http://www.guarddogbooks.com |

Nothing in the Sun is solid, BradBoi! lmfjao!

Besides photons getting away from a conventional main sequence star being easier said than accomplished, photons should have a really tough time getting through all of that cosmic ISM of black diamond, as perhaps representing dark matter. For all we know, a black hole could be a solid carbon black dwarf, as a solid sphere of black diamond (possibly with a thorium core for good measure). ~ BG |

Bg Inside the Sun just before the core is the Radiative Zone It has
photons in the wave length of light Its this zone that photons bounce between the layer particles so many times that each photon takes 200,000 years to reach the convective zone. So it is written TreBert |

Before, treBert said nothing could slow down light.(light 1speed)
BG Never said photons slow down(they can not) I said visible light
photons become visible once leaving the sun surface. Read it right,so you can quote it right, Do not be a Cactus Saul TreBert |
