[Fwd: Top Secret Earth Station Message-Five Star-*****]
Is the speed of light increasing as space gets less dense, or is it slowing down? Does the speed of sound in air increase or decrease with diminishing density/pressure? Pretty much a no brainer. This sounds interesting. Why is it interesting? Space is a 'void', remember? |

The speed of sound is independent of pressure at constant temperature. http://en.wikipedia.org/wiki/Speed_of_sound So are you saying there is NO dependence between the speed of light and the density of space? |

So are you saying there is NO
dependence between the speed of light and the density of space? AAArrrrrgh. And double AAAArrgh. In the analogy with the speed of sound-- what happens to sound speed in air with diminishing density, as at higher altitude or in a hypobaric chamber? Obviously sound speed decreases. Likewise, lightspeed decreases with diminishing spatial pressure _as seen from an 'outside' referance frame_ . Yet from the 'inside' frame, locally, lightspeed is constant per SR and the Lorentz invariance is never violated _locally_ . 'Local' in this context refers to our neighborhood in the supercluster several billion LY across, across which there is negligible density gradient. Locally, space can be treated _as if_ it were a void, and relativity 'works' acceptably well. But not at deep cosmological distances where the density gradient begins severely steepening. Transpose yourself mentally 'outside' for a moment, and you'll see the corresponding change in lightspeed across the density gradient. From 'inside', we see the effect as excessive dimming of the most ancient light. However this is all malarky since in your worldview there is 'no medium' and space is functionally a void. So there is no basis for discourse on it. |

Not obviously at all - any reduction in speed is due to temperature related effects. Did you read the link I gave? 2nd paragraph "The humidity has very little effect on the speed of sound, while the static sound pressure (air pressure) has none." 4th paragraph "In fact, assuming a perfect gas the speed of sound depends on temperature only, not on the pressure" |

From Ray V:
Swap the two points for two distant galaxies or clusters of galaxies with localisd forces ignored. Again with these two points existing in nothing how can this movement be explained. Well, the 'Something that is yet Nothing' corresponds to the missing 'dough' in the raisin bread analogy. To the Void-Spacers, there is no dough, nay cannot be. To suggest that the dough is the Primary Reality of existance with matter tagged on as a superfluous 'dustbunny' is apostacy against the Faith. The Void-Space Paradigm(VSP) is a latter day doctrine equivalent to the geocentrism of Ptolemy.. and its adherants just as fiercely zealous as at the inquisition of Galileo. The dough, the 'Something that is yet Nothing', by dint of its expansion, exists in a state of _flow_ . Flowing space.. Flowing outward, expanding from the initial eruption of the BB, carrying matter along for the ride. If it's expanding, it hasta flow. Doh. The 'dough', the spatial medium, is a perfect fluid or 'hyperfluid' as evidenced by our Newtonian laws of inertia and momentum (i.e., objects in motion translate frictionlessly thru the medium, resisting acceleration. But once accelerated (or decelerated), again translate frictionlessly at the new velocity.) The flowing-space model of gravity posits matter as a spatial sink, or vent, with the medium flowing _into_ matter, into the lowest-pressure zone at the core of every atomic nucleus (which also happens to be the unification of gravity and the strong nuclear force). This implies that the spatial medium exists in a state of extreme hyperpressurization that exceeds the degeneracy pressure of the atomic nucleus, as in a black hole collapse. And we are Pressure Dwellers, having no sensory awareness of the extreme hydrostatic pressure of the 'ocean' in which we dwell. And because it's a perfect, frictionless fluid ('hyperfluid') we mis-interpret it as a void. Further evidence of its extreme hydrostatic pressure and _sub-Planck energy density_ is the high value of light's propagation speed. Friend OG has stated that the FS model of gravity fails. But as far as i can tell, it fails only to explain the 'roach motel' issue of "where does the stuff go once ingested thru the atomic nucleus?" By the same criterion, the BigBang model fails because it cannot explain "where does the stuff come from?" The FS model recognizes gravitation and the BB process as a balanced dipole, sharing a common 'ground state'. We here on 'this side' are privy to see only one side of the dipole. Whatever strange nonlocal, non-plural realm exists on the 'other side', we are not yet privy to. Yet by all evidence, logically it's one and the same "place". Of course all this is total baloney to the Void-Space mainstream. Yet they have no aversion to positing even stranger, occultish-sounding stuff like 'curled up dimensions', dark matter/energy, 'quintessence' etc. oc |

Nope sorry, In that case there is no increase in separation and nothing to explain Yes there is, the separation is observed and can be measured, the motion of the two points can be accounted for, except the separation, the only explanation on offer is that the void, the nothing, is expanding thus increasing the distance between the two points. This explanation smacks of desperation. A void, a nothing expanding??, oh please. I would still like to see an explanation of how this nothing is expanding. Maybe the nothing is not expanding but that new nothing is being created in the already existing nothing thus creating even more nothing that goes on to create even more nothing and so on and so on ;-) Merry Christmas |
