Getting the actual theory being referred to wrong is more than a typo. You're right, John. It was a really stupid screwup from not proofreading the damn thing. Thanks. Hey, want to call a truce? oc |

A blackhole has to be a vortex in the fabric of space. It is impossible
for me to visualize it any other way. It would create to many problems seeing it with the features of a neutron star. Gravity has squeezed a blackhole out of the macro universe. It has no volume,and that has to tell you something. A singularity and a blackhole are given two different names,but in reality one name is all that is needed,and that would be "singularity" Bert |

From OG:
I don't know why you've mentioned Einstein here. I thought you rejected the idea of curving space. Are you saying he is right after all? Also note that Einstein is talking about the velocity of light, not it's speed. Yeah, the velocity changes, but that's inevitable if the direction changes. You are right. It was a very, VERY stupid screwup and inexcusable. It stemmed from failure to note the difference between 'speed' and 'velocity', and usage of 'SR" when GR was intended. Utterly, utterly stupid and sloppy, and a valuable lesson to PROOFREAD before hitting 'Send'. And thank you, Zinni. Re. the cosmological density gradient, you wrote, I can see why the light would lose speed, but I can't see why this would cause a loss of amplitude, rather than wavelength. I know you don't like analogies, but think about a comparison with air. Pressure/density at sea level is higher than at say, 40,000 feet. Sound originating in a region of high density/pressure is naturally going to lose speed and amplitude as it propagates into a region of lower density/pressure. Note that the frequency remains unchanged. Light from the most distant 1a SN remains unchanged in redshift, but 'dimmer than it should be'. This of course has been interpreted as further evidence of ever-accelerating expansion of the universe, since it makes no allowance for a cosmological density gradient. You equate the pressure and the density - are these in a linear relationship? Yes. In the context under discussion, the term should actually be 'pressure/density' or 'density/pressure'. I thought concentrated mass caused the pressure/density to reduce - you know like it does near the Sun and the Earth. Please explain the difference. I thought this point had been made crystal clear, having delineated it several times already. Again, the expansion of space from the BB is the inverse of gravitation, constituting a dipole relationship between outflow and inflow. Inflow into gravitating masses is the reverse of outflow from the BB event. H.C.Warren says the same thing in his thesis, where he writes, "If gravitational processes are seen as the converse of Big Bang processes, then in combination nature reveals a dipole character." Tell you what, OG. I have tried to indulge your many points of query, while you have repeatedly avoided addressing those four 'Mainline Issues' i keep asking you to address. As stated before, all this 'details' stuff amounts to nothing unless and until those 4 issues are addressed. Again, they a 1. Why is the speed of EM (and supposedly GW) radiation a fixed value? If there is no medium, why is c not widely variant or even infinite? "Permittivity of space" does not answer anything. What is "space"? 2. Why is c as high as it is? A propagation speed this high demands a carrier medium of **enormously high** density/pressure. If there is no medium, why is c as high as it is? "Permittivity/permeability of space" does not answer anything. What is "space"? 3. Again, and this is the *pivotal* point, there is NO PERCEPTIBLE UPPER LIMIT TO THE AMPLITUDE OF EM RADIATION (or GW radiation supposedly). This demands a carrier medium of even greater energy-density (sub Planck 'granularity'). If there is no medium, how is this accomplished? 4. By all appearance of its behaviour, gravity is a pressure-driven, accelerating flow into mass. It has the ability to crush massive stars down to singularities. This indicates a medium of incomprehensibly high density/hydrostatic pressure. If there is no medium, how is gravitation, and gravitation of this magnitude, accomplished? One thing's for sure- it isn't accomplished by "metrics", geodesics, and equations which are _descriptions_ of the process. What is that process? Put the whole thing in this context, OG. You are the learned one, the credentialed, tenured professor. And i am the stoont, er, student come to you for knowledge and enlightenment about your worldview. In my naivete i have presented these 4 issues and need clarification on how they are explained under your worldview, which is rooted in the no-medium premise. If you would like, you could do it in a new thread as this one is getting quite lengthly. Your humble understudy, oc |

Sound originating in a region of high density/pressure is naturally going to lose speed and amplitude as it propagates into a region of lower density/pressure. In fact, the speed of sound is more or less given by v_Sound = K * SQRT( Pressure/Density) , so assuming that pressure and density are proportional (as you said below), then the speed of sound is independent of pressure. However, to preserve energy the 'amplitude' of the pressure wave increases as the sound moves into lower density air. Just as well this is only an analogy ! Note that the frequency remains unchanged. Light from the most distant 1a SN remains unchanged in redshift, but 'dimmer than it should be'. This of course has been interpreted as further evidence of ever-accelerating expansion of the universe, since it makes no allowance for a cosmological density gradient. |

I thought this point had been made crystal clear, having delineated it several times already. No I think you have written what you think happens, but not explained WHY it works this way.

Inflow into gravitating masses is the reverse of outflow from the BB event. H.C.Warren says the same thing in his thesis, where he writes, "If gravitational processes are seen as the converse of Big Bang processes, then in combination nature reveals a dipole character." I love this - in semantic terms this says If assertion THEN converse Brilliant - can I do my own? If this theory is right then the rightness of this theory is self evident Ah, it's not as good as Warren's. ;-( |
