Dale Trynor wrote: [snip] light back to us that is claimed to have also taken 13.7 billion years for the trip = light and mass travelling about the universe for 27.4 by then, when it is only 13.7 to begin with!! You might want to review how a theory I have been promoting that gives some interesting predictions that are related to this, providing you haven't already done so. After the parts that look at how time gravitational dilation can be shown to expand space you can then look at how it examines how a coaleasing neutron star gives an inflation like appearance for any inside observers. You will note how it predicts that while the original diameters have gone from a few km diameter to light years across instantly from the prospective of each individual neutron they will still only be able to gage the size of their universe depending on how long light has had to travel. In one light second they will only observe whatever parts of their universe that light can travel in that one second and this would not change the fact that there really is light years of distance still hidden. This gives the prospective of having started from that single point even while in some ways this is only an illusion equally shared by every other point particle. So what do those beings see? Not us, as they are more light years away than the earth's age, and certainly not behind us (in their view), as we are at the 13.7 limit of their view. And what if they look outward? Are they gazing into an inky abyss? Now aren't we just so privileged to live at the center of it all? This idea of a center is very peculiar in this special theory because of how it also postulates the existence of white holes. After you review the site and have time to think about it you will have seen how and why it predicts that our universe is a black hole within another universe. The thing about black holes is they draw matter etc into them and if you were inside of a larger space within one you would see what looks like white holes pulling in matter from the older outer universe into ours. Attempts to model these white holes as they would first appear based on how a traveler would observe one while entering our universe from the outside, tends to suggest the possibility that they might appear to curve into our universe and may even appear in different locations while in actuality being the one surface. They might in some reverse sort of way be considered as the center of our universes as easily as its outside. More studies needed. Sorry about the site neglect this hobby dose not pay. http://dalet.9cy.com/ (And isn't 'The Big Bang' such an imaginitive load of rubbish??) I would like to hear what your opinions might be on this theory after you give it some thought. Sorry Dale, You are obviously a 'thinker' rather than a 'swallower', but I doubt we'll agree anytime soon. Dale Trynor wrote: I have to admit that this hypothesis on white holes is a bit speculative even for me, especially the idea that they might appear in different locations and of a rather small comparative volume relitive to the universe its must now apear inside of, while in some ways is still actuality the one single huge surface. Note that time in this theory also changes volume, so it a bit confusing about what size really is here. While I don't believe the generally accepted ideas about the big bang its still not really that much worse than the present idea that if you had a telescope powerful enough to observe the early universe that one would might be able to observe a smaller universe. Still it stretches my mind to imagine how one could measure a smaller circumference for a universe the closer you look towards the big bang even if it is just just shortly after creation. I believe I read somewhere that this could in principle work by distorting the paths in such a way as to allow that sort of otherwise contradictory observation. Its however worth pointing out how one might get similar predictions for the way one might observe a much smaller surface areas relative to our universe for white holes in this alternative theory. I don't accept the concept of 'negative' energy (push and pull are both positive), The idea of them being repulsive might in some ways be argued as an illusion, remember that while beneath such a horizon, objects appearing to be repelled are really just being pulled inwards. Might be a bit like saying objects are being gravitationally repelled from the sky. In one of the gadenkens where I examine how such things as worm holes would work I examine how an astronaut in a space craft between two black holes would observe what appears like a repulsive gravity at the center of his craft. Having a craft that could do this in our normal space would not only produce the same effect for our astronaut observer but result in a craft that displays faster time relative to us. This is still not that different from observing faster time on a satellite outside of our gravity well. Negative energy appears to be rather essential to explain how such things as the quantum vacuum and or ZPE dose not vaporize us all. If it were all positive energy it would indeed be fantastic. Note that the theory I promote leads to the idea that gravity is in part due to the differences in concentration of this quantum vacuum, however by changing it, one also changes the scale of any references one could use to measure such differences. I suppose you could say that it postulates that the quantum vacuum puts matter in its place so that space can exists. If you missed it look for a posting I did on how Casimir plates might be argued to be used a preferred reference frame if this quantum vacuum did not increase an an equivalent way. Gravitational contraction ignores the idea that space itself could increase. or 'space-time'; both of which I guess you consider (that 'curve' word!) What led me into the idea of how a white hole should appear was the question of examining how an astronaut in orbit around a black hole and or traveling with a light beam through a gravitational lens might or might not be able to observe the curve in the light paths using material tools. If you were for example to put a space craft into an orbit where the light paths will also orbit the same object, 3m in the case of a black hole, and then attempt to model how our astronauts could or could not observe the curved path of the light by letting it travel through the craft while also using a rigid ruler, one then examines how the two different predictions would work. Its important in these gadenkens that the craft would also be stabilized by gyroscopes otherwise his rotation would allow a valid argument to show how he would observe this curvature in the light, however if one cannot use gyroscopes to detect this rotation then it cannot still be considered rotating in the frame of reference of our travelers. This rotation is slight and is of the same sort that one would have by keeping a satellite facing towards the earths as it completes its orbits. The point is that if one can somehow show that our astronauts rulers must also curve to match the light paths then one can also show another example where even curvature itself is relative. One gets similar prediction using an accelerating elevator gadenken giving two observers different observations when they attempt to measure the light path. The accelerating elevator observers will insists that the light path curved as it passed through the elevator, while our non accelerating observer sees the light unaffected . Pushing this whole speculation to the extreme where one passes by this 3m level, "where the light would have originally been bent to the point where it could in principle travel completely around the black hole" and if our astronaut would now also insisted that its actually flat from his prospective, and then try to determine who is right, gives an interesting possibility that it doesn't end here. If it dose appear to curve in reverse for him as he dips below this level, should also suggest that it could appear to pinch off into a curved surface that now appears to repel gravitationally. However how he would observe the other parts of what our outside observers would agree was a circular event horizon becomes even more speculative because of the way our astronaut traveler can only observe small parts of what now appears to him as a white hole, at any one time and place. A continued space expansion from our astronauts prospective i.e., light cones, could then be used to argue how this surface becomes censored from his ability to observe this reverse curvature in its entirety. In the theory I promote it gets more complicated because of the way our traveler is also now measuring a smaller area of space because of the way all his references have also become shrunken relative to our prospective. That would mean that our astronaut is in actually measuring a smaller area of curvature making the difficulty of measuring such curves in the light paths even more difficult. Keep thinkin Jim G |

Roy, about now the Big Bang Theory arguement has changed so much from the concept of an expansion coming from a singularity, producing a universe of a particular age, dimension and history, that the term should be altogether scrapped! You'll notice that supporting posters even talk in terms of infinity (an oxymoron to BB), and their squirms to explain isotropy and homogeneity in an expanding universe are breathtaking in the leaps of logic. Mind you, "logic" in the eyes of a Big Banger is the ability to jump at will from one 'frame of reference' to another- as it is with the DHRs A while ago, it would have been unusual to get even a shrug from a BB about the view out from the edge of the universe (or most likely, screaming and supercillious abuse); now the possibility of the view being the same as ours (thus taking the universe to infinity) is accepted by many as a given. (The guy in "Lord of the Ring" fought on like that with an arrow in his heart, but he still died-- bring on a similar fate for the the Original Theory) Jim G |

Bull**** meter quivers and it isn't even uncrated yet. Albert (are you descended?) I once worked for a mining exploration company. We drilled bore holes down which the 'logger' sent a probe to measure the radiation level (we looked for uranium deposits). The logger had to set his probe for back ground radiation, before starting his test. On one occasion, he thought that something was broken, as he couldn't set to zero; the needle kept going off the dial. After a hold up of several days, and two factory rebuilds of the probe, he realised that we were standing in the stuff!! So the next time your meter quivvers, check your boots!

I wish I could get my mind around how it translates to 3-D, but I guess I need lots more math than I have. LOL It is not so much math here, although that would no doubt make it clearer. Try this. Imagine a series of balloons, inflating from a point. Say the ratio of radii of each "onion skin" is a constant. Now let light be emitted from any particular layer of skin, and pretend that it propagates a little more quickly than the various layers expand. The outermost layer (*now*, since we don't yet have reliable light-based information from tomorrow) would get the emitted light some long time later, from a layer that is no longer in that position. The source layer would be expanding less slowly than our layer currently, so the light would be red shifted.. As tadchem is wont to say, parables are like ropes. You can pull them a little, but you can't push them too far. One other quick question (which may show my extreme ignorance, but what the hell): If the BB started at a single point, when and how did the universe (or our portion of it) transition to what it is now? Instantly? After inflation? The current belief is that it expanded from a singularity. As if this could be what the inside of a Black Hole might be like. The "red shift" that I described above (a series of expanding balloons) is *not* truly velocity based, but more "change in gravitational potential" based. The past had a very high mass/energy density, compared to *now*. So, just as light is red shifted when generated on the Sun as compared to the same reaction *here*, the light generated *then* is red shifted as compared to *now*. I went through most of the stuff that Mr. Wormley provided, but.../shrug/...what can I say? Most of it was over my head. Heck, as a layman I think I understand quantum physics better than I understand Cosmology. LOL It is so big, and trying to understand how the Universe is "shaped" while not being able to get outside and look at it... We just aren't constructed to do that without some thought. *That* is where the math helps. Thanks again, David! As frustrating as this is to get a handle on, it's still fascinating. Amen. David A.
