  1. does a smaller kerr bh have a more extensive frame dragging radius due to a higher gravitational gradient than of a larger one?
  2. so there would be some sympathetic rotation of the dm within a small finite range of the kerr bh event horizon, and would that range be larger with a smaller bh than of a bigger one?
  3. Would a cavendish experiment in our galaxy's dm halo have a measure of G different from that measured on earth?
  4. so....dm does rotate somewhat somewhere near the kerr hole, unless dm ignores space time, or is a minority variant species of space time itself.
  5. if the proximate dm has rotation matching the kerr bh frame dragging and extends that effect out at the 1/r^2 distance, and gravity effects being of infinite range, doesn't that infer a declining dm rotation rate extending into the galactic visible mass?
  6. about frame dragging...how extended from the event horizon is this effect predicted to occur?
  7. near a rotating black hole and in the presence of DM, wouldn't a rotation of the proximate DM occur in the same direction of the bh due to frame dragging?
  8. frame dragging...could the collective mass of a galaxy exhibit a small potential for this, or at least at the vicinity of the central black hole? If DM particles have a non zero interaction, however small, wouldn't that offer a mechanism?
  9. on my question of why the DM halo doesn't follow along with galactic matter......since there is a gravitational reaction between the two, why not? Shouldn't they eventually sync up in some form?
  10. is the galactic DM halo proposed to orbit along with the same speed and direction of the visible matter in our galaxy?
  11. thanks mordred, If the overrall density tends to a certain smoothness, and due to an inherent property of non clumpiness, cannot form "clouds" anywhere in the galaxy, I see that as correct. The question of why G is somewhat indeterminate was the source of the question. I had thought that low freq. gravity waves might be a factor sometime back, but was shown to be incorrect.
  12. with these estimations, and if the distribution is inconsistent on small scales, does our particular vicinity within the galaxy allow the possibility of a "dark matter weather", in that within small regions, perhaps "clouds" of DM pass through the earth at various times, and contribute to the small variations in the value of G measurement?
  13. does our galaxy have a dark matter component that has been estimated as to amount and distribution as of yet?
  14. the original thread seems to indicate that the concepts of math divisions and time intervals are closely linked. Why can't math be "infinitely divided" and time composed of blocks of those infinite bits, therefore time being intuitionist and the bulk infinite? When I say the bulk is infinite, I mean it is heading to infinite, and will do so forever, perpetually subdividing down, so the bulk is at once intuitionist, but trending infinite and time is independent of those underlying actions, and functions in intuitionist status.
  15. it seems as though the particles appearances are too brief to register in this domain of reality, so as to be said as not be not there, which they are shown to be by the casimir experiment. Nothing lasts forever, so why say things don't exist simply because they exist at the lower boundary of lifetime duration of a particular material property?
  16. ...so, it from bit then...
  17. if the particles are mathematical abstractions, they seem to have a physical presence in certain tests until they are "borrowed back".
  18. not real? then what is the source of the casimir force?
  19. to simplify matters...what if there was only one particle emitted as borrowed energy instead of a pair, and it bumped into other particles of space, and those interactions determine the annialations ....and... What if a single particle appeared into a void, and no other particles existed, causing it to express maximum energy since nothing else was there to prevent that from happening...wouldn't that be a model for the big bang?
  20. as I understand it, space is composed of two virtual particles appearing, then annialating, as borrowed energy, but do these pairs originate from the same source? If they were omitted at that same point, why would they have been differentiated in the first place? Wouldn't they have "pre annialated"? Were they cancelling each other out until physical separation allowed their respective properties to materialize?
  21. there is a fairly recent online lecture some may find interesting : Fabrizio Pinto - Casimir Effect Propulsion Applications - You Tube.
  22. thank you MigL, I am fairly aware as to how systems such as these are detailed, and follow the ideas as best I can, and I expressed the dual matterwave idea so as to attain a visual picture of what is happening, in order to build up an intuitive understanding of these matters. Of course it's a clumsy mechanistic approach and realized it's pretty laughable when I wrote it, and thankfully the responses have been quite civil.
  23. thank you for the response. To the degree I understand it, it seems a valid criticism.
