Assuming that the effective mass of a photon also produces a gravitational force, then the force times time this exerts on the mass is half the momentum change of the photon, and so momentum is not conserved in gravitational bending of the path of a photon. If we assume instead that the photon's effective mass has no gravitational effect, the violation of CoM is twice as much, since the momentum of the photon is changed without affecting the momentum of the matter creating the gravitational field. <br /><br />I wonder if anyone else has noticed this blatant violation of CoM?Simon Derricutthttps://www.blogger.com/profile/15137826634256652580noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-64742556645986679182021-03-15T07:02:12.390-07:002021-03-15T07:02:12.390-07:00Another tact you could use as opposed to "fak...Another tact you could use as opposed to "fakematter" is to join in with the fakery. QI is the latest dark matter candidate. It requires no new particles and is the only dark matter candidate that has any positive lab results. Dark matter has finally been found and it's been right in front of us all this time! Becoming a dark matter candidate will make getting published much easier and you can get millions in funding.Germhttps://www.blogger.com/profile/00742015426098209175noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-61034429463898253762021-03-15T07:02:11.316-07:002021-03-15T07:02:11.316-07:00Mike - I've previously put forward the idea th...Mike - I've previously put forward the idea that it's the progressive slowing of time in the vicinity of a mass that results in the effect of gravity. If you consider a plane wave passing by a mass, then there is is a time gradient with the wave closer to the mass being slower and with a shorter wavelength. The wave is thus deflected simply by the time gradient. Your equation cr/cinf = 1-(2GM/rc²) can thus be used to define the rate of time slowing, or alternatively maybe the matter-wave density if we assume that time is slowed proportional to the matter-wave density. That matter-wave density suddenly hits zero at the Hubble radius, though, so in fact c(infinity) should really be replaced with c(Hubble radius) instead. Outside that radius we can't define c and we have no way of knowing it either. <br /><br />Being able to derive the same relationship via different methods is useful. It may not tell us which is the more-fundamental explanation of the effects, but at least gives the feeling that things hang together and that the relationships are likely to be true. <br /><br />Your gravity derivation predicts an abrupt drop-off of particles above the Planck mass, and that particles below that mass are not gravitationally attracted. This seems to clash with the experiment using individual neutrons in a gravitational field (Nevizhevsky et al, 2002). Also it seems photons do see an attraction on their mass as well as the wave-deflection above. Also note that Einstein's equivalence principle is shown to be false by the extra deflection of a photon in a gravitational field as opposed to a frame acceleration. Can't get away from some paradoxes yet.... Another paradox with Unruh waves is that an infinite-velocity wave cannot exist as a wave, since it would be the same phase at each point and thus has no wavelength either. <br /><br />I figure with the paradoxes they'll get solved, and in the meantime if the equations work out and the experiments work then we're on the right path. It seems likely that infinities do not actually exist, so equations with infinities in are a bit wrong. Thus there may be a few Planck-time delays in those waves in reality, but we can't measure them. <br /><br />Normally, the horizons are equidistant. Your experiments break that symmetry, and bring one a lot closer. Break the symmetry, and you break the conservation law that results from that. <br /><br />Sorry to bring half-formed ideas to the party, but maybe it helps in that someone can push them the rest of the way.

A quote from the paper that shows this is just another fudge: "the velocity profile is a function of the 3 free parameters a, b & rs. These parameters can be varied so that β(r) fits the observed galactic rotation curve".

A quick comment on, "Dark Matter"...Mike,<br /><br />A quick comment on, "Dark Matter":<br /><br />When a concept does not derive from logic it is hard to refute, as you have been trying to do, using logic. What is more likely to succeed is to use rhetoric, the basis of "Dark Matter", to slay the beast. In that vein I would simply recommend that the term "Dark Matter" be referenced by its equivalent definition, "Fictitious Matter" or more in keeping with a similar politic problem of this day, "Fake Matter". <br /><br />Trying to use logic against rhetorically derived self serving concepts has little probability of succeeding. The gestalt shock of hearing the "Fictitious Matter" might just jar loose any brain cells in the pious proselytizers for "Dark Matter". This, call it what it is technique, has certainly been successful in the political arena in awakening the people about the real nature of the "News Media". <br /><br />Keep up the good work,<br /><br />Jimmy Johnson Jimmy Johnsonhttps://www.blogger.com/profile/01547827814143221950noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-58627661024552118622021-03-13T16:45:40.892-08:002021-03-13T16:45:40.892-08:00I just became aware of the other type of gravity f...I just became aware of the <i>other</i> type of gravity from GR, the gravitomagnetic field... which is only caused by mass in motion, and results in frame dragging, etc.<br /><br />I'm no physicist, but how does that fit into all of this?

If it doesn't, then that would imply different values of H0 and/or the lensing mass distribution to give the observed results.
