Walker, Abraham Loeb<br /><br />(Submitted on 6 Jan 2014 (v1), last revised 28 May 2014 (this version, v2))<br /><br />In the standard cosmological model, the Universe consists mainly of two invisible substances: vacuum energy with constant mass-density rho_v=\Lambda/(8pi G) (where Lambda is a `cosmological constant' originally proposed by Einstein and G is Newton's gravitational constant) and cold dark matter (CDM) with mass density that is currently rho_{DM,0}\sim 0.3 rho_v. This `LCDM' model has the virtue of simplicity, enabling straightforward calculation of the formation and evolution of cosmic structure against the backdrop of cosmic expansion. Here we review apparent discrepancies with observations on small galactic scales, which LCDM must attribute to complexity in the baryon physics of galaxy formation. Yet galaxies exhibit structural scaling relations that evoke simplicity, presenting a clear challenge for formation models. In particular, tracers of gravitational potentials dominated by dark matter show a correlation between orbital size, R, and velocity, V, that can be expressed most simply as a characteristic acceleration, a_{DM}\sim 1 km^2 s^{-2} pc^{-1} \approx 3 x 10^{-9} cm s^{-2} \approx 0.2c\sqrt{G rho_v}, perhaps motivating efforts to find a link between localized and global manifestations of the Universe's dark components.qraalhttps://www.blogger.com/profile/13436948899560519608noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-83261106196042344322015-11-02T14:34:36.073-08:002015-11-02T14:34:36.073-08:00Czeko: The standard explanation of Unruh radiation...Czeko: The standard explanation of Unruh radiation is that a Rindler horizon splits up ever-forming zpf virtual particle pairs so the unpaired particles become real, but I'm moving towards an informational understanding and I can derive the usual formula like this: when a Rindler horizon forms it reduces the uncertainty in position Delta_x, so by Heisenberg Delta_p must increase. Since E=pc, energy is produced. Energy from information loss.

Fresh air, open moors, lots of time to think: 'Zen and the Art of Motorcycle Maintenance', 'Not all who wander are lost'..etc.<br /><br />I've been trying to get gravity into the MiHsC framework three ways: 1) using sheltering, 2) from the uncertainty principle involving interactions between Planck masses (published) and 3) from changes in horizon areas. You're suggesting a mix of 1 and the interaction part of option 2, which is the way to go: IMO the answer will use all three, but the maths seems to be suggesting something further than my intuition can go at the moment. I can get G in F=GMm/r^2 to within half a percent, but as I said it falls flat because I lose a dimension.

Two massive particles at distance <i>r</i> will block respective waves from the other's horizon that have a node at it's partner, causing an equal pressure pushing them together. Obviously, <i>r/2</i> will have more nodes and thus more pressure. But this is only a linear relationship. The inverse square law comes into play with gravity because QM implies that the number of long waves increases with the surface area at a given radial distance, however linearly fewer wavelengths will have nodes as that wavelength increases, generating an inverse square relationship for sheltering.<br /><br />And the empirical <i>m*m</i> term is due to the round robin of sheltering, since particle A1 shelters B1 and B2, as does A2 shelters B1 and B2, for four pairs of sheltering to produce the force, which matches the Newtonian description. B1 sheltering B2 produces no net force towards A and vice versa.<br /><br />This has some implications with high acceleration away from large bodies as well as providing an explicit mechanism for mutual acceleration (I didn't have a mental image of that until now). For example, like you've said, a ring with mass rotating fast enough would experience no gravity from bodies above/below the axis of rotation.<br /><br />I have a feeling though that Mike's derivation is a bit off from my incredibly rough picture here, though.Analytic Dhttps://www.blogger.com/profile/14307179997233629815noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-85325572387590044752015-10-28T14:45:26.637-07:002015-10-28T14:45:26.637-07:00Mike, reading your comment, I imagined this situat...Mike, reading your comment, I imagined this situation:<br /><br /><i>On the street</i><br /><br />Police officer:<br />- Sir, is this your dimension?!<br /><br />Mike:<br />- Why, thank you very much.
