EMOND....going beyond MOND?

[trinitree88]

The authors propose a modification of MOND that covers all mass discrepancies, both in galaxies and galaxy clusters. SEE:http://arxiv.org/abs/1207.6232

Interestingly, with this “extended MOND” (EMOND)
formalism, Gauss’ theorem (or Newton’s second theorem)
would no longer be valid in spherical symmetry. This
means that masses outside a sphere can affect the local
gravitational field strength....

Hmm....

Hmm....

Cougar. Hmmm also. That'd mean that if you took one of our modern Cavendish type set-ups, dropped it gently down a convenient mineshaft....(Homestake?)...you'd find a different but measurable value of G. Since they just explained away the anomalous Voyager acceleration, I'm not jumping too quick at this. pete

Do you mean the Pioneer anomalies?

The possible solution is only an uncalibrated guess. I have read, but never seen documented that the EotWash Cavendish-like tests produced curious results in a deep mine shaft; but I have nothing to support this.

Generally speaking, the new framework actually needs two interpolating functions, and two fundamental constants defining their transition domains.

Generally speaking, introducing two new parameters to right an apparent problem at great distances is an iffy solution; although tying it to a deep elevator Canvendish would be precious. We should be able the devine the same information in an elliptical solar Cavendish experiment. Let's do it.

Jerry. Yep. Pioneer tis. my bad. tore up my knee playing golf and didn't sleep all that well Thurs nite. Double dumb. lol pete

The Pioneer anomaly has been explained simply by thermal radiation. There is a recent publication which says this. So any theory seeking to explain it via modifications to gravity seem a bit surplus to requirements.
