I asked some questions regarding the equivalent neutron mass of the universe now as compared to the infant universe in a thread fairly recently. PM prompted me to qualify these questions and the best I could do at that time was to refer to ‘charge management over a 3d vacuum’. In order to divulge the intention of this term I have come up with a question or two that may illustrate the idea with attention to detail.

First is the matter of orbits within galaxies that are disparate with calculations that have prompted the DM question. Could this observation be governed by SR? We understand a degree of the nature of gravity with respect to massive bodies. Can we automatically assign these properties in the same value to the supra-massive structures of BH’s? As electro-magnetism is the product of SR FoR, could this orbital anomaly be produced by mass that is above the Schwarzschild radius? ie, is it a product of the Lens Thirring effect?

As EM generation is produced by disparate FoR’s, does that then mean that one cannot block the generation of a magnetic field produced in a standard electromagnet by shielding the current from the magnetising material?

I’m not sure what you’re asking here.

> equivalent neutron mass of the universe now as compared to the infant universe

See “Mass of the universe” thread.

> charge management over a 3d vacuum

Huh?

> orbits within galaxies that are disparate with calculations that have prompted the DM question

I follow this. Baryonic matter is insufficient to explain the orbits of stars and star clusters within galaxies.

> Could this observation be governed by SR?

No. Speeds are far too slow for any SR effect. Unless you’re pointing to MOND or similar, and that opens up a new can of worms.

> We understand a degree of the nature of gravity with respect to massive bodies. Can we automatically assign these properties in the same value to the supra-massive structures of BH’s?

Yes. Although here we’re talking about GR rather than SR. Further, the distribution of BHs in galaxies is totally wrong for explaining dark matter effects, and that’s true no matter whether you are talking about super-massive, stellar mass or micro BHs.

> could this orbital anomaly be produced by mass that is above the Schwarzschild radius? ie, is it a product of the Lens Thirring effect?

No. The number distribution of super-massive and stellar mass BHs is totally wrong for explaining this orbital anomaly.

> As electro-magnetism is the product of SR FoR. EM generation is produced by disparate FoR’s.

No, although spinning charged BHs do have a magnetic and electric field. Are you getting this mixed up with the Unruh effect?

> one cannot block the generation of a magnetic field produced in a standard electromagnet by shielding the current from the magnetising material?

It can be blocked by a “high mu material” such as Mu-metal

PM prompted me to attempt to sum up what I was trying to evaluate.

No. Speeds are far too slow for any SR effect. Unless you’re pointing to MOND or similar, and that opens up a new can of worms.

I don’t think I have this mixed up with Unruh and the last 3 questions you have answered here are interelated. I wasn’t questioning whether BH’s are producing an EM field, rather, could another type of field be generated through SR FoR disparity(maybe they have an electro-weak field or something)? Can a particles FoR when it is beyond an EH be of any equivalence to that of one outside

Interesting. Cheers.

Have I got it right that a mu metal will absorb the field energy generated but not actually block the SR FoR disparity from creating the field in the material exposed to the presence of a current?

hmmm…. where am I going with the question on neutron mass evolution?

Scenario: Universe has reached heat death(woooo ooo). What would be the result to the remnant cold matter universeif there were a rapid decrease in electron mass within it. The cause of electron mass is not crucial to the question but if it helps let’s suggest that the presence of electrons is reliant on a threshold universal EM field density and beyond heat death this cannot be sustained. Would this collapse the universe?
