Turbulence in General Relativity

Thoughts:

Turbulence in GR is linear and hence does not give rise to cumulative gravitational effects. Indeed, the power that can be transmitted using GR as a factor of the ‘gravity caused’ is immense. For instance: at the power transfer of energy at the Schwinger limit (here I assume 3×1029 watts/m2), the non linear effect – the gravity term is very low.

Say (see http://arxiv.org/pdf/1007.4306v3.pdf) 3×1029 watts/m2 (at optical freq).\

Consider a 1 metre3 box with perfect mirrors at the schwinger limit – how much does that much radiation weigh?

I get 1×1021 Joules per cubic metre at any one time, so that’s 11.1 tonnes. (http://www.wolframalpha.com/input/?i=10%5E21Joules%2F%28c%5E2%29)

That seems like a lot of mass, but 11 tonnes in a cubic metre is not going to alter the static gravitational field much even in the low field limit like that of the earth.

That 11 tonne figure is interesting, as it is also the density of lead. Its strange (or not) that the Schwinger limit is also the density of normal matter.

From the book I am reading now: ( Fields of Color: The theory that escaped Einstein  — Rodney A. Brooks)

 

“… spin is an abstract mathematical concept that is related to the number of field components and how they change when viewed at from different angles. The more field components, the higher the spin.” 0  ,  1/2  ,  1  , 2  are the spin values so gravity has more field components. Can we mimic a field with a lower number of field components with one that has more field components? Yes. So we generate everything from gravity.

Einstein was of course worried about the electromagnetic radiation emitted from a classical Bohr atom. But I have also learned that he was worried about the GR radiation from that same atom that he claimed was ‘not observed’. I think that the waves would be of very low energy but I should work that out. (re – replenishment from the turbulent gravity).

Random Q: Were there about 5 times TOO MANY GALAXIES in the early universe – which would jive with my thought that dark matter is matter gone dark. In the early Universe matter was packed too tightly for there to be any dark stuff, so there was more galaxy formation. A: Possibly see for instance – http://astronomynow.com/2015/11/21/hubble-survey-reveals-early-galaxies-were-more-efficient-at-making-stars/

Random Q: Frame dragging. Would any other physics change over one of Tamjar’s rotating superconductors where he sees anomalous gravitational effects – i.e. look at decay rates of common isotopes, etc.

 

Random Q: There is the experiment in Italy where they see decay rates changing as the year advances, which is anomalous. Wonder if some frame dragging can take care of that.
