Weak Solar Convection 100 Times Slower Than Predicted

An anonymous reader writes about an observation that convection in the outer layer of the Sun seems not to behave how it ought to: "These new findings based on SDO imagery, if verified, would upend our understanding of how heat is transported outwards by the Sun and challenges existing explanations of the formation of sunspots, the magnetic field generation of the sun, not to mention the concept of convective mixing of light and heavy elements in the solar atmosphere. 'However, our results (PDF) suggest that convective motions in the Sun are nearly 100 times smaller than these current theoretical expectations,' continued Hanasoge, also a postdoctoral fellow at the Max Plank Institute in Katlenburg-Lindau, Germany. 'These motions are indeed that slow in the Sun, then the most widely accepted theory concerning the generation of solar magnetic field is broken, leaving us with no compelling theory to explain its generation of magnetic fields and the need to overhaul our understanding of the physics of the Sun's interior.'"

      That the shapes and spins of galaxies can be shown in simulation by collapsing parallel electric filaments ("pinch" effect), p. 26.. In contrast, from what I understand, you have to introduce a majority of dark matter & energy into such a simulation to get a stable galaxy if the stars interact otherwise with only gravity.

      Something I'm looking at that's related to this:

      http://en.wikipedia.org/wiki/Millennium_Run

      It runs an N-body particle solver using gravitational interactions, to run the cosmic microwave background "forward" to see what kind of modern universe it should develop. This produces the pictures of the filamentary large-scale structure of the universe that I've become accustomed to seeing in recent years, but it turns out you can use the same software to model both radiative and magnetic coupling effects. Here's a variation showing how radiation changes stellar evolution:

      Same basic large-scale structure, but different number of "stars", different brightnesses, speeds, etc.

      No, your source is lying.

      In 1986, Peratt published two Plasma Cosmology (NOT Electric Universe) papers, reporting the results of some simulations (similar to, but not quite the same as, what you wrote). However, these were not simulations of real galaxies. Why not? Because real galaxies contain stars (duh!), whose motions ("spins", to use your term) cannot possibly be represented in Peratt's simulations (stars have charge-to-mass ratios vastly different from the ions Peratt assumed, in his simulations).

      Worse, real galaxies do not have double nuclei with the same shape as those in Peratt's simulations. And so on.

      Hm, I think you're missing my point... I wasn't supporting their claims as more correct than a gravitationally-based cosmology, just noting that they seemed to be making reasonable conjectures, albeit non-mainstream, and that they didn't deserve to be called names. I said:

          "That seems reasonable; correct or not is a matter to be determined."

      The same can be said about dark energy/matter. Reasonable, but correctness TBD. It is problematic for a simulation to not model all know behaviors of a system, but nonetheless, we do it all the time and often find useful models in them.

      Agreed, this is better termed Plasma Cosmology, not Electric Universe as that appears to be commercially co-opted; maybe you're reacting more to that; I was reading more of the folks they cited than the .info website. More:

      At least, none which has any quantitative, internally consistent legs to stand on.

      "Agreed, this is better termed Plasma Cosmology, not Electric Universe [...] I was reading more of the folks they cited than the .info website."

      Then why not say so? Why give airtime to folk who, not to put too fine a point on it, are deliberately lying? Who might, therefore, be reasonably called crackpots?

      "That seems reasonable; correct or not is a matter to be determined."

      Yes, it (the PC stuff) may indeed seem reasonable. However, it has long since been determined that it cannot possibly be correct. Or, more precisely, every single one of the principals involved in those efforts is either dead or has stopped doing research into showing that the reasonable-sounding ideas actually match the relevant, cold, hard, objective, quantitative astronomical data. For example, Peratt has published nothing new, on this topic, since the late 1980s (yes, he's published stuff, but none of it involves new research), and Lerner's last work on this seems to be sometime in the 1990s. In the meantime, the quantity and quality of the directly relevant astronomical data has grown enormously, from the WMAP results to the thousands of hours of Hubble observations to the SDSS to data from Spitzer, Herschel, Chandra, Fermi, WISE, ...

      Don't you find it odd that, given the tens of thousands of hours EU and PC proponents have spent promoting their ideas on websites across the internet, and given the hundreds (thousands?) of ardent fans, not a single one has done anything to develop these ideas, on a scientifically-sound basis?

The hydrogen seen on the surface of the sun may not be representative of what is below the surface, same as much of the earth is covered with water, but only a mile deep. The core of the Earth may be heated by a similar boudnary evaporation and LENR process? The universe may have a lot more iron decaying into hydrogen than hydrogen fusing into iron...
