>"In 2012, a mathematician named Stefanos Aretakis—then at the University of Cambridge and now at the University of Toronto—suggested that some black holes might have instabilities on their event horizons. These instabilities would effectively give some regions of a black hole’s horizon a stronger gravitational pull than others."

PDS: This seems to make a lot of sense, from a logical perspective...

If Suns (centers of great gravitation, aka "Gravity wells") -- can have solar flares, then why can't an object of pure gravitation have "gravity flares"?

Especially if gravity turns out to be a wave -- as has been recently conjectured by many scientists...

That is, gravity "flare-ups", different "pressures" of gravity (think fluid dynamics) -- in different localized places at different times?

Like sunspots...

These "gravitational hairs" (probably vortices, because everything in physics seems to simplify to a vortice or vortices of some sort, if you "peel back enough levels of the onion", that is, remove as many layers of man-made concepts and abstractions as possible -- atoms and all the sub-particles are in this category of object, as is force itself, as is energy itself, because all force is energy -- also, another name for vortex is "spiral" from which the word "spirit" is derived, and there's the millenia long-"missing link" between spirituality and the hardest of hard physics, in other words, it does or will unify these two disparate fields of human thought), but these "gravitational hairs" aka "gravity flares" aka "gravity vortices" aka "localized pressure gradient of gravity" -- probably exist.

Now, here's the kicker of all of this...

It would be interesting, highly interesting, for scientists of the future (since I see no way possible of this being accomplished at this point in time, but maybe someone can prove me wrong or give me information that I did not yet have at this point in time), but for scientists of the future to:

Measure the gravity of the sun in a local region, at the place and point in time -- of a solar flare.

Why?

See, I'm betting that there might be a relationship between the local gravity of a point on the sun -- and the solar plasma which is emitted

In order to do this, scientists would first need to be able to measure local gravity at a point on the sun and be able to differentiate that local gravity with respect to other points. This (at this point in time, to the best of my limited knowledge) -- is no small task.

OK, well, if that can be done... then the next step would be to see if there's a correlation with solar flare activity.

I'll bet there is.

I'll bet that the Sun's solar flares -- are correlated with the Sun's local gravity.

I'll also bet that sunspots -- are also correlated with the Sun's local gravity...

Now, either of these correlations -- might turn out to be an inverse correlation, that is, if you have more of one thing (for example, localized gravity), then you might have less of the other (solar flares or sunspots).

It would also seem that solar flares and sunspots are opposites in and of themselves, which would imply that if let's say, there is less local gravity in the region of a solar flare -- then there will be more local gravity in the region of a sunspot.

Or, it could be the opposite! -- That is, if there's more local gravity in the region of a solar flare, then there should be less local gravity in the region of a sunspot...

Well, whatever the case, I leave it for scientists to determine if there's a relationship there (it seems very logical that it should exist), and if so, what the exact relationship is...

In closing, I should point out that sunspots, solar flares, and even gravity (and even electricity!) -- will probably turn out to be vortex phenomena -- just vortex phenomena at different scales.

Also, if we could determine a link between solar flare plasma and the sun's local gravity at that point in time, if there's a relationship there, then that's the first step in using plasma fields to engineer gravitational ones (perhaps Star Trek had it right all along!) -- which is one of the first baby steps towards an actual functioning Warp Drive...
