I follow you, I promise. The gravity "hole" in the Indian Ocean is not the result of mountains or trenches or any other "crust" formation. Although these things do result in variations in the amount of mass nearby, I am talking about something else. In the mantle are measured (I guess by sound from earthquakes and such) to be these "giant structures" of "increased density". , , There appears to be a large plume of magma that had erupted from the mantle into the crust resulting in the anomoly in the Indian Ocean.
Perhaps a better way to make my suggestion would be to talk about the "Great Red Spot" on Jupiter. What is that?? Does it have different gravity? Could such a formation exist in the Sun???? What would that be like?? ANd,, Jupiter is SO ENORMOUS ,, could there not likewise be such "storms" deeper within Jupiter which although connected to other parts of Jupiter do no necessarily "reveal" themselves to us?
I forget about this other star, but there are a number of stars with varying brightness, although there are multiple possible explanations. However, this was a study proper that analyzed the spectroscopy of the data and apparently it appeared as though there was indeed a "non-mixing" of the elements of this particular star, so that on one side burned the color of one particular material, while on the other side burned the color of another one. In this case, the density of SUCH A HUGE OBJECT ,,, A STAR ,,,, must vary in a way that is not necessarily stable in it's gravity correct?? Given enough time, the whole thing should settle down to an energy-less mass perfectly sorted by gravity, but perhaps this just really takes a long time? So long, in fact,, that we might be able to imagine that within the sun, there are also "structures" that exist similar to our own uneven mantle mass distribution?? Huge formations (perhaps storms like the one on Jupiter's outer visible atmosphere) that are simply yet unable to mix into the rest of the Sun's mass, despite their instability against the Suns gravity?? Perhaps so huge that instruments might even be able to detect a gravitational variance that it might cause?
