I thought dark matter had been figured out. When you eliminate everything else, the only thing left is that dark matter must be pure gravity. That would explain its properties.
I'm still having trouble with only being able to see the portion of the shell that is "edge on." Why can't we see the rest of the sphere. Wouldn't it just look like a giant ball?
Great analysis. I have one question. Why is the material only blowing away from one plane, such as an equator? Why doesn’t it blow off evenly from all over the star?
So, what this looks like is gas being emitted from the equator of WR 140, and it is pulsing. The planet may be “coming apart” around its equator and then going back together. The gas is emitted, then it is stopped, then it is emitted.
