would be very strange if it turned out right

like Kepler

 

for years everybody is assuming circular or spherical symmetry because that is almost right, and then some dude comes along and notices that it is not quite circular it is more like elliptical whoah!

 

and this explains something about the CMB?

 

maybe someone would like to discuss this.

I'm not sure I understand the implications of that. If the "shell" corresponds to one point in history, and it's elliptical, doesn't that mean light would have to travel slower along the short axis? That can't be. Maybe the expansion of space is non-uniform somehow? Or that cosmic microwaves don't all originate from the same time period? Why would it be an ellipse?

 

I guess the question is, has this moved beyond the stage of just the math working, to some kind of an actual explanation for why it would be so?

they offer a physical explanation that involves a very weak magnetic field.

I don't understand their idea yet.

when I get some answers i will get back to this.

it does not involve weird stuff like a different speed of light

AFAICS they are using ordinary physics (to the extent that they have an explanation)
