When I said “ray” I just meant an imaginary line that could be drawn to extend in a given direction, not a literal particle escaping. It was mostly to think of a way you might conceptualize an orientation of an object that may not have any dimension. As in, if the matter just outside a singularity rotates, perhaps you could consider it to rotate? But I’m not sure that would be accurate to say anyway. My grasp of the physics of black holes is obviously pretty loose. :)

Thanks for taking the time to explain!

Technically couldn’t a ray emanating from a singularity rotate? Like, the point could have a sort of orientation without having any real measure?

Not saying that’s the case here, but I think it could happen.

All through grad school, my running joke was that “Teen Talk” Barbie did nothing wrong. Math class IS tough. 😭

Depends how many holes you have in your socks. :)

Or whether your coffee cup has a handle.

Aptly named!

That’s encouraging. Hopefully they’ll give it up. It’s ridiculous that anyone pursued this in the first place.

Much appreciated!

Thanks! I’ll check it out. Still figuring everything out. I’m not sure I know how to cross post here yet - unless it’s literally just posting the same image again?
