Thanks. Unfortunately I'll have to wait until my "free article" count with NYT resets. Meanwhile there will be new thread on the astrophysics bear.

It's an amazing discovery, just as Einstein predicted.

Re: Event Horizon Scope and Sagittarius A
the only thing I don't understand is the orientation of the black hole in relation to us?

Re: Event Horizon Scope and Sagittarius A
That's one interpretation of orientation: position on the night sky. The other possible interpretation (which is the first thought I had when reading the original Q) is: what is the direction of theKanadalainen wrote: ↑Fri May 13, 2022 2:00 ammessier 111 wrote: ↑Fri May 13, 2022 1:50 am the only thing I don't understand is the orientation of the black hole in relation to us?

Re: Event Horizon Scope and Sagittarius A
The discovery paper is open access and there is no preferred orientation for Sgr A*.

https://www.constellation-guide.com/sagittarius-a/BH 's spin axis w.r.t the plane of the sky at its location. I am curious to find what that might be. I think I'll have to read the paper, but from the images I see only vague hints.

Any metaphor will tear if stretched over too much reality.
