There are no black holes in the universe at all, there are only spherical celestial bodies, the images of so-called black holes are annular eclipses

It looks like everyone thinks I drew the three-view drawing of a so-called black hole wrong, OK.

Can anybody draw a correct one of it for us?

Have you read any of the literature regarding black holes? There is a huge body of knowledge on these objects and simply trying to draw one would tell you absolutely nothing.
Can you draw an electron? Or gravity? Or some quark gluon plasma? How about a spherical galaxy? Will that be a sphere do you think, like a football? That's great, what does that tell you? Anything useful?

Black holes were theorised first, there is a lot of important work you need to catch up on regarding that and DaveC426913 posted information on that, have you read it?
Please read it.
There is observational evidence regarding black holes have you read any of that?
I referred to that in post #4 a lot of posts ago.

This is a science platform with contributors who will guide you and educate you on certain topics.
Not all the contributors are experts on General Relativity and black holes (like me) but we can cite text books and papers of interest.
We can push you in the right direction even if it just a wiki page.
You need to take this on board.

Thank you.

I really have not read them.

But as an object, it should be able to be displayed by a three-view drawing.

Does a black hole like a movie, it can only be viewed in front of it, and can’t be viewed at its side or on its top?

Spherical, what does that tell you?

I know you are a very good man, and I thank you very much for your kind words.

But there is not a single object at all that can be viewed as a ring of light in its front and can be also viewed as a ring of light on its side.

That case violates solid geometry.

These are not ordinary objects.
 
This is a model of how a black hole should look from different viewing angles.
The model was shown in a video clip, shown on the Harvard University site sometime back.
That Harvard page now seems to be buried, I can’t find it.

I made a small animated gif from part of the Video back then.

Thank you.

That’s what they are imagining, and there are some doubts about this video.

I’m really tired, let me have dinner first. :)

If I discuss something with people too fiercely, it will be very hard for me to fall into sleep.

I’ll reply tomorrow.

Have a good day, all guys!

Nicely done. I was loathe to post a pic since Wenbin would not understand a still.

They did. We were there when it happened. Were you?

Wenbin Zhao said:
I trust they can land on the moon, but they can’t come back to earth ever, at least for now, let alone nearly 56 years ago.

What makes you think they couldn't come back?

You do realize that they have come back - several of them are still alive (here, on Earth):
Buzz Aldrin, David Scott, Charles Duke, and Harrison Schmitt.

OK. So there's a still two questions left.

1. How do you know physics is reliable? Specifically, how do you know physics is reliable? What physics have you studied? I thought you didn't trust any scientist, any science organizations, any science journals or even Google?

2. What makes you think the moon astronauts didn't come back? As I pointed out, four of them are still alive, and (notably) here on Earth.
