- Black holes Holes
When I was a child, I was taught by engineers and scientists who had read physics papers in German and certain math and electronics papers in French. English translations for Americans contained many assumptions, misunderstandings and errors. My dad's old science textbooks written in English often contained untranslated sections in European languages that the student was assumed to understand. To this day I am still learning what some old textbooks actually meant.In summary, French speaking scientists objected to the term 'black hole' because it is undignified.f

Because whenever new light is shed on them, it immediately disappears behind the horizon!

Many physicists are satisfied with a Kerrsory understanding.

It actually started off as a serious question by @DaveC426913 but his post #1 somehow disappeared

I do not recall this. Are you suggesting I started this thread? No. I would have been more descriptive with my subject line.

Huh. Maybe I'm having a senior moment but I could have sworn the original post was yours. Guess my memory isn't what it used to be *

Glaswegian joke:
Is that a black hole or a meringue?
You're right enough, it's a black hole!

No. It belongs in the "April 1 jokes" thread - wherever that thread is...

Rumor has it French speaking scientists objected to the term as undignified.

Heh, heh, I started one several years ago, here.
But the joke character would be lost if they were all put in an obviously-Apr1 thread.

Huh? Is that because they have a stronger cultural emphasis on bleaching?

Since it's no longer April fools day, how about another question?
What is the closest analogue to Quantum Particle?
https://www.quantamagazine.org/massive-black-holes-shown-to-act-like-quantum-particles-20220329/
"Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave."

Sadly, most physicists don’t Kerr.

My knowledge of French colloquialism being non-existent, the translation evoked a different body part.

Even rereading the thread several times, I still don't know what term exactly it is the French find undignified... Unless it's 'black hole'.

When I was a child, I was taught by engineers and scientists who had read physics papers in German and certain math and electronics papers in French. English translations for Americans contained many assumptions, misunderstandings and errors. My dad's old science textbooks written in English often contained untranslated sections in European languages that the student was assumed to understand. To this day I am still learning what some old textbooks actually meant.
In this context many jokes arose due to colloquial expressions. For instance, I think a lot of nonsense surrounding Albert Einstein 'quotations' arose from poor translations and outright jokes from colleagues. The OP retains a certain dignified Old World style in his textbooks IMO that I enjoy reading.
Hence, my use of the term 'undignified' when alluding to the 'black hole' naming kerfuffle. All in fun.
