Good question. I suppose the answer depends on what studying relativity means in your questions. If it means obtaining an advanced degree in the area, the answer is that that degree of time and financial resource commitment would need to be for something I intend to do professionally, and I...

Agreed: it is not black and white, some sites do it better than others. Another way to avoid problems is to consider what you are reading as an assertion is actualy a question. I'm old-fashioned and like to use question marks for that purpose, but I'm totally open to using whatver works here...

It may not be what you are discussing, but it actually is at the core of what I'm trying to ask. Again, I may be committing the sin of not knowing how to articulate this. So.... shame on me?

The second sentence: "If black holes "evaporate" via Hawking radiation, then they cannot exist forever." It was intended to make clear that the scope of my question pertained to evaporating black holes.

The first point I made was what I think I would be observing, and is not proposing anything. The remaining 4 points I posted end with question marks, so it would be clear I was asking, not proposing something. How can questions be interpreted as proposing a resolution?

That makes sense. Next time I'll close my OP with something like, "I have no expertise in this area, so there may well be something basic I am just missing." So everyone knows I am seeking information rather than proposing a resolution... Oh, wait... well, that is exactly what I did say...

Well, good news: I was able to find someone who helped me find a fascinating paper on exactly what I was asking. I'm not an academic or professional, so I don't know the proper vernacular to articulate clearly what I am asking. Sorry if that offended anyone. I didn't think to talk about...

It is hard, if not impossible, to maintain an openness to learn anything when you sincerely ask someone where they are making a mistake, and the answer is essentially, "everywhere." I really tried not to take it personally and learn something, but the tone was so persistently insulting, it sort...

That would be the clever insult Dirac threw at a student who made a wild guess about the wavelength of visible light when he didn't know. The student guessed something quite large (a few feet if I recall), and Dirac cut back into him, "Am I blurry?" The crux of the insult is that the...

I'm here to be wrong and corrected, and offer my thanks in advance. Yes, I do have a confusion of ideas: when I think about this topic, there are ideas I have that don't make sense to me. I love to be wrong, and I want to have some degree of understanding where and how I am wrong. I'm sorry...

When I say disagree, I am only referring to observations made in different referance frames. I do not see a paradox in the differeing perspective of simultaniously, and non-simultaniously in there is no universal now. As I understand it, the only differation of...

Awesome - thank you. Please tell me how my premises are flawed, so I might learn. OK, I believe you. What are my specific background limitations you are referring to? I'm asking so I might know where I can improve them. I should not ask questions I don't already have a specific background...

I respectfully disagree: There is intrinsic value in looking at a flawed analogy for the purpose of figuring out why the analogy is flawed, provided you are open to corrected understanding.

Heh... I may have made conflicting claims. But honestly, I did not mean to make a claim. My understanding of spacetime and blackholes are is limited. That's why I felt compelled to find some way to ask about these concepts in a place where I might get answers from people who know.

Is that related to how, within a past/future spacetime diagram, you can take any perspective in the light cone and, with a geometric transformation - skew the diagram - and get the equivalent spacetime diagram with respect to any other perspective? My mathematical background only went up to...
