I definitely appreciate the input. Good to get the synapses firing again after the infantry lowest-common-denominator homogenization. Thanks, John

Marcus, I am leaving active Army service in the next two months, after which I will complete my schooling, so I will indeed have access to university libraries. The kanji was chosen for a few reasons, including the death of an old way, and the beginning (or renewal) of a different path...

marcus, thanks for the in-depth and insightful reply. You did indeed understand exactly what I was asking. I'll have to get the book you reference, when I can (my life is pretty busy just now). You can check posting date and time at the bottom of the messages. Regards, John Shirley

Thanks for the responses. This is all theoretical, though, right? We can prove that something is refracting light in certain areas, but we can't actually "prove" a singularity? Because of the extreme forces involved, would be ever be able to prove what happened inside a singularity? John

I suppose I assumed black holes to be "dead", but I see what you mean.

I think I may have answered my own question- y'all let me know, if not. A "dark star" cannot exist, because the amount of gravity required would mean that the star was immensely dense, and stars cannot reach that level of density while nuclear reactions are still producing outward force. Right?

Would it be possible for a star to be so large that the light emitting from it was redshifted beyond detection? I had a question that I wanted to puzzle out in a research paper, but it seems easier to find questions than answers. Anyway, thanks in advance, John

Um, photons have no mass, do they? Forgive my ignorance, as this is all very new to me, but the definition of mass involves an object at rest, and photons are never at rest. Right? If we accept that, then must they also not have any gravitational attraction? I have the impression that...

Perhaps we're straying, but I can't say that I understand the whole "event horizon" flowing outward thing. At all. John

Uh, you mean, if the object was so massive, the gravitational pressure would be so high, the temperature would reach 108 K, and the outward radiation would keep pressures from rising further?

Thanks for the reply. I do understand that Newtonian theory believes light to be particles, and under-predicts the pull of gravity on light. So, according to current knowledge, a black hole is the only entity with gravitational attraction strong enough to capture light? Are "black...

First, let me thank you in advance for your patience. I understand there is a lot of foundation I need to build before I can truly learn much of what I need to know, and I thank you for your assistance. We know that gravity is strongest closest to large objects. Gravity seems to effect...
