Summary:: In the past I have been counseled to avoid speculation. Where can "edgy" physics discussions be held? In the past I have been counseled to avoid speculation. Where can "edgy" physics discussions be held? In my opinion, it is advantageous for physics and physicists to speculate on...

I was an IT manager at 3M before retiring. I am very, very good at hand waving.

Thanks. Rumination will continue however. More is learned from dead ends than the science community often recognizes -- and this DOES NOT diminish from your advise. I need to better understand the WHYs.

Thanks, Ibix, for your recent reply! This is something I can work with. However, being slow-witted, it usually takes me a number of weeks of contemplation sitting cross-legged to understand and move forward. With thumbs and forefingers touching one another, my rumination will cover at least...

In my opinion, the problem with this diagram is that only antiparticles are shown to be drawn into the black hole. If this were the case, naturally there would be a net loss of mass as the particles exit as Hawking Radiation. I should have included this diagram in my initial post. Unless...

My initial reaction to Ibix was incorrect, albeit for communication issues not substantive issues. Scientific knowledge is best served when point and counterpoint are aired without prejudice. Scientific work cannot prove something to be "right", only that it conforms to experimentation. Since...

More responses would be a big plus. Please move it down one notch, and thank you!

This is a discussion forum, not a game of whack-a-mole. Considerations about the subtleties of the English language aside, I have several questions. First, if the phenomenon occurs near but not at the event horizon, how is the phenomenon different from any other point in space where a quantum...

Does Hawking radiation at the event horizon of a black hole result in the reduction of the mass of the black hole? Quantum mechanics requires the creation and destruction of particle-antiparticle pairs throughout space-time. When this effect occurs at the event horizon of a black hole...

I have contemplated this reply for a number of weeks. While your followup provides a different response more in line with my thinking, this reply created a distinctly negative impression of your mentoring. What was the motivation for your thoughts at the time?

Given that a quasar is a super massive black hole with an accretion disk rotating at some significant percentage of the speed of light, what is the mechanism that generates the enormously luminous jet that emanates from the "poles" of the black hole that has become a quasar? a. The magnetic...

Perhaps: I just realized that the "area" described by x-t might best be described by "vector". I have to go have a nap and think about Vanhees71's suggestion, which certainly has merit. Interesting discussion -- the nomenclature will be different for physicists and for lay people if we pursue...

I might volunteer "frame". It is sort of in common use for 4-dimension curvature is it not?

1. Area is the naming convention assigned to that which is within a closed diagram in the x-y dimensions. 2. Area is also the naming convention used in simplified Lorentzian diagrams in the x-t dimensions. 3. Volume is the naming convention used to that which is within a closed vessel in the...

Yes, the website you mentioned was interesting. GP-B was a fascinating experiment, with the design of, the protection of from outside forces, and the measurement of results ingenious. Thank you for the reference.
