    A What does the equation C = 12 J mean for black holes?

    Do you have an opinion on the origin or significance of the coefficient 12 ?

    A What does the equation C = 12 J mean for black holes?

    Thank you Doctor D. That is the kind of Feynman-like simplification I've been asking for. I also appreciate Ibix and PeterDonis addressing the significance (or non-significance) and origin of the coefficient 12. A humbling, but useful, experience for a guy in need of more "maths" to...

    A What does the equation C = 12 J mean for black holes?

    I've read recently some measurements or approximations have indicted that some black holes rotate at nearly the speed of light, they say for example NGC 1365 is turning at 84% the speed of light…. Thus it's reasonable to speculate that matter drawn into the hole does at least approach the...

    A What does the equation C = 12 J mean for black holes?

    In Feynman style, might you be able to simplify for lay persons the general nature of this proposed resolution? Does it show, for example, some relationship between surface area of event horizon and entropy as Ibix suggests. Any other ways to help non-quantum physicists conceptualize...

    A What does the equation C = 12 J mean for black holes?

    Hawking prompts his team (six months or so before his death) with "How many conformal killing vectors on the two sphere. An infinite number?" The team guesses at first (3)? Then (6) perhaps? Hawking also asks "Would diffeomorphism give all the entropy?"

    A What does the equation C = 12 J mean for black holes?

    The documentary's focus is more on the first image of a black hole in 2018 or so but delves into Hawking's work on the paradox up to his death. Here is documentary : https://www.netflix.com/title/81343342

    A What does the equation C = 12 J mean for black holes?

    Just saw a documentary about resolving Hawking's "information paradox". In my own lay terms the physicists appear to theorize resolving the paradox with with their proposed C = 12 J . C is the central charge (which I don't fully understand) and J is the total angular momentum of the black...

    B Beginner Question Regarding Entanglement

    You have all been generously helpful with intuitive lay explanations (to the degree possible) and guidance to new contemplations for me, e.g. Bell theorem, uncertainty principle, locality, Counterfactual definiteness (wow), no-conspiracy -- some of which I've gained vague understanding in last...

    Much thanks--will do.

    B Beginner Question Regarding Entanglement

    As another beginner, I'll follow recommended reading as noted above--thank you. Nevertheless I'd like to ask the following: What is the experimental proof that attributes (like spin for example) of entangled particles are not pre-existing and inherent within the information of the particles'...
