Thank you very much for the recommendation of papers, I will read it. On the question of hawking radiation needs/not horizon, my viewpoint is that: hawking radiation is a result but not a mechanism. This result says that the fixed position observers can measure particles from the vacuum defined...
I notified in the paper after eq(17) that `` where PC-diagram with different length of zigzag part denotes different size black holes and their corresponding radiation products''. So the Penrose diagram in eq(16) is not the usual diagram you understood denoting an evolving space-time.
The actual publication pages is as follows:

Another point which I wish to add here is, it's more appropriate to say "I myself believe it's the...
Dear everyone, I wish to discuss in this thread a classic/semi-classic interpretation on the origin of Bekenstein-Hawking entropy and the related resolution to Hawking's information missing puzzle, which were published in Nucl.Phys.B977 (2022) 115722 and Nucl.Phys.B990 (2023) 116171 after...
Currently, I did no numerical simulations about the gravitational waves following from binary black holes with non-trivial inner mass distribution. But I indeed read most of the existing literatures studying this subject. All of them seem to take the inner part of merging black holes as simple...
My key observation is, to reveal more in the further collapse after the schwarzschild radius is reached, the usual general relativity and canonical quantum gravitation may be enough.
To see this clearly, we only need to know a fact that, the very large black holes have very small average mass...
Dear All Gravitinos,
I write this post here to discuss a new conjecture on resolutions of the schwarzschild singularity and the physics interpretation for the micro states of black-holes (arxiv: 1606.06178, published in Nucl. Phys. B2017,02,005...
Dear All Gravitinos,
It seems that the current string theory and loop gravity's explanation for the micro-states of black
holes are all quantum mechanical and have no classic correspondence. I, in this day's arxiv, post a
pure classic interpretation for this question, titled "Black...
Dear every Mathematino-s in high energy physics
I knew several workers in computer and mathematics, but few of them know wolfram mathematica software, so I think it is justified to let my question appear here.
I use wolfram-mathematica to make 3D figures and want to use them...
Dear every specialists, I heard that BICEP2's observation r=A_t/A_s=0.2 n_t=0 indicate two things:
1) n_t=0 excludes ekpyrotic cosmological model (ECM) definitely because ECM predicts n_t=2
2) r=0.2 excludes almost all current string inflation model (SIM) such as KKLMMT because this...
Dear All Friends,
I am currently working on a project which needs some orthogonality
integration formulae of Laguerre polynomials. I referred worlfram's math
function site
http://functions.wolfram.com/Polynomials/LaguerreL3/21/02/01/
and get three seemingly useful ones...
More precisely, my question is, Is the wilson loop used to calculate the heavy quark potential always positive in the lattice simulation?

the heavy quark potentials

Dear Everybody,
I need some some function f(r) with asymptotics
as x -> 0, f-> 1*x+a*x^3+b*x^5+c*x^7+..., a,b,c>0
as x -> infinity, f-> x*Log[x]
I construct one like A/B*Log[1+x], where A=1+x/2+x^3/12, B=1+d*x^2.
But I think it is too complex, such that I cannot...
