    Hawking Spectrum
Click For Summary
Hawking radiation is characterized by a thermal spectrum, which allows for the assignment of a temperature to black holes, linking thermodynamics, quantum mechanics, and gravity. The discussion raises questions about the spectrum beyond photons, particularly regarding massive particles and their survival chances due to stronger gravitational effects. It suggests that the gravitational influence on massive particles could alter their spectral characteristics, potentially erasing the "red" part of their spectrum. This leads to considerations of how the spectrum of Hawking radiation may differ from that of a black body. Overall, the conversation emphasizes the complexities of understanding the spectrum of Hawking radiation and its implications in physics.

Simple questions. There is a formula for the POWER of Hawking radiation, but what's about it's spectrum? What is the shape of the power/wavelength curve?

Hawking radiation has a thermal spectrum, which is an amazing result allowing us to assign a temperature to a black hole. This is generally considered an amazing clue linking thermodynamics, quantum mechanics and gravity.
 
Yes... How I could forget about it... Shame on me...

Hm... What's about the spectrum of Hawking radiation other that photons? What's about massive particles? yes, their chances of "survival" are even smaller because gravitation affects them stronger as they are less relativistic. But it would "erase" the "red" part of their spectrum, making it different from the spectrum of black body?
 
"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
