No. I'm trying to say, that photons are the most fundamental "units of physical reality" and it's impossible, to make them smaller...

It's where the forward and backward reactions happen at the same rate.Imagine a (fireproof) ant sitting on the red hot thing.If he looks around all he sees is either the hot body under him, or the reflection of it in all other directions and, since it's a perfect mirror, the reflection looks identical.He just sees "red hot" all around himself.And so, he can't tell if he is in a 1000C oven or in a reflective shell.If he was in a 1000C oven than it's clear that the body would stay at 1000CAnd, as far as our ant can tell, he is in such an oven so the block does stay at 1000CIn practice this fact- the maintenance of temperature by reflective surroundings is used in pizza ovens and in this sort of thing.https://en.wikipedia.org/wiki/Reverberatory_furnace

When the density/intensity of EM field in the cavity reaches a specific "capacity" of probability distribution at the frequency of emitted EM waves, source of radiation becomes unable of further emission, until some part of the radiation won't be absorbed back from the system by the source - and then this quanta of EM energy radiates once more into the cavity, only to be absorbed back by the source (and this process is being repeated in a loop, until some external factor won't disturb the energy equilibrium of the system)

Yes; you are reminding me that you have a claim that something can't emit light.So what?In the version with a laser and a valve, there's nothing in the sphere to emit anything.So your "citation" can't be relevant.Why make it again?
Irrevelant you say... So you completely dismiss an entire branch of modern physics, because it is in disagreement with your old-school (and outdated) beliefs?
since lasers obviously don't turn into black holes...
You should read about such term as local density of states
But you will have to go beyond that limit, if you want to compress a macroscale EM field, which is made of photons, into a "tiny dot" of space...

Quote from: CrazyScientist on 16/06/2021 13:20:13You should read about such term as local density of statesI think you should look at the behaviour of bosons.

Problem is, that the number of standing EM waves inside a cavity
However, it's experimentally proven, that interactions between extremely energetic photons can lead to creation of matter in form of partiicle-antiparticle pairs of electrons and positrons, which are annihilating each other shortly after their "birth" and turn back into photons. I'm not sure, if such interactions have anything to do with gravity...
I've spent last couple days looking for some sources, that might have something in common with my idea of X-stationary photons with a constant nuber in some given volume of a photon field, but I wasn't too successful.
As you can see, frequency of a wave is here directly connected with the velocity of photon's vibrational (Y,Z oriented) motion
Problem is, that this is exactly the mechanism, which makes photons a time-finite packets of energy and leads to the idea of black hole made of trapped EM radiation.
EM radiation needs to be described in terms of probability distribution.
it will become quite obvious, that in the case of photoelectric effect, intensity of EM field will be related with the number of ejected electrons, while their kinetic energy will depend on the frequency of EM radiation...
Quote from: CrazyScientist on 19/06/2021 05:30:31Problem is, that the number of standing EM waves inside a cavityBut there is no requirement for the photons to form standing waves; they can just bounce about with random phases.In fact, they must do so,because the energy/ time version of the uncertainty principle says that the energy - and therefore the wavelength has an uncertainty.Because you are not sure what the wavelength is, you are not sure if it will allow a standing wave and, in the end, it won't.So we can discount standing waves from the discussion.
I presume that you know that this works both ways.A particle - e.g. a proton- flicks between that state and also being a pair of virtual photons.So any (un charged) black hole made from "conventional" matter is therefore also a part-time kugelblitz.
Well, I could have saved you a lot of trouble.A photon, by it's nature can not be stationary.You seem to have made up the idea of an "X-stationary photon" without saying what it means.But, if you only just invented it then clearly, your search won't find anything about it.Google gives just one hit for it, and that is this page.Nice Googlewhack, but making up words to do that is considered cheating.
Quote from: CrazyScientist on 19/06/2021 09:14:47As you can see, frequency of a wave is here directly connected with the velocity of photon's vibrational (Y,Z oriented) motionPlenty of real science shows that photons have angular momentum.So this idea of "up and down" as they travel along is untenable.It would get scrambled by the spin (yes, I know, electron and photon "spin" are not classical rotations, that's not the point. There's enough similarity to "screw" your idea.)
The other thing about the photoelectric effect is that the photon loses energy, so it's not a process which could be relevant to a perfectly mirrored ball.It's laughable that you thought I might not be aware of, and have considered the PE effect.
Quote from: CrazyScientist on 19/06/2021 09:14:47Problem is, that this is exactly the mechanism, which makes photons a time-finite packets of energy and leads to the idea of black hole made of trapped EM radiation.That is only a problem in your head.Everywhere else, it is recognised as a solution.Maybe you should think about that rather than posting obvious stuff about hundred year old physics which you don't understand.
