I say, that the system will reach an energetic equilibrium at a specific frequency of resonance and from that moment energy level in the system will remain constant -
However, there are other ways to trap EM radiation at a specific frequency within the cavity - e.g. microwaves inside the owen. For practical reasons, this mechanism can be used, to test my claims experimentally.
Photons are made of Riemann-half-sphere-half-antispheres, with momentum encoded into it by added points of space. An antisphere is a sphere made of left out points of space.

No it is not.And this is not evidence for it.

You charge up the light absorbing inner surface with a tuned LED, and then pull the light source. The inner surface will emit photons, which are then absorbed, then reemitted, etc.
SideNote - Sorry We had that Irreligious scuffle in that Other OP, Unfortunate!✌️I Apologize for suggesting You to modify/change your NickName.🙏I Do Not Appreciate Unsolicited suggestions, advice or Information.👍Science, Religion or Otherwise.P.S. - Please do Not let this little sidenote distract You, & Please do carry on with the illuminating discussions.🙂& Yaa, i Really like Images that you post.👍Visualization makes it Alot more easier for Me to understand & absorb concepts.👌Nice Work!
When EM field inside the cavity is resonating in an unison frequency, those vibrations are transferred to the whole system, so, we'll end up with vibrations of the entire sphere - energy of EM radiation will then turn into kinetic energy of the whole system...
- I'd have to look for some info regarding this subject...

If this, what Bored Chemist claims is true, then we should expect, that the cavity will explode due to the internal pressure of emitted energy

Why do you think there is a difference between EM radiation and EM radiation?

Only in your model of radiation, this pressure should grow together with the increasing number of photons inside the cavity, until it won't blow up (because the material of cavity is too weak, to allow a black hole formation inside it)...
but you keep treating it, like increasing frequency.
If you completely isolate a source of heat with the temperature of 1000°C, temperature of a medium won't grow beyond 1000°C despite the constant radiation of heat.
What defines the energy of EM radiation?
It's because the difference of the wavelenght/frequency of EM radiation.

Don't insult me by linking my name to it.You see, I'm quite clever, so I can tell the difference between a cylinder and a sphere.I can see that the light will spill out of the sides of the laser if it can't get out of the ends.But you seem not to be well enough versed in science to realise that.Which is why you should stop posting tosh and go and learn some science.

Only you hallucinated that it might.But, in the scenario you described, there is a constant addition of energy via a (hypothetical) one way valve.
So, according to you what makes the most important difference here, is the geometry of cavity?
And what is the only difference between light and heat?
Let me help you - it's the growing magnitude/intensity of waves...
like increasing frequency.

NoWhat makes the difference is the big holes in the side of the cavity.
The difference is that heat is the microscopic mechanical energy of a substance- the movement of the atoms etc and can be transferred by conduction, radiation, convection or advection, but light is EM radiation within a range of wavelengths - about 400 to 700 nm.Again; from the fact that you had to ask that, it's clear that you don't know the basic science.
