Quote from: Bored chemist on Today at 08:42:55Quote from: Bored chemist on Yesterday at 22:31:50And you still seem to ignore the fact that , if a mirror hits a photon, momentum is transferred to the mirror.If the mirror was originally moving towards the photon, then the mirror will be slowed down by the momentum transfer.If the mirror is slowed down then it loses energy.And the conservation laws say that energy has to go somewhere.The only possibility is that it goes into the photon, and raises its energy.Where else?
Quote from: CrazyScientist on 14/06/2021 20:17:44Strange, I thought, that this is exactly what you said...No.What I said was that if you keep adding more and more EM radiation you will get a BH.Not, if you put a little light in a box and then wait which is what you sometimes seem to be talking about- for example when you say you heat something to red hot and then leave it in a box.Do you see the difference?
Strange, I thought, that this is exactly what you said...
Quote from: CrazyScientist on 14/06/2021 20:17:44It was never the question in this discussion...You introduced it in your opeingi postQuote from: CrazyScientist on 29/05/2021 02:31:39. If the sphere is somehow 100% indestructible, then energy inside it (density of photons) will become such high, that it will form a black hole - such hypothetical phenomenon has even it's own term, known as "kugelblitz".https://en.wikipedia.org/wiki/Kugelblitz_(astrophysics)Personally, I consider both those options as completely wrong and physically impossible.

There is nothing to stop the emission.
And here's what you can learn from it:The spontanoeus emission of an atom is not an intrinsic property, but depends on the atom's environment!I guess, that you'll tell now, that you knew about it all along
- and this is exactly, what something red hot in a box will do...
Quote from: CrazyScientist on 14/06/2021 20:17:44First you would have to prove, that it is even possible, to compress a bunch of photons into one photon,Nobody said anything about doing that.It is another of your tiresome strawmen.

Quote from: CrazyScientist on 14/06/2021 20:17:44What does it even has to do with the discussed subject?Because that's the mechanism for the mainstream science which you don't want to believe
What does it even has to do with the discussed subject?
Yes - because the question is: "what will happen due to constant EM radiation inside a perfectly reflective cavity?"
Quote from: CrazyScientist on 16/06/2021 11:41:24- and this is exactly, what something red hot in a box will do...NoIt will not.You seem determined to ignore the fact that a hot thing absorbs EM radiation just as well as it emits it.
Quote from: CrazyScientist on 16/06/2021 11:47:29Yes - because the question is: "what will happen due to constant EM radiation inside a perfectly reflective cavity?"Not much, but I did already answer the question; it depends on whether the walls are infinitely massive.If so, the light just bounces around forever.if not, the light gets thermalised.
Oh... So what exactly do you mean, when you're talkinkg about compressing a cavity, which is "full" of EM radiation to Shwarzchild radius? Doesn't it mean, to compress a bunch of photons into much less photons?
Maybe if instead of unconditionally believing in everything, what you hear from people with self-proclaimed authority, you would try to look for the answers by yourself, you wouldn't now make so many invalid statements...

So you didn't actually tell, that it will turn into a black hole, just like many other physicists would tell? Then what we were arguing about all this time?

Well, you can't be young forever, can you?

Doesn't it mean, to compress a bunch of photons into much less photons?Do you understand that if I say "you are full of s**t" it doesn't mean that all of your matter has been replaced, it's just a turn of phrase.You can't "fill" a space with photons because any single photon already fills the whole of space. That's how interference fringes work.So, you seem to be trying to say that it's impossible to have two photons in the visible universe.

Quote from: CrazyScientist on 16/06/2021 12:34:56So you didn't actually tell, that it will turn into a black hole, just like many other physicists would tell? Then what we were arguing about all this time?The interesting question.What happens if you make a mirror ball with a valve in which lets light in, but not out, and you shine a laser into it.The answer is that you get a black hole composed (almost) entirely of light.I say "almost" because the remains of the apparatus will fall into it.And the reason we are discussing it is that you raised it and said it was wrong.We also got into your weird belief that hitting a ball makes the bat go faster.And we may, one day, resolve your problem with accepting the conservation of energy.[Edit]I forgot to add that we might hope to address your hallucination that the "laser shining into a ball" experiment had been done- and hadn't worked.You may recall (or you may not) that you said it was experimentally disproven.
How can it absorb radiation at lower intensity, than the one which it produces?I don't say that a red hot thing can't get hotter - it can, but only when the temperature of it's surrounding will be higher than it's own temperature...
And, of course, notwithstanding your gish-gallop, you still need to address this.Quote from: Bored chemist on 14/06/2021 16:12:12Quote from: Bored chemist on Today at 08:42:55Quote from: Bored chemist on Yesterday at 22:31:50And you still seem to ignore the fact that , if a mirror hits a photon, momentum is transferred to the mirror.If the mirror was originally moving towards the photon, then the mirror will be slowed down by the momentum transfer.If the mirror is slowed down then it loses energy.And the conservation laws say that energy has to go somewhere.The only possibility is that it goes into the photon, and raises its energy.Where else?Your idea that the bat speeds up when it hits the ball is not one which the grown-ups will accept, even if it makes sense in your head.
Not really. According to the rules of Cavity QED, intensity of light inside the mirror ball will get so high, that it will become brighter than the incoming laser beam - and the intensity of light inside the ball will stop to grow.
And yes - it is experimentally proven, since lasers obviously don't turn into black holes...
May I ask, why do you speak to yourself?
