comment Does the holographic principle for black holes mean that information is cloned?
OK. And now I would suggest to the mods that they get rid of everything from that exchange except the first and second comments from CuriousOne, and the second one from me.

Let us continue this discussion in chat.

Anyway, I am MOVING THIS TO CHAT if you don't beat me to it.

comment Does the holographic principle for black holes mean that information is cloned?
But these debates are partly about what sort of theory is logically possible. That has consequences for what sort of ideas get considered...

There was no empirical issue but there was an issue of principle - whether quantum gravity respects unitarity.

The anyon questioner knew her subject so that was OK, but when you do this with a layperson, they will assume that your answer is correct and relevant within the framework of the theoretical conception they are asking about.

On both occasions, rather than lead with your real opinion - this (anyon math, quantum black holes) isn't real physics, instead you leap straight to an answer that is technical and somewhat off-topic.

So you do have "curiosity" after all. But you are at your worst when it's a theory question that you don't think is about real physics, if this question, and the recent anyon question, are any indication.

By a top-level question, I mean a question posed using this site's official Q&A mechanism, as opposed to a question asked in comments. I think I've seen you do the latter, especially when you think it is a real physical question.

But I will say - and I expect this comment to be deleted - that you have an extremely arrogant tone a lot of the time. You have apparently never asked a top-level question on this site; which is ironic given your alias.

I guess that, if you sincerely thought that the only issue here is a general one about the physical meaning of "information", I can't accuse you of being negligent or something.

This is a question about holographic duality and whether it implies a duplication of quantum information in violation of the no-cloning theorem.

"No, it doesn't say that." @CuriousOne, the tone of your reply is bad because you make it sound authoritative when in fact you miss the point of the question.

@HDE 226868 Actually, you don't know that. They may be related, they may not be.

comment What does it mean physically if pentagon identity or hexagon identity doesn't have any answers?
@CuriousOne the question is in the title. I interpret it as asking whether all solutions to the fusion rules must obey those identities.

comment What is the property of neutrino?
The spin and momentum of a particle are affected by other interactions too, Z boson and photon don't have a special role there.

comment Why do we need complex representations in Grand Unified Theories?
I am a bit puzzled about the relation between this argument and Edward's... is one more fundamental than the other. Further thought required.

comment Why do we need complex representations in Grand Unified Theories?
If $\psi$ is real, then a term of the form $m \psi^* \psi$ should automatically exist - whereas, if $\psi$ is complex, that term exists only if a separate, complex-conjugate field is part of the theory. And then I think naturalness is used to argue that the coefficient will be large enough to matter.
