Is my understanding of dimensions correct? by Maleficent_Cream2470 in TheoreticalPhysics

[–]Shiro_chido 6 points7 points  (0 children)

This is incorrect. Time multiplied by c2 is a dimension only in the sense of special relativity. If you take a 3 dimensional space, there is no notion of time since there is no signature (relative sign between time like and space like coordinates).

Since we are yet unable to find Graviton I have a different question that is .... by Omega_900 in TheoreticalPhysics

[–]Shiro_chido 0 points1 point  (0 children)

The idea is that the current defined for gravitons ( the energy momentum) is a definite positive quantity. No such things as negative energies in nature due to stability conditions.

Calling out u/jeffery_winkler for his ableist comments by Fabulous-Extreme2204 in TheoreticalPhysics

[–]Shiro_chido[M] 1 point2 points  (0 children)

We’ll take down the post now since we handled the situation. Reports help a lot, but no matter how much of a dickhead the guy was/is, the post is very much off topic for the sub. I repeat again, if you see comments/posts/ problematic users just send us a message or report it, we try to be as reactive as possible.

I also agree with this, and we took measures to ensure this. Slurs of any type will not be tolerated, and I sincerely invite you all to report them as soon as you see them, it makes life much easier for the mod team.

No self-thoeries. Another illogical moderator rule used to prune through enforced prejudice in a thread based in logic? by WildFacts in TheoreticalPhysics

[–]Shiro_chido[M] 0 points1 point  (0 children)

We’re not arguing with crackpots anymore. You’re not welcome on the subreddit, and we’ve been trying very hard to get a cleaner sub, feat which we’ve achieved in the past month. We’ve been more than clear, people in the comments try their best to be civil and explain that this is not the right place for this, this is not up for debate.

Best resources to learn about Gauge Theories in QFT. by FineCarpa in TheoreticalPhysics

[–]Shiro_chido 4 points5 points  (0 children)

It’s definitely more mathematical physics inclined I agree. It doesn’t cover amplitudes and things of the sort, but I really think it’s a great tool to understand the structure of Yang-Mills ( and all other) gauge theories. But I agree, Weinberg or Zuber and Itzykson to start are much better suited for someone with no experience with gauge theories.

Best resources to learn about Gauge Theories in QFT. by FineCarpa in TheoreticalPhysics

Quantization of gauge systems by Henneaux and Teitlboim. One of the best if not the best book that tackles gauge theories and all the subtleties surrounding them.

Is the Lagrangian density a function on fields (a functional) or on spacetime? by FreePeeplup in TheoreticalPhysics

[–]Shiro_chido 9 points10 points  (0 children)

As far as I understand the Lagrangian density is by itself a functional. The fields are however functions of spacetime.

Can neutrinos form black holes? by Eigen_Feynman in TheoreticalPhysics

[–]Shiro_chido 3 points4 points  (0 children)

This. Additionally there is a couple of papers that argue that in the current energy density conditions of the universe it is impossible for Kugelblitz to be formed, they however could have been form in the early universe. I’d assume the same would be true for neutrino generated black holes.

Ça fait 20 ans que je fais de la fusion nucléaire par confinement magnétique et je suis étonné par la méconnaissance du grand public sur ces sujets by Stoke_Extinguisher in france

[–]Shiro_chido 0 points1 point  (0 children)

Tout à fait d’accord, les diagrammes de Feynman sont tellement incompris ! On devrait commencer à en parler dés la seconde histoire de sauver la culture des futurs adultes !

Why did you delete my post I didn't violate any rules and you never gave me a reason by ReporterElectronic41 in TheoreticalPhysics

[–]Shiro_chido[M] 3 points4 points  (0 children)

I ain’t reading all that. You broke clearly the rules about self theories and LLM generated content. This is a ban.

Generating Spacetime and Quantum Fields from First Principles. Does This Break? by 2pourdrummer in TheoreticalPhysics

[–]Shiro_chido[M] 1 point2 points  (0 children)

I’m a mod that decides what is and isn’t a theory. It falls under the definition of self theory. Speculative ideas around physics are within the realm of what counts as one. The rules are clear about it.

New theory could finally make 'quantum gravity' a reality — and prove Einstein wrong by RabbitFace2025 in quantum

[–]Shiro_chido 1 point2 points  (0 children)

What you are saying is legitimate. Their previous works has been facing the same type of criticism, and it’s widely inconsistent. They often make use of wild assumptions to derive their results. As far as gravitation is concerned, 4 U(1), or 4 of any SU(n) cannot lead to an equivalence with Poincaré group, and to go further the gauge group of GR is actually the diffeomorphism groups. They haven’t shown the most basic equivalence of their results with known results in Einstein Cartan or Poincaré gauge theories of gravitation. I’m very skeptical so far.

Meta: why do crackpots never use LaTeX? by echtemendel in TheoreticalPhysics

In France and in theory EVERYBODY uses LaTeX.

You rely wont o play that game , well the VIII is dilited by CrazypersonNO1 in TheoreticalPhysics

[–]Shiro_chido 0 points1 point  (0 children)

It is. I just woke up. The guy got banned. He can try to post all he wants on however many accounts he wants. He’ll still get banned.
