How can "torus shape" planet be "non-mainstream" physics?

Demanding that questions only deal with situations that unequivocally can occur in the real world rules out objects on infinite planes, point masses, Einsteinian trains, Maxwell's demon, supersymmetry,...

Flagging low quality answers: an experiment

I heartily support Emilio's proposal, but to explain why I support it will require a bit of rambling. So please bear with me and I'll try not to make this too painful. The Physics Stack Exchange has ...

Are the implications of magic on-topic?

No, questions involving magical situations are not generally on topic here. Our help center lists "questions about fictional physics" as one of the off-topic categories. The reason is basically what ...

Crackpots and links to crackpot articles in their profile

Is this OK with you, having reputable physicists (like Cosmas Zachos and Valter Moretti or Urs Schreiber to name a few) alongside crackpots? That's the wrong question. Let's suppose I'm not "OK" with ...

Why is the 'Physics' Stack Exchange site closing some interesting questions?

Well... to put it delicately, these are not anywhere near the mainstream. To put it less delicately, these are nutty questions. This site is not the place to entertain this kind of unfounded ...

How is this question about a black hole passing through the solar system non-mainstream?

I for one think the question is unclear or too broad. “Inhabitable” is not really defined, and actually hard to define. One can imagine the surface of the Earth is cold but that doesn’t make it ...

Why has my answer to whether the fine structure constant been deleted?

That was me. Out of concern that I might be prejudiced, I did some research before I removed your answer. Our policy about mainstream physics says, in part, What defines mainstream physics? ...

Why can't I ask hypothetical questions?

Is new physics a bad fit for Stack Exchange?

Technically, this site is not a forum; it's a Q&A site. It's not for generating conversation at all, it's for questions and answers to those questions. So based on that alone, this sounds like the ...

Why was this question down voted and closed as non-mainstream?

It's all about phrasing: "How are accelerated frames treated in special relativity?" is a perfectly fine question. "Special relativity cannot work with accelerated frames! Prove me (or &...

Reserving the use of the 'non-mainstream' close reason

I think you may be right. I'm not sure the scope of the close reason is meant to be quite as narrow as (it sounds like) you're proposing here, but it is good to be careful not to overuse it. We have ...

How is my question off topic when I'm asking what would be the outcome of a particular experiment and what would the results mean?
