Recently I have removed one question related with Topology and physics. This is the link, but is removed, I do not know if it could be seen by the administrators (here):
It was regarding a question in between Topology and Physics. Basically the question was: why there is a limit in the dimensions defined in the Superstring theory (11) when in the other hand in the Topology theory if we have a n-manifold then it implies (basically) the existence of a n+1-boundary, and that implies the existence of a n+1-manifold, so in theory if a 11-manifold is possible then a 12-boundary is possible, and a 12-manifold is possible. The part of the question related with Topology seemed to be accepted (as long as I can see in the comments) but today it was flagged to be closed as offtopic due to the part of the question related with Physics. I decided to close it myself before it was closed.
I am the first one interested in keeping my questions on topic, and if there is a tag named mathematical-physics if the question shows some effort and elaboration I do not know why it should be closed.
This is a collective so I see this as an opportunity to learn what is on topic and what is not. Is just that in this case I really wanted to know more about then question and though it would be legit to ask about it.
I would like to know how can I enhance that question or why is a bad example of mathematical-physics tag question.
p.s. this has happened to me only in this occasion! :) just would like to know what can be changed to make it on topic. Thank you!
