What are you asking? And how does your link relate to what you're asking? What do you mean by "cosmic censorship"? Are you asking if string theory allows for the existence of naked singularities?.... then ask that question. Please make it abundantly clear what you're asking, so we don't waste our time.

Nice tone! I actually *did* read the article and found it interesting, but the article does not state your confusion. I don't know if you expect me to read your mind? I don't understand how you have not figured out that you should be putting exactly the information you just provided to me but IN YOUR POST.

Does the combination of concepts of "cosmic sensorship" and "Gregory-Laflamme instability" correlate with the "string theory" since it appears that both require multidimensional spacetime structure of the universe?

The [cosmic censorship hypothesis](https://en.wikipedia.org/wiki/Cosmic_censorship_hypothesis) is a very general concept in general relativity that says nothing specific about the number of spacetime dimensions (though I would assume most discussions of assume a standard four-dimensional spacetime) and has nothing to do with string theory; indeed, it really predates the development of string theory itself.

The [Gregory-Laflamme instability](https://core.ac.uk/download/pdf/25350464.pdf), on the other hand, is directly based on string theory and *requires* more than four spacetime dimensions (10, for string theory).
