In string theory, what replaces the black hole singularity?

I know that it is possible for a single string to have arbitrarily large energy. Is a black hole just a single string?

  • $\begingroup$ In the Maldacena thesis linked by anna v, there is some possibly relevant material on p. 59 and in figure 6 on p. 60, but I don't understand enough of the paper to know whether this is really relevant. $\endgroup$

  • $\begingroup$ I think the answer is something along the lines of "nobody really knows, but there are some interesting proposals"... $\endgroup$ Oct 29 '19 at 5:03
  • $\begingroup$ Do you mean by your suggestion that matter collapses into a single string? $\endgroup$

  • $\begingroup$ @Wookie I remember reading somewhere that because there are infinitely many string vibrational modes, it is possible for one string to have the entire energy of a black hole. Is this what actually happens? $\endgroup$

Fuzzball theory replaces the singularity at the heart of a black hole.

    $\begingroup$ Fuzzball theory is not standard string theory. Only a small fraction of string theorists accept fuzzball theory. $\endgroup$ Oct 20 '18 at 12:39

  • $\begingroup$ @Demi .I see that your opinion about my answer has changed.I think that maybe peter shor was right about its acceptance.If that's the reason please say so ,so that I will either delete or edit my answer. $\endgroup$ Oct 26 '18 at 16:19
