This question already has an answer here:

In general, physics seems to consider elementary particles such as electrons to be point-like. On the other hand, naked singularities seem to cause all sorts of trouble, including closed time-like curves, and are generally considered to be non-physical.

What is the exact difference between a point-like particle (eg electron as we know it) and a naked singularity (eg black hole electron), and why exactly considering a particle point-like is ok, while considering it to be superextremal black hole is not?

  • $\begingroup$ I checked the questions linked above, and while relevant and interesting, they do not seem to explain why point particles do not have the same non-physicality issues as superextremal black holes. I am not sure how to address this in the question more precisely... $\endgroup$ – tuomas May 4 at 5:24
  • $\begingroup$ With naked singularities you loose predictability. No such problem with point particles. $\endgroup$ – MBN May 4 at 10:22
