Can there be quantum fluctuations within a singularity?

Hello,

 

Can there be quantum fluctuations within a singularity?

 

Thanks,

Well, a singularity by definition is a dimensionless point, so there isn't really a "within" for anything to happen in.

Then again quantum mechanics doesn't allow for dimensionless points as they would have infinite fluctuations in their energy/momentum.

Well, with classical gravitational singularities one would expect the quantum nature of space-time to regulate these. The fluctuating or granular nature of space and time may smear out these singularities. However, without a proper theory of quuantm gravity it is hard to say exactly what happens.

Thank all of you for your replies.
