Hi,(adsbygoogle = window.adsbygoogle || []).push({});

The explanation I have been given for why GR breaks down at the quantum level is that GR requires spacetime to be mathematically smooth, and quantum foam is 'un-smooth'. If this is correct, then is a reworking of GR in a mathematics that does not require 'smoothness' one possible solution to this problem? Or is this impossible/I have been mislead?

Thank you.
