I know that the rubbersheet / fabric analogies that we see on TV and in various diagrams are only a metaphor, but I'm having difficulty getting started researching what we actually know / theorise about the make-up / workings of the "fabric"?(adsbygoogle = window.adsbygoogle || []).push({});

Could you give me any pointers to good postings, or even key words to search on, or good articles that discuss the workings of the fabric of spacetime?

Thanks in advance,

Noel.
