- Summary:
- Saw this formula on documentary about black holes. What does it mean … really mean ... in lay terms as much as possible.

Just saw a documentary about resolving Hawking's "information paradox". In my own lay terms the physicists appear to theorize resolving the paradox with with their proposed C = 12 J . C is the central charge (which I don't fully understand) and J is the total angular momentum of the black hole. 12 is an interesting and elegant coefficient (IMHO) having something to do with geometry, vectors and spheres … perhaps

In lay terms, the physicists seem to be saying that this simple formula demonstrates that the event horizon (EH) of a black hole has the capacity to absorb and retain information about all matter and energy that has fallen into the black hole by means of holding or releasing the information somehow through a quantum mechanism or structure called "soft hair" that radiates information out and away from the EH. Thus the information paradox could be resolved if C = 12 J is valid.

My question(s) are how does some value for total angular momentum relate to a capacity for a black hole system (through its soft hair) to preserve information? What is the central charge (in simple terms) in this context? Why 12 ??
