Abstract
abs: This essay outlines a number of developments in physics that together permit an estimate of the cosmological constant. Through an examination of strings which enter a black hole, and connections to the Jordan exceptional algebra, are shown to exhibit properties similar to graphene and systems with quantum criticality. This permits an estimate of a renormalized cosmological constant due to quantum criticality. addend: This paper is a survey of a number of developments which linked together could lead to a better understanding of fine tuning. The quantum criticality may also bridge some physics between string theory and Loop quantum gravity. This paper is to be followed by a supplementary paper which a reader may access. This paper illustrates more completely the mathematical details behind this general essay. Notice and its website will be given on my personal essay FQXI blogsite. This paper is intended as one step in a general program to find an underlying structure to string/M-theory according to quantum error correction codes. This work illustrates aspect of the Jordan exceptional algebra, which is a step towards understanding a universal quantum error correction code for quantum gravity and cosmology.
