Visible and Dark Groups of Spacetime

A remarkable correspondence exists between lattices generated by discrete Jordan algebras and symmetries of superstrings, strongly suggesting that all known superstring theories are related and descend from a more general theory related to the Conway–Sloane transhyperbolic group. Cartan tori has visible spaces and $G/H$ Cartan generators as dark builders of $G$ and determined by root lattices. $E_{10}$ is shown as the dark group of the visible (9 + 1) space time with the Lorentz group $O(9+1).$ Embedding of the higher exceptional groups will also be presented.
