Finding E8 lattice root system links discrete spacetime to quantum gravity implications.

To explore the E8 root system as a potential discrete spacetime structure in the context of quantum gravity.
Analyzed E8 lattice characteristics including root dimensions, Coxeter number, and packing density in 8D.
Examined the mathematical relationships involving E8's Cartan matrix eigenvalues and ratios between roots.
E8 exhibits crystallographic symmetry with specific root angles and a packing density of approximately 0.2537.
The key ratio of 30/240 equals 0.125, linked to E8's Cartan matrix eigenvalues and not classic harmonic ratios.

Andrew Stewart Caldin (2026) studied this question.
