The short answer is “I don’t know”. But they certainly seem to see structures in E8 that remind them of structures they see in the physics of elementary particles. My best guess is that these are mirages, and that behind it all is the representation theory of the binary icosahedral group (i.e., the double cover of Alt(5)), linked to E8 via the McKay correspondence.
