Abstract
The present note is concerned with two connected and highly important fundamental questions of physics and cosmology, namely if E8E8 Lie symmetry group describes the universe and where cosmic dark energy comes from. Furthermore, we reason following Wheeler, Hartle and Hawking that since the boundary of a boundary is an empty set which models the quantum wave of the cosmos, then it follows that dark energy is a fundamental physical phenomenon associated with the boundary of the holographic boundary. This leads directly to a clopen universe which is its own Penrose tiling-like multiverse with energy density in full agreement with COBE, WMAP and Type 1a supernova cosmic measurements.
Highlights
The exceptional E8 Lie symmetry group played a major role in condensed matter physics and developing various superstring theories as well as high energy physics
The present analysis shows once more the unity of theoretical physics and cosmology in a simple but impressive way [1]-[4]
Using E8E8 exceptional Lie symmetry group of superstring theory, an exact expression for the ordinary and dark components of the cosmic energy density are obtained which are in full agreement with measurements [1] [6]-[8]
Summary
The exceptional E8 Lie symmetry group played a major role in condensed matter physics and developing various superstring theories as well as high energy physics (see Ref. 1 and references therein). It was used for instance by the present author in quantum cosmology and in connection with the issue of dark energy [1]-[8]. (2014) Entanglement of E8E8 Exceptional Lie Symmetry Group Dark Energy, Einstein’s Maximal Total Energy and the Hartle-Hawking No Boundary Proposal as the Explanation for Dark Energy. We stress that our confidence in our explanation of dark energy [11][23] stems from its simplicity and agreement with Wheeler, Hartle and Hawking’s analysis but mainly from the agreement with the most recent accurate measurements [6]-[9] and observations [23]
