abstract

We show how a modified Friedmann equation, originating from a model of the universe built from a certain $W_3$ algebra, has the potential to explain the difference between the Hubble constants extracted from CMB data and from supernova data.

A Jordan-algebra W3 model knits one-dimensional universes via wormholes into a 4D spacetime; a singular point of its modified Friedmann equation is claimed to explain the hierarchy and the small coupling g.
