  "abstract": "<p>Surveys of the Local Universe show a Hubble expansion significantly greater than $\\Lambda$CDM estimates from the Cosmic&nbsp;<br>\nMicrowave Background by Planck. This may present a challenge to our application of general relativity to cosmology.&nbsp;<br>\nSuch tensions are expected in quantum cosmology, wherein de Sitter space is unstable by dark energy from the cosmological&nbsp;<br>\nhorizon ${\\cal H}$. We report on a novel probe of late time cosmology in terms of matter density $\\omega_m$ estimated over inner intervals&nbsp;$[0,z_{\\max}]$. Independent of Planck, Pantheon data over $0&lt;z_{\\max}\\le2.26$ are found to exclude $\\Lambda$CDM by&nbsp;<br>\n$4.3\\sigma$. In quantum cosmology, this reduces to $2.5\\sigma$.
