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