This may present a challenge to our application of general relativity to cosmology.&nbsp;<br> Such tensions are expected in quantum cosmology, wherein de Sitter space is unstable by dark energy from the cosmological&nbsp;<br> horizon ${\cal H}$. 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> $4.3\sigma$. In quantum cosmology, this reduces to $2.5\sigma$.
