This may present a challenge to our application of general relativity to cosmology. <br>\nSuch tensions are expected in quantum cosmology, wherein de Sitter space is unstable by dark energy from the cosmological <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 $[0,z_{\\max}]$. Independent of Planck, Pantheon data over $0<z_{\\max}\\le2.26$ are found to exclude $\\Lambda$CDM by <br>\n$4.3\\sigma$. In quantum cosmology, this reduces to $2.5\\sigma$.
