Cosmic maps from large-scale surveys and the cosmic microwave background are consistent with a mechanism in which black holes convert one dark-sector substance into another. Computational calculations indicate that such a conversion can reproduce the observed cosmic expansion history and the clustering of matter across scales. The mechanism offers an unconventional origin for dark energy while modifying the local dark-matter distribution around compact objects. Predicted neutrino masses or interactions align more closely with measured neutrino properties than predictions from earlier dark-sector models. The mechanism predicts observational signatures in galaxy surveys, gravitational-wave events and neutrino experiments that can be used to test and constrain the proposal.
Cosmic maps appear consistent with the proposal that black holes could turn one 'dark' substance into the other.
An unorthodox explanation for dark energy fits with cosmological observations and better matches known properties of neutrinos than previous models do, calculations have shown.
