Ancient neutrinos could put string theory and quantum loop gravity to the test

Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scalesMust the Schrodinger's Cat be fat enough for us to detect the possible phenomenon of gravity-driven collapse of the wave-function? In the 1950s, Feynman suggested that the infamous Schrodinger's Cat paradox would be resolved if gravity can be implicated for the collapse of the wave-function.
