Found that in a universe that is expanding after a big bang event, neutrinos would turn up at a detector before they were emitted. Only future-going neutrinos were possible in the Steady state cosmology while the ever-expanding big bang models gave neutrinos travelling into Steady State theory to the past.

If you see firm evidence of neutrinos arriving at the detector before they are sent, that can't happen in a Steady steady state cosmology, so the Big Bang has to be right. Or equivalently, no faster-than-light neutrinos, no big bang.

Jayant Narlikar

I have not been able to relate the idea to the 'faster than light' neutrinos since there are no causality checks to decide if they are travelling in the past.

Space-time in an expanding universe changes over time, so the full quantum description of a neutrino. in that type of universe is different in the past and the future. Neutrinos would behave in both expanding and unchanging "steady state" universes.
