A neutrino modem would absolutely work because the technical issues could all be solved by capturing the traffic from the future and reverse-engineering it.

How would that work?

Even ignoring the almost negligible amount of mass a neutrino has, it's still limited to c meaning we aren't getting new information before anything else.

Neutrinos can totally go back in time. It's essential to the plot of "Watchmen" 2009 and that's as good as peer review. it's just not in physics because Einstein was a Marvel fan.

I'm pretty certain that was tachyons, not neutrinos...
