For the gravitational wave background, maybe with LISA we might be able to get a glimpse, but the neutrino background seems like it'd take some truly unprecedented breakthroughs in our ability to detect neutrinos to have any chance of mapping it out.

Funny, in reading up on both, I had higher hopes for the gravitational waves.

It seems like GWB is a superposition of infinite overlapping waves that would be impossible to single out and "unwind" in order to form a map.

And big bang neutrinos are very weak, which makes them undetectable. My assumption was we'd need a breakthrough in measurement sensitivity but is there more to it?

Naive thought - can a subsurface detector on the moon serve as an ultracold shielded scenario?
