Question dedicated to the memory of Steven Weinberg, whose books I read as a child and undergraduated student!
Beyond using gravitational waves, are out there any other ideas or proposals to detect the relic graviton background with $T\leq 0.9K$?

Why are you excluding gravitational waves? – TimRias Aug 11 '21 at 11:48

I am not excluding them, I only want to know if there are alternative probes to relic gravitons BEYOND gravitational waves... – riemannium Aug 11 '21 at 12:59

So you want to know if there probes for gravitational waves other than gravitational waves? – TimRias Aug 11 '21 at 13:11

As I mentioned here, we may never have the technology to detect single gravitons. – PM 2Ring Aug 11 '21 at 13:18

So are you think about things like detecting the GW background using polarization of the CMB (like BICEP2 originally claimed)? – TimRias Aug 12 '21 at 14:12
