Supportive if detected;
absence not exclusive
Casimir Energy
Gravitation
Vacuum energy gravitates as E/c² Long-term (10–20 yr) Clean falsifier if < E/c² at
≥3σ
Expansion History H(z) No kinks at QCD/EW/neutrino
thresholds
Near to medium-term Any kink → falsify CRF
Black Hole Echoes No horizon-scale echoes Now–2030s Echoes confirmed across
events → challenge CRF
