This analysis explains the lack of light from LIGO's mass-gap objects, suggesting implications for gravitational wave research.
Description All confirmed LIGO-Virgo-KAGRA mass-gap events (GW190814, GW230529, O4 candidates) fall within the CCEGA intermediate regime (2.33–9.20 M☉, P36). These ultracompact horizonless objects are electromagnetically dark by construction — explaining the absence of EM counterparts in all cases. GW echo timescales of ~3–5 ms predicted for massive remnants, testable with Einstein Telescope. O5 provides first falsification opportunity. CCEGA Program Paper 37.
