Which observable result confirms the equivalence principle within black hole event horizons?

💡 Explanation

Extreme tidal forces confirm the equivalence principle because objects experience gravitational acceleration indistinguishable from acceleration in flat spacetime (freefall); therefore differential gravity becomes apparent, rather than singularity changes or quantum processes like Hawking radiation influencing observed effects.
