← ScienceWhich consequence arises from Einstein's equivalence when considering black hole event horizons?
A)Increased spaghettification near the singularity
B)Gravitational redshift of emitted photons✓
C)Unchanged photon escape across horizons
D)Hawking radiation ceases near horizon
💡 Explanation
Gravitational time dilation occurs because of the equivalence principle: acceleration and gravity warp spacetime; therefore, light escaping a black hole loses energy via gravitational redshift, rather than escaping unchanged because gravity’s effect on spacetime.
