← ScienceWhich consequence most directly expands observed spacetime when approaching a black hole?
A)Increased gravitational light wavelength shifting✓
B)Increased Hawking radiation particle emission
C)Uniform tidal force material spaghettification
D)Event horizon thermodynamic entropy reduction
💡 Explanation
Gravitational time dilation causes increased observed *light* wavelengths because of extreme spacetime curvature near the event horizon; therefore, wavelengths are significantly expanded. This spectral redshift grows exponentially, rather than constant tidal forces on infalling matter.
