← ScienceWhich consequence results when gravity stresses adaptive optics?
A)Loss of guide star signal
B)Increased atmospheric turbulence compensation
C)Instrument-induced spherical aberration emerges✓
D)Improved point spread function uniformity
💡 Explanation
Gravitational bending causes *spacetime curvature*, deforming the telescope optics. This introduces wavefront errors because of the changed refractive index across the lens, therefore, spherical aberration is introduced, rather than atmospheric compensation or increased signal.
