← ScienceWhich mechanism causes gravitational lensing around neutron stars?
A)Spacetime curvature following mass equivalence✓
B)Quantum entanglement creating virtual particles
C)Frame dragging accelerating photons locally
D)Doppler shift altering spectral wavelengths
💡 Explanation
Photons follow geodesics (shortest paths) in spacetime; mass-energy equivalence causes spacetime curvature by massive objects altering their paths through gravitational lensing. This is because spacetime is warped, therefore light bends around the neutron star rather than going straight; Doppler shifts affect frequency.
