← ScienceWhich limitation arises due to spacetime curvature near orbiting pulsars?
A)Gravitational lensing distorts signal paths✓
B)Doppler shifts mimic pulsar wobble
C)Alfvén waves interfere signal arrival
D)Synchrotron radiation masks faint pulses
💡 Explanation
Gravitational lensing affects signals because mass causes spacetime curvature, deflecting light rays. Strong curvature near pulsars causes gravitational lensing effects altering signal propagation, therefore, distorting arrival times, rather than simple Doppler shifts due to the pulsars motion.
