Which effect occurs at LIGO when a massive astrophysical object orbits its central black hole?

A)Spacetime distortion shifts the frequency
B)Thermal radiation eclipses gravitational waves
C)Quantum entanglement disrupts signal coherence
D)Doppler effect masks chirp signature

💡 Explanation

Spacetime distortion shifts the frequency, because the Extreme Mass Ratio Inspirals (EMRIs) cause mass-energy equivalence to manifest as gravitational waves that locally alter the spacetime fabric according to general relativity; therefore, the frequency shifts, rather than thermal or quantum effects, are the dominant influence.
