Even if a probe were in a stable orbit near a black hole, we would still observe its signals redshifted by the gravitational field of the black hole.

Question

Quizplus · Accepted Answer

The gravitational field of a black hole is so strong that it causes the wavelength of electromagnetic radiation, such as radio signals from a probe, to stretch out or redshift as they escape the black hole's vicinity, making this observation correct regardless of the probe's stable orbit.

Even If a Probe Were in a Stable Orbit near a Black
