As material flows into a black hole as viewed from well outside the event horizon

Question

Quizplus · Accepted Answer

As material flows into a black hole from an outside viewpoint, it will experience extreme gravitational redshift, causing time dilation. Additionally, the material will be compressed and heated to very high temperatures by the intense gravitational pull, leading to emission of X-rays and gamma rays. Therefore, the correct option is E as it includes both time dilation and material becoming hotter. Option A alone is not the best choice because it only mentions time dilation but doesn't account for the heating of the material. Option B alone is not the best choice either because the heating of material is not caused by direct external heating sources but by gravitational effects. Option C is not correct since absorption spectra are not produced in this scenario. Option D alone is not the best choice because the material will appear to fall into the black hole more slowly due to the time dilation effect.
