How does it rain on black holes?

From the perspective of a raindrop, how would it “percive” falling into a black hole? For super large/massive black holes, it’s said that there is “no drama”. The raindrop should experience it’s surroundings as if it was in empty space. The fact is, even though the black hole is warping space, it’s a vaccuum solution to Einstein’s field equations. Let’s lay some ground rules for what we mean by a raindrop....

About Scales

I was watching a Veritasium video. It was about the misconception of energy flow in electricity. The main take away was that energy flows fields. Classically, this is the Poynting vector. The energy and all that is important in electro-magnetism is through the electro-magnetic fields. Clearly, in the video, Dereck, demostrates that the the light is turned on wirelessly. The initial turn of the switch causes a change in the electro-magnetic field in which propogates the energy to light, causing it to “turn on” 1....
