The tidal stretching and compression of objects near the event horizon of a black hole (spaghettification) is a direct consequence of general relativity and gravitational field gradients, requiring no external citation.
The claim states a fundamental, textbook physical consequence of strong gravitational tidal forces near black holes (spaghettification). None of the retrieved papers specifically address or test spaghettification itself, as they focus on tidal disruption events (TDEs), gravitational waves, numerical relativity, and compact binary evolution. Since the phenomenon is a standard, direct deduction from gravitational physics, it is classified as common knowledge and requires no citation.
