Final Answer:
If a person were compressed to the size of a marble, it would not form a black hole. Instead, the matter would likely be crushed to an extreme density, potentially resulting in a state resembling degenerate matter.
Step-by-step explanation:
In this hypothetical scenario, as the person is compressed to the size of a marble, the matter would undergo an extraordinary transformation. The extreme compression would likely cause the atoms making up the person to reach incredibly high densities, possibly leading to a state of degenerate matter, where the normal rules of particle physics no longer apply.
While it may not form a black hole in the traditional sense, the outcome would involve a highly exotic and dense form of matter, challenging our understanding of physics.
Theoretical physics concepts like degenerate matter and extreme states of compression, exploring the boundaries of our understanding of matter under extreme conditions.
