Imagine a hypothetical universe where the arrow of time is subjective based on the state of matter. Inorganic objects experience entropy in reverse, effectively un-eroding and returning to their original forms, while biological entities experience time linearly as we do. Describe a scenario where a human interacts with a reverse-aging object. Analyze the causal paradoxes that would arise if the human tries to manipulate the object. Discuss the thermodynamic laws that would need to exist to support such a reality.
