I asked o1-preview a couple times, it gave me: *Answer:* Approximately 27 trillion kilograms—the black hole would need about 2.7 × 10¹³ kg of mass to exert tidal forces strong enough at 1 meter to tear off an arm. - This radius is much smaller than an atomic nucleus, so at a distance of 1 meter, the person is far outside the event horizon. No, the black hole with a mass of approximately \( 2.7 \times 10^{13} \) kilograms would not evaporate quickly due to Hawking radiation. Even though this mass is relatively small compared to stellar black holes, such a black hole would have an extremely long evaporation time—*on the order of \( 5 \times 10^{16} \) years, which is about 50 quadrillion years*. This duration is vastly longer than the current age of the universe, which is approximately \( 13.8 \times 10^{9} \) years (13.8 billion years).
