fsakura·3 年前·議論Why do you think the black box with the black hole will gain mass over time?AFAIK:On the contrary it will lose mass over time due to Hawking Radiation and evaporate eventually (though that might take literally forever).Also spacetime curvature will be slightly different for point mass vs distributed mass.
