Detecting Crossing Event Horizon w/ "Closed Box" Experiment

[QUOTE="Ibix, post: 6078789, member: 365269"] Indeed - I'm aware that I'm attempting to detect the failure of that assumption. I just wondered if there's an obvious reason it wouldn't work. You might be right - [URL='https://www.physicsforums.com/threads/how-far-from-event-horizon-are-you-safe.771596/#post-4857627']this old post[/URL] quotes an "ouch radius" with a 1g difference over a 2m human which implies the ouch radius equals the Schwarzschild radius for a hole of mass around [S]10[SUP]25[/SUP]kg, only slightly larger than the mass of the Earth, let alone a stellar black hole[/S]. Edit: ##c^3/G\sqrt g##≈10[SUP]35[/SUP]kg, or about 50,000 solar masses, still a smallish black hole. I really must double check my mental arithmetic. Sure - I was leaving open the possibility I didn't know the correct zeroing for my clock for some reason. I've left my notes at home but I think there were a few ##R_S## not attached to an ##R_u##. I'll have a look. [/QUOTE]
