Hi!
There's got to be something wrong with the following method to take photographs of the area inside a supermassive black hole, but I can't figure it out.
1. Lower your spacecraft to just outside the event horizon.
2. Extend a uniform steel bar with cameras embedded in it through the event horizon. The bar's central of mass remains outside the event horizon.
3. Take a photograph from the cameras inside the event horizon.
4. Pull the steel bar back into your ship and take off.
The question is: if there's a flaw in this plan, it's got to be a situation where the bar breaks somewhere around the event horizon so that the part inside the horizon stays in.
Except for one thing. What would cause the bar to break? It can't be tides, because tides are minimal outside a supermassive black hole. Yes, in theory the stuff inside the black hole is going to be pulled in. However, this is ignoring the material strength (tensile strength or something like that -- I can't remember what it is) of the bar. You need a certain amount of stress on the bar to break it, and I'd expect that downward force by spacetime tugging the bar in could be overcome by the tensile strength of the bar.
What am I missing?
Thanks in advance,
