What happens to objects falling to a black hole (from outside observer's perspective)?
There seem to be a consensus that because of time dilation, an object's fall towards event horizon will take a long, ever-stretching time. There seem to be no consensus regarding whether this fall will take finite or infinite amount of time, or, because the object will cease to be observable, the whole question is moot.
Consider the following scenario: There is a Schwarzschild black hole of 10 solar masses (event horizon radius of 29.5 km), and there is an object falling to it, which is close to the event horizon, nearly frozen because of time dilation, but the one that we STILL CAN observe. The black hole is growing over time from 10 to 20 solar masses, which causes its event horizon to increase to 59 km. What will happen to the falling object, from outside observer's perspective?
The object will cross the event horizon, and there can be some proof of it;
The object will cross the event horizon, but there never can be any proof;
The object would get "plastered" over the event horizon and pushed outside as it expands.
There is a number of questions here on physics SE discussing black hole origination and falling into it, but does not seem like any which discusses this particular scenario.
