There is a somewhat recent theory that supports this idea. It is unclear whether or not things actually fall-in, but the idea is that the entire surface is a hologram, and the surface alone is sufficient to describe the entire contents. (Thus preventing any information loss). Much better described here: [VIDEO]

Not sure if it's related but this lecture gave me some basic grasp on the notion of holographic representations [VIDEO]

Suskind actually has a whole lecture on Youtube devoted to addressing the paradox of falling into a black hole from the perspective of the person falling in versus an outside observer. The outside observer sees the falling observer catastrophically turned into high-entropy soup smeared across the horizon, while the one falling feels nothing particularly special as they cross the event horizon.
