Mass Transfer to Blackhole
This image is very strong in mind as I read Smolins discriptions of the thing?:)
Consider any physical system, made of anything at all- let us call it, The Thing. We require only that The Thing can be enclosed within a finite boundary, which we shall call the Screen(Figure39). We would like to know as much as possible about The Thing. But we cannot touch it directly-we are restrictied to making measurements of it on The Screen. We may send any kind of radiation we like through The Screen, and record what ever changes result The Screen. The Bekenstein bound says that there is a general limit to how many yes/no questions we can answer about The Thing by making observations through The Screen that surrounds it. The number must be less then one quarter the area of The Screen, in Planck units. What if we ask more questions? The principle tells us that either of two things must happen. Either the area of the screen will increase, as a result of doing an experiment that ask questions beyond the limit; or the experiments we do that go beyond the limit will erase or invalidate, the answers to some of the previous questions. At no time can we know more about The thing than the limit, imposed by the area of the Screen.

How shall Gerard Hooft deal with this means of gathering information?
Perhaps Quantum Gravity can be Handled by thoroughly reconsidering Quantum Mechanics itself?
Quickly my mind wanders, to the experiments of Glast, and the gamma ray detection system. How will this informtaion allow such information, to align itself with quantum computer modelling and understand, what is hoped in gathering information from the screen?
No 'Quantum Computer' will ever be able to out perform a 'scaled up classical computer.'
