Here is a bit more on the video and what is discussed:

These renowned scientists discuss on a very distinguished panel the ideas, theory, scientific observation and experiments behind the fascinating, and sometimes surreal, study of black hole physics, entropy, quantum mechanics, entanglement and the holograms – all key areas in the physics of information theory.

This discussion was filmed at the Perimeter Institute for Theoretical Physics, an independent research center for the foundations of theoretical physics located in Waterloo, Ontario, Canada. The host of the debate is “Quirks and Quarks” radio host Mr. Bob McDonald.

One of the core properties of quantum entanglement is that observation of the material world that we think to be certain actually changes the outcome.
