Sean Carroll, "Fluctuations in de Sitter Space" FQXi conference 2014 in Vieques
About | Information | History | Online | Facts | Discovery
fqxi.org The past century in physics seems to lead in a surprising direction: away from physics as a description of objects and their interactions, and towards physics as a description of the evolution of information. Is this the correct way to think about physics and the physical world? What is information? What does the term "information" even mean? What role does information play in quantum gravity, cosmology, thermodynamics, life and consciousness, and what links does it provide between these areas? FQXi's international, interdisciplinary conference on the Physics of Information brought together leading researchers to discuss the significance, meaning, and uses of information in physics.

Another excellent lecture by Sean Carroll.

everything is a measurement issue. one of the great talks. decoherence implies arrow of time.
-
classical versus quantum fluctuations. arrow of time in classical but not quantum state.

da fuq :-)

Evidently there's English within English that I don't speak :)
On the serious note, can someone explain what does this mathematical notation mean? |En><En| -
So what happens in anti- de Sitter space? And how can you just rule out a God hypothesis. i.e. a pre-existing consciousness.

ummm.... what??
sorry that was just my first reaction to listening to this
