Quantum Gravity at Planck Length

Posted on January 7, 2005 by PlatoHagel

It was necessary to bring some of this infomration here while things are getting sorted out elsewhere. 6.4 Spacetime Topology Change by Joseph Polchinski This subsection is not directly related to black holes, but deals with another exotic question in … Continue reading →

Catch a Wave From Space

Posted on December 17, 2004 by PlatoHagel

Imagine the journey it took for us to have come to the developement of the methods to discern the nature of the Universe, and what Einstein has done for us in terms of General Relativity. A statement, about Gravity. Imagine … Continue reading →

Quantum Microstates: Gas Molecules in the Presence of a Gravitational Field

Posted on December 4, 2004 by PlatoHagel

Andy Strominger: This was a field theory that lived on a circle, which means it has one spatial dimension and one time dimension. We derived the fact that the quantum states of the black hole could be represented as the … Continue reading →

New Non-geometrical Generalization of the Principles of CFT Found?

Posted on November 17, 2004 by PlatoHagel

There is always a certain expectancy, when it comes having formulated the theoretical work, that further developement along these lines presenst the opportunities for such things to exist. A new non-geometrical generalization of the principles of CFT will be found, … Continue reading →

2004 Promises to be an Exceptionally Exciting Year in General Relativity and Gravitation

Posted on November 14, 2004 by PlatoHagel

But you shouldn’t imagine the mood as one of breathless anticipation. At least for the physicists present, a better description would be something like “skeptical curiosity”. None of them seemed to believe that Hawking could suddenly shed new light on … Continue reading →

Plato’s Cave and Heisenberg, 21st Century with Witten

Posted on November 2, 2004 by PlatoHagel

Breaking Symmetry Here I sit in Brane world and the idea of “Pants” reaching different dimenisons seems intrigueing to me. Far beyond the views that one see from the light shining, from the open mouth of the cave, some far … Continue reading →
