    For the 2010 TV mini series with the same title used in the United Kingdom Into The Universe with Stephen Hawking Stephen Hawking s Universe is an astronomical documentary from 1997 made for the Public Broadcasting Service featuring the theoretical physicist Stephen Hawking . The six episode series discusses the history of astronomy as well as black holes and dark matter . Episodes Seeing is believing In the beginning Cosmic alchemy On the dark side Black holes and beyond An answer to everything An extensive http www.pbs.org wnet hawking html home.html online companion site was produced to accompany the documentary. The online companion covers history of cosmology, unanswered questions and other topics related to the program. It was designed to function as both a supplement to the series and a stand alone web piece. Along with details explaining terminology, different models of the universe, biographies of famous historical figures in cosmology and content derived from the program, the web companion included discussions by contemporary cosmologists of unsolved mysteries , an opportunity to ask questions, as well as suggestions for experiments. One of the episodes, On the dark side , related the possibility of hyperspace travel and explored the technology of the Star Wars franchise.

  1. Gibbons?Hawking effect

    The Gibbons Hawking effect is the statement that a temperature can be associated to each solution of the Einstein field equations that contains a causal horizon. It is named after Gary Gibbons and Stephen William Hawking . The term causal horizon does not necessarily refer to event horizon s only, but could also stand for the horizon of the visible universe, for instance. For example, Schwarzschild metric Schwarzschild spacetime contains an event horizon and so can be associated a temperature. In the case of Schwarzschild spacetime this is the temperature math T math of a black hole of mass math M math , satisfying math T propto M 1 math see also Hawking radiation . A second example is de Sitter space which contains a particle horizon . In this case the temperature math T math is proportional to the Hubble constant Hubble parameter math H math , i.e. math T propto H math . References Gibbons, Hawking.

More precisely, it is a hypothetical Vector geometric vector in the Hilbert space of a theory of quantum gravity that describes this wave functional mathematics functional . It is a functional of the metric tensor defined at a D 1 dimensional compact surface , the Universe, where D is the spacetime dimension. The precise form of the Hartle Hawking state is the path integral over all D dimensional geometries that have the required induced metric on their boundary. Such a wave function of the Universe can be shown to satisfy the Wheeler DeWitt equation .

  1. Gibbons?Hawking?York boundary term

    In general relativity , the Gibbons Hawking York boundary term is a term that needs to be added to the Einstein Hilbert action when the underlying spacetime manifold has a boundary. The Einstein Hilbert action is the basis for the most elementary variational principle from which the Einstein field equations field equations of general relativity can be defined. However, the use of the Einstein Hilbert action is appropriate only when the underlying spacetime manifold math mathcal M math is Closed manifold closed , i.e., a manifold which is both compact manifold compact and without boundary. In the event that the manifold has a boundary math partial mathcal M math , the action should be supplemented by a boundary term so that the variational principle is well defined. The necessity of such a boundary term was first realised by James W. York York and later refined in a minor way by Gary Gibbons Gibbons and Stephen Hawking Hawking . For a closed manifold the appropriate action is math mathcal S EH mathcal S GHY frac 1 16 pi int mathcal M mathrm d 4 x sqrt g R frac 1 8 pi int partial mathcal M mathrm d 3 x sqrt h K math , where math mathcal S EH math is the Einstein Hilbert action, math mathcal S GHY math is the Gibbons Hawking York boundary term, math h alpha beta math is the induced metric on the boundary and math K math is the trace of the second fundamental form . Varying the action with respect to the metric math g alpha beta math gives the Einstein field equations Einstein equations the addition of the boundary term means that in performing the variation, the geometry of the boundary encoded in the induced metric math h alpha beta math is fixed. There remains ambiguity in the action up to an arbitrary functional of the induced metric math h alpha beta math . The equations of motion constrain the extrinsic curvature to be zero.
