No Information Lost Here! Musings No one (at least, no one I talk to) has the slightest doubt that quantum gravity has unitary time evolution in asymptotically AdS space. Normally, I try not to devote attention to such things, but the flurry of discussion prompted me to take a look at the transcript of Hawking’s talk. Blackholes may form and evaporate in interior, but the overall evolution is unitary and is holographically dual to the evolution in a gauge theory on the boundary. golem.ph.utexas.edu /~distler/blog/archives/000404.html

Physics Today November 2002 "We talk about Newton's law of gravity, and then we talk about how you would build such a planet, and not make it a gas giant. Jim Kakalios, a condensed matter experimentalist and comics buff, analyzes questions like these from action comics to teach physics in a freshman seminar at the University of Minnesota-Twin Cities. The Bernoulli principle, time travel, and the biological and physical feasibility and implications of shrinking to the size of an atom or growing into a giant are among the topics Kakalios's class tackles through comics. www.physicstoday.org /vol-55/iss-11/p29.html   (626 words)

Artificial gravity needed for future space missions - MIT News Office Before a manned mission to Mars is feasible, an effective means of creating artificial gravity is needed to help prevent physical deterioration astronauts suffer during long space flights, said Dr. Laurence R. Young, the first Apollo Program Professor of Astronautics, at a talk last week. Artificial gravity created by spinning the spacecraft, possibly in the manner depicted in the movie "2001," may be the answer, he said. Variables such as optimum duration and level of artificial gravity, structural layout and habituation schedules need to be studied further, Dr. Young said. web.mit.edu /newsoffice/1995/gravity-1129.html   (757 words)

Warning: Gravity is "Only a Theory" by Ellery Schempp It is safe to say that without the Theory of Gravity, there would be no talk about a “Big Bang,” and important limitations in such sports as basketball would be lifted. For example, “the moon goes around the earth.” If the theory of gravity were true, it would show that the sun's gravitational force on the moon is much stronger than the earth's gravitational force on the moon, so the moon would go around the sun. His dabbling in gravity, alchemy, and calculus was a mere sideline, perhaps an aberration best left forgotten in describing his career and faith in a Creator. www.bringyou.to /apologetics/p67.htm   (1375 words)

Straight Dope Staff Report: Why does spinning a space station create artificial gravity? This is a key difference between artificial gravity and the real kind. Einstein tells us that gravity is actually just a fictitious force, too, but that doesn't stop physicists from treating it as real. You may find this talk of centripetal force confusing. www.straightdope.com /mailbag/martificialgravity.html   (1069 words)

Citebase - Semiclassical Gravity and Mesoscopic Physics Kuchar, Canonical Quantum Gravity, in General Relativity and Gravitation 1992, eds R. Gleiser et al (IOP, London, 1993) For a recent review of a general nature, see, C. Isham, "Structural Issues in Quantum Gravity", Plenary talk at GR14, Florence, August, 1995. A closer depiction of this primordial state of the Universe requires at least a semiclassical theory of gravity and the consideration of non-equilibrium statistical processes involving quantum fields. We give a summary of the status of current research in stochastic semiclassical gravity and suggest directions for further investigations. citebase.eprints.org /cgi-bin/citations?id=oai:arXiv.org:gr-qc/9511077   (1069 words)

Raman Research Institute Workshop on Loop Quantum Gravity He discussed several cosmological issues from the loop quantum gravity perspective; in particular he gave a detailed overview of the meaning of the initial singularity and initial conditions, evolution through classical singularities, large volume behavior and corrections to the classical approach to singularities. It was really impressive to see how far the developments on loop quantum cosmology have reached and the impulse that Martin's work is giving to the whole loop quantum gravity program. During two weeks in November and December 2002, approximately 20 researchers in quantum gravity gathered at the Raman Research Institute in Bangalore for an intensive meeting on Loop Quantum Gravity and related issues. www.phys.lsu.edu /mog/mog21/node17.html   (1069 words)

Center of Gravity and Roll-Over Angle - Jeepaholics Anonymous So often in our trail side conversations we talk about the CG (Center of Gravity) of one Jeep being higher or lower than the CG of another Jeep, and we relate this not only to the ability to get up or down a slope, but also to the dreaded thought of rolling over. Yet most of us have never really figured out where the Center of Gravity is actually located on our own Jeep and similarly what the Rollover Angles are. This write-up is an effort to provide a process that most folks can follow to determine, with a reasonable degree of accuracy, the Center of Gravity and Rollover Angles for their own Jeep. www.jeepaholics.com /tech/cog   (190 words)

Chunk#9 of EXTRATERRESTRIAL ENCYCLOPEDIA "Mission of Gravity" [Mission of Gravity, Hal Clement, Garden City NJ: Doubleday, 1954] has one of the most vividly rendered alien planets with ETs ever written. David N. Samuelson says that "the greatest weakness" in Mission of Gravity: is its characterization of its aliens. They look like centipedes with lobster claws, act and think like Renaissance sailors, and talk largely like [19]50s engineers, at least as they are represented in American SF. www.magicdragon.com /EmeraldCity/extraterrestrials/alien9.html   (3909 words)

Feynman's Talk It would be like this: After you have made a part and you unscrew the nut from a bolt, it isn't going to fall down because the gravity isn't appreciable; it would even be hard to get it off the bolt. It would be like those old movies of a man with his hands full of molasses, trying to get rid of a glass of water. There is the problem that materials stick together by the molecular (Van der Waals) attractions. www.zyvex.com /nanotech/feynman.html   (3909 words)

San Diego flight fans hope to find the right stuff in zero-gravity ride The San Diego Union-Tribune Before boarding the cargo plane for tomorrow's flight, operated by the Fort Lauderdale, Fla.-based Zero Gravity Corporation, Brezic and the other passengers will get a few hours of training, a pep talk from an astronaut and a meal low on proteins and dairy products (to minimize motion sickness). For about 30 seconds, as the plane reaches the top of the arc and then descends, gravity is suspended. Weightlessness is created when the pilot, starting at an altitude of about 24,000 feet, maneuvers the plane at a 45 degree angle to about 34,000 feet, then noses it downward. www.signonsandiego.com /uniontrib/20041008/news_1n8fliers.html   (3909 words)

Science Fiction Writer Robert J. Sawyer: Northern Lights In the fall of 1989, TVOntario, the television service of the Ontario Educational Communications Authority, began a weekly half-hour talk show about science fiction and comics called Prisoners of Gravity, hosted by Rick Green, formerly of the comedy troupe The Frantics. Announced April 30, 1992: the Reality 1 Commendations (the "R1Ckies") voted on by the viewers of TVOntario's Prisoners of Gravity : Tanya Huff 's Blood Price tied with Garfield Reeves-Stevens 's Dark Matter and Anne Rice's The Witching Hour for Best Horror Novel; and Charles de Lint won for Best Canadian Fantasy Writer. TVOntario's Prisoners of Gravity has been renewed for a second season; principal broadcast will be Thursday evenings at 7:30. www.sfwriter.com /northern.htm   (3909 words)

Gravity Recovery and Climate Experiment (GRACE) GRACE will be able to map the Earth’s gravity fields by making accurate measurements of the distance between the two satellites, using GPS and a microwave ranging system. The GRACE mission will accurately map variations in the Earth’s gravity field over its 5-year lifetime and the resulting improvements in precision of gravity measurements is expected to revolutionize our understanding of key climatological phenomena. The first NASA Earth System Science Pathfinder (ESSP) mission to launch is the Gravity Recovery and Climate Experiment (GRACE). www.odysseyofthemind.com /grace2.htm   (3909 words)

english.html In addition, there will be a special talk on the history of gravity research in Mexico. In addition, during the school we would like to discuss fundamental issues which are still open, such as problems in classical and quantum physics related to the quantization of gravity, and the unification of the fundamental interactions of nature, among others. Sixth Mexican School is therefore to present these different viewpoints on quantum gravity, including their most recent theoretical results and the way in which these approaches attempt to get closer to experimental predictions. www.nuclecu.unam.mx /~gravit/EscuelaVI/english.html   (321 words)

Web Lectures: Gabriela Gonzalez The talk spends about equal time on the theorem and its interesting history, and the application of this theorem to a system for gravity wave detection. The theorem represents a fundamental noise limitation on all measurements which she applies here to the analysis of a gravity wave interferometer. This talk grew out of her earlier thesis on the fluctuation-dissipation theorem, an important theorem on the power-frequency distribution of Brownian motion in different systems. physics.hyperjeff.net /lectures/gonzalez.01.html   (275 words)
