This type of wormhole would hide electromagnetic waves from view from the outside. The new wormhole isn't a space-time wormhole per se, but is instead a realization of a futuristic 'invisibility cloak' first proposed in 2007 in the journal Physical Review Letters. So far, no one has found evidence that space-time wormholes actually exist. Theoretically these Einstein-Rosen bridges, or wormholes, could allow something to tunnel instantly between great distances (though the tunnels in this theory are extremely tiny, so ordinarily wouldn't fit a space traveler). In 1935, Einstein and colleague Nathan Rosen realized that the general theory of relativity allowed for the existence of bridges that could link two different points in space-time. The idea of a wormhole comes from Albert Einstein's theories. 'From a magnetic point of view, this device acts like a wormhole, as if the magnetic field was transferred through an extra special dimension.' 'This device can transmit the magnetic field from one point in space to another point, through a path that is magnetically invisible,' said study co-author Jordi Prat-Camps, a doctoral candidate in physics at the Autonomous University of Barcelona in Spain. In 1980, the faculty of the Physics Department elected Jim to an adjunct professorship in the department in recognition of his ongoing research.Ripped from the pages of a sci-fi novel, physicists have crafted a wormhole that tunnels a magnetic field through space. Shortly after his arrival at CSUF, he established friendships with colleagues in the Physics Department who helped him set up a small-scale, table-top experimental research program doing offbeat experiments related to gravitation – experiments which continue to this day. On completion of his graduate studies, Jim took a teaching job in the history of science at California State University Fullerton (CSUF), where he has been ever since. For his Ph.D., he changed to the history of science, writing a dissertation on the history of attempts to deal with the problem of “action-at-a-distance” in gravity theory from the 17th to the early 20th centuries (Ph.D., University of Denver, 1972). From his undergraduate days, his chief interest was in gravitation.

Jim earned bachelor’s and master’s degrees in physics at Middlebury College and New York University (respectively) in the 1960s. Woodward is a professor of history emeritus and adjunct professor of physics at California State University Fullerton. The second addresses experimental investigations into the feasibility of the predicted effects that is, do the effects exist, and can they be applied to propulsion? The third part of the book - the most speculative - examines the questions: What physics is needed if we are to make wormholes and warp drives? Is such physics plausible? And how might we go about actually building such devices?ĭr.

The first discusses the theories of relativity needed to understand the possible propulsion techniques. Making Stars and Stargates has three parts. There has been progress on both the theoretical and experimental fronts since early 1990s. A less ambitious, but nonetheless revolutionary, goal is finding a way to accelerate a spaceship without having to lug along a gargantuan reservoir of fuel. It also set the benchmark for what has to be done to achieve truly advanced propulsion.īeing able to create the stupendous exotic mass of stuff needed to make stargates and warp drives is the holy grail of advanced propulsion. Thorne's work put discussion of rapid spacetime transport on the public agenda of serious science. The key requirement that Thorne identified was the creation of a Jupiter mass of 'exotic' matter - that is, matter with negative rest mass. That situation changed when Kip Thorne, instigated by Carl Sagan, reverse engineered the general relativistic requirements for any technology purporting to enable such rapid spacetime transport. Until the 1980s, all this was regarded in the serious scientific community as speculative, if entertaining, silliness. What is needed to get around the galaxy quickly has been known in science fiction since at least the 1960s TV's Star Trek made famous 'warp drive' and a bunch of attendant, less well-known 'technologies.' Some of the episodes even featured 'stargates,' portals to the distant past or future.
