 Stable Lorentzian Wormholes in Dilatonic Einstein-Gauss-Bonnet Theory
These wormholes are more of interest to particle physicists. Wormholes are great theoretical fun, and are seemingly valid solutions of the Einstein equations.
Archived from the original on June 27, I’d like to read this book on Kindle Don’t have a Kindle? The role of wormhole physics in developing a quantum theory of gravity, via the quantization of weak field gravity and the subsequent appearance of gravitons is treated also.
Thorne leading off the discussion. Customers who viewed this item also viewed.

In the Voyager episode ‘Eye of the Needle’, the crew find a wormhole that could send them back home so soon after beginning their voyage. I was surprised to learn that the study of wormholes goes as far back as in paper by the physicist L.
The equations of the theory of general relativity have valid solutions that contain wormholes.
Again, what is gotten out of it depends on your background. Chronology protection conjecture Closed timelike curve Novikov self-consistency principle Self-fulfilling prophecy Quantum mechanics of time travel.

Formalizing this idea leads to definitions such as the following, taken from Matt Visser ‘s Lorentzian Wormholes When the infalling stellar matter is added to a diagram of a black hole’s history, it removes the part of the diagram corresponding to the white hole interior region, along with the part of the diagram corresponding to the other universe. In order to satisfy this requirement, it turns out that in addition to the black hole interior region that particles enter when they fall through the event horizon from the outside, there must be a separate white hole interior region that allows us to extrapolate the trajectories of particles that an outside observer sees rising up away from the event horizon.
Black holes Most massive Nearest Quasars. One type of non-traversable wormhole metric is the Schwarzschild solution see the first diagram:. This is why asteriods and comets pick up in the Oort cloud in a flash of speed.
However, he does devote a wormhole paragraph to the consideration loerntzian an energy-dependent effective topology which is the one of relevance to physics. The only available star is our Sun which is probably not a good idea to do.
Negative mass is not anti-matter, it’s a region where the energy of the universe is less than that of ordinary vacuumdefinitely weird stuff. In some hypotheses where general relativity is modifiedit is possible to have a wormhole that does not collapse without having to resort to exotic matter.

Wormholes, and rotating black holes Note that the Schwarzschild metric describes an idealized black hole that exists eternally from the perspective of external observers; a more realistic black hole that forms at some particular time from a collapsing star would require a different metric.
Alternatively, another way is to take one entrance of the wormhole and move it to within the gravitational field of an object that has higher gravity than the other entrance, and then return it to a position near the other entrance. A follow-up paper to Misner and Wheeler December He discusses in detail the result that the ANEC condition can be violated by scale anomalies.
For a simplified notion of a wormhole, space can be visualized as a two-dimensional 2D surface. The most well known of these three people is Albert Einstein, the German born American scientist.
And, before assailing any of this material, understand the formalism of “WKB-approximation.
