Not sure what section this would belong in but; How far from a possibility are they?
There's a very strong possibility for their existence, as long as you're not thinking in the Science Fiction popularization aspect. It's next to impossible that you could ever find, create, or maintain a wormhole big enough for a rabbit to pass through, let alone a spacecraft . The amount of negative energy required to sustain the input end would be more than most of the positive energy in the universe. You could also never determine where the other end would be.vincentm said:Not sure what section this would belong in but; How far from a possibility are they?
Not the laws, just the practicality. It's like saying that theoretically you can achieve 99% of light speed in a spacecraft , but where would you get the energy to do it?vincentm said:That the theory of them don't violate the laws of physics.
scott_alexsk said:Yes but could one create one with ideal conditions? How would this be done?
Dr.Brain said:By definition , Worm Holes are 'black holes' and 'white holes' joined end to end.
I also don't know where I got that estimate, but I'm pretty sure it was just a SciAm article sometime last year. The reference was to negative energy, though, not mass. If a few Jupiters worth of negative mass was converted to negative energy according to e=mc^2, it might do the trick.pervect said:Estimates I've seen put the negative mass to stabilize a wormhole much lower than the mass of the universe - a few Jupiter's should do the job :-).
I don't recall exactly where I got this figure, though, so take it with a grain of salt. (But take the other larger figure with a grain of salt as well, unless the source for it can be tracked down).

Yes.ohwilleke said:I'd say that the evidence for the existence of wormholes is nil,.
Depends on whom you listen to.and that the theoretical basis for them is pretty weak.
I'm not sure I know what you mean. Could you elaborate?On the other hand, a truly non-local wormhole would connect two points through a means other than the curvature of time-space.
Currently, wormholes are still just a theoretical concept. They have not been observed or proven to exist in our universe.
The idea of using wormholes for time travel has been explored in science fiction, but in reality, it is currently not possible. The physics of wormholes and time travel are still not fully understood and there are many theoretical and practical challenges that would need to be overcome.
Wormholes are hypothesized to be created through the warping of spacetime, which can occur through the presence of extreme gravitational forces such as those found in black holes.
The distance that a wormhole can span is still unknown and is a subject of ongoing research. Some theories suggest that wormholes could connect two points in space-time that are relatively close to each other, while others propose that they could span vast distances across the universe.
At this point in time, the technology and understanding necessary to travel through a wormhole do not exist. However, scientists continue to explore and research the concept of wormholes, and it is possible that in the future, we may discover a way to make wormhole travel a reality.
