Exploring the Possibility of Wormhole Creation: A Scientific Perspective

[QUOTE="Umaxo, post: 6032933, member: 615386"] Hi, if i understood correctly from pop-science literature, there is theoretical possibility of formation of wormholes like in this picture: [URL]https://en.wikipedia.org/wiki/File:Wormhole-demo.png[/URL] bud you need some exotic particles (i think it means negative energy?). Now what i really don't understand - how is this possible? General realitivity doesn't describe topology of spacetime, you need to assume it. So why this talk about exotic particles, or quantum foam, or entaglements or whatever they talk in popscience as possibility for creation of wormholes? I would imagine that even in empty space i can decide to identify certain parts of the spacetimes, or insert some (flat) bridge (cylinder) between them and still have flat, minkowski metric that describes whole spacetime with wormhole without need of any particles. Sorry that i don't have specific quote form those pop-science books. So i would be glad just for some brief words on where the research of wormholes that you know of (those that connect certain part of space otherwise separated by long distance, not wormholes like einstein-rosen bridge in schwarzschild that makes no shortcut between two distant points of spacetime) stands in respect to my objections above. Thanks [/QUOTE]
