containscotton Posted August 13, 2011 Share Posted August 13, 2011 I know wormhole travel is supposed to be theoretical and unproven, but what is the explanation by proponents of wormhole travel for the fact that the "instantaneous" movement from one space to another has frames in the past, therefore sending information not only back into the past but also making the universe at that moment of time have more energy than it did previously? Or did I misunderstand something? Sorry about my English. It's not my first language. Link to comment Share on other sites More sharing options...
questionposter Posted August 13, 2011 Share Posted August 13, 2011 (edited) A wormhole does not violate anything because it doesn't "create" anything, it simply brings two points of 3 dimension or 4 dimension space (or both) together at another singular point, which is why diagrams often describe it as a bending of the fabric of space. All your doing is moving the position of space and time. Time in special relativity is its own dimension that occupies all of space, it doesn't get created or destroyed, it simply moves or flows in its own 4 dimensional manners.

containscotton Posted August 13, 2011 Author Share Posted August 13, 2011 Sorry, most of that flew over my head. A wormhole does not violate anything because it doesn't "create" anything I never said it did, I was confused about it bringing information into the past. it simply brings two points of 3 dimension or 4 dimension space (or both) together at another singular same point What, is there a third point now? Even so, if it's in the same universe, doesn't the frame in the past still apply to the universe? which is why diagrams often describe it as a bending of the fabric of space. All your doing is moving the position of space and time. Time in special relativity is its own dimension that occupies all of space, it doesn't get created or destroyed, it simply moves or flows in its own 4 dimensional manners. Can you specifically define what it means to move the position of spacetime? Link to comment Share on other sites More sharing options...

Even so, if it's in the same universe, doesn't the frame in the past still apply to the universe? Well, your bringing one point to the other then, as long as both are occupying the same point, it doesn't matter where that point that they meet is. Can you specifically define what it means to move the position of spacetime? It's not much different than bringing two corners of a piece of paper together. With time, your bringing two coordinates of time together at the same dimensional point, so two different coordinates of time I imagine would be dates like in march 21st, 1995 and today. Since its still the same fabric of time, both dates are just points in 4 dimensional space, there's nothing being created or destroyed.

There is no global notion of time in general relativity, so there is no "moment of time" that applies to the entire universe. Conservation of energy in general relativity holds at a point, but not over a finite volume. Link to comment Share on other sites More sharing options...

Well maybe not in "general" relativity, but what about "special" relativity where wormholes can actually occur? In special relativity there is in fact a fabric or medium for events that consists of 3 dimension space + the dimension of time which effects matter and our perception of time like with time dilation.

They cannot occur in special relativity. "Special" in this case is a more restricted set of rules and does not allow space-time to fold back on itself. "General" may allow it, though I suspect reality may not. Link to comment Share on other sites More sharing options...

Isn't general relativity the thing that predicts a fabric of space-time and provides a diagram for black holes which wormholes were based off of? Isn't it that they are possible but they would collapse too fast? Edited August 13, 2011 by questionposter Link to comment Share on other sites More sharing options...

(I doubt they occur in reality) You stated that they can actually occur in SR, unless I misread what you meant by "special". Link to comment Share on other sites More sharing options...
