-Demosthenes- Posted February 6, 2004 Share Posted February 6, 2004 I stumbled upon a couple pages about the "Einstein-Rosen bridge" While googleing Time Travel. (You know me ) I read what it was, but I didn't understand it completely. Something about negative square roots, Time travel, white hole, black holes, and other stuff. I would like to know what exactly it is and what everyone thinks about it. PS: I'm not really sure what the Einstein-Rosen bridge is to I hope it's not in the wrong forum. If it is you'll forgive me right Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 6, 2004 Share Posted February 6, 2004 Never heard of it, yet I'm reading a book about relativity right now. Strange. Possibly it's something like a wormhole, "bridgeing" you to other parts of the universe. Link to comment Share on other sites More sharing options...
-Demosthenes- Posted February 7, 2004 Author Share Posted February 7, 2004 This had something about worm holes too. That they connect white and black holes and stuff, or something like that. Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 7, 2004 Share Posted February 7, 2004 I told you! I'm reading a book about relativity, I can tell you if I find it. Link to comment Share on other sites More sharing options...
Guest Camaroofdeth Posted February 7, 2004 Share Posted February 7, 2004 In rotating black holes, this bridge can form making travel to another universe a mathematical possibility. The bridge is this Einstein-Rosen thing. I guess it could be like a wormhole. The white hole is where light from the black hole exists. I suppose that's where you would exit, assuming the black hole didn't smash you all to hell. Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 7, 2004 Share Posted February 7, 2004 It would! The difference in gravity from your legs to your head would rip you apart. Link to comment Share on other sites More sharing options...
Neurocomp2003 Posted February 7, 2004 Share Posted February 7, 2004 "einstein rosen bridge" was the name used before wormholes was coined by Kip thorne or John wheeler. It is the link between 2 black holes or 1 black hole 1 white hole. BLack hole of course "sucks everything in" while the white hole "lets everything out" Of course 2 black holes linked would be useless but it is a solution to the field equations. The problem with the white hole is that (as the solutions go) if ever it existed it would produce an energy so great that it would form an energy barrier ring around the singularity/ring thus trapping the traveller inside the white hole. I won't get into the physics of the barrier. One other solution is thtat the white hole would be not be sustainable because of this barrier and would just collapse. Either way it is all mathematical and has yet been observed of course. FUN WITH MATH. If you would like to find more about wormholes --> xxx.lanl.gov (los alamos nat'l lab) is a good source of papers. It helped me well on my paper of wormholes and time travel. And it describe a bit about negative energy. Link to comment Share on other sites More sharing options...
-Demosthenes- Posted February 7, 2004 Author Share Posted February 7, 2004 http://casa.colorado.edu/~ajsh/schww.html This is where I first read about it. The Schwarzschild metric admits negative square root as well as positive square root solutions for the geometry. What's this about geometry? Negative square roots and stuff? Does it have something to do with i? Thanks very much. Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 7, 2004 Share Posted February 7, 2004 I was reading about that Schwarzschild thing yesterday. Somehow, it's a figure determining at what point something is too dense to allow light to escape, or summat like that. I'll check. Link to comment Share on other sites More sharing options...

Neurocomp2003 Posted February 9, 2004 Share Posted February 9, 2004 what do you wanna know about the sch ..metric. Or other metrics? Link to comment Share on other sites More sharing options...
-Demosthenes- Posted February 9, 2004 Author Share Posted February 9, 2004 What? I want to know about the bridge thing and stuff. Link to comment Share on other sites More sharing options...
dhahranian1401 Posted February 9, 2004 Share Posted February 9, 2004 I remember a Sci-Fi TV show envolving those things called Sliders. The idea I got was that these "holes" are pathways between different parallel universes. Like for example, you could go to another universe in which anti-biotics weren't discovered yet, like in one episode. Another episode showed them going to a universe where Einstein screwed up the theory of relativity on perpous so that the nuclear bomb wouldn't be invented. Another one had a universe where male were the suppressed gender. I guess I went a little bit out of the topic Link to comment Share on other sites More sharing options...
Sayonara Posted February 9, 2004 Share Posted February 9, 2004 The wormhole in "Sliders" was actually meant to be an Einstein-Rosen bridge. The most stupid bit was the timer device. Link to comment Share on other sites More sharing options...
dhahranian1401 Posted February 9, 2004 Share Posted February 9, 2004 I think the timer device was there just for the suspence Link to comment Share on other sites More sharing options...
