Thor's mortal muse (I forget the name) says to Darcy: "An Einstein-Rosen Bridge is a theoretical connection between two different points of space-time. lt's a wormhole."
But the S.H.I.E.L.D director, at the end of the movie, says to Dr. Selvig: "Your work has impressed a lot of people who are much smarter than l am. The Foster Theory. A gateway to another dimension. lt's unprecedented."
I thought wormholes transported you to different points in our own dimension? And the Bifrost animations looked a lot like they were travelling between planets.
Unfortunately, I know nothing about the Einsten-Rosen bridge, so I do not understand. Are the different "-gards" in different locations of our universe, or different dimensions?
