The wormhole was perfect, except the travel bit bugged me. They use the 2d analog with paper. The second you pass through the hole in one location you emerge from the hole in the other location. In the third dimension, as they touch the sphere near Saturn they would be leaving the surface of the sphere on the other side. From their point of view they should be about to hit the 'ball' then all of a suddenly then are travelling away from the surface of another ball. Instead they had this tunnel thingy.

Wheeler and Robert W. Fuller published a paper showing that this type of wormhole is unstable if it connects two parts of the same universe, and that it will pinch off too quickly for light (or any particle moving slower than light) that falls in from one exterior region to make it to the other exterior region.

- snowballsteve 12y agoYea I was thinking about that, say a straw. A cylinder to us in the 3d world but in the 2d world one would just see themselves stuck in a circle for awhile. So to up a dimension a 4d whole in a 3d world would I guess appear to us to be a stuck in a sphere? Maybe that is what the movie tried to show, but it still looked like they were travelling in a tube.
