![]() Seen in person, a wormhole would be a sphere. In two-dimensional diagrams, the wormhole mouth is shown as a circle. Such wormholes cannot form naturally, however.īeings able to control gravity and travel through the Bulk could create wormholes and cross space much faster than light. Objects approaching the singularity pass through an event horizon from which they can never return. If two singularities in far-apart locations could be merged, a wormhole tunnel through the Bulk could be formed. If enough mass is concentrated at a point, a singularity is formed. Our three-dimensional universe can be thought of as a flat membrane (or "brane") floating in a four-dimensional void called the "Bulk." The presence of mass distorts the membrane as if it were a rubber sheet. So on a planet orbiting close to a black hole, a clock ticks much more slowly than on a spaceship orbiting farther away. One feature of Einstein's equations is that time passes slower in higher gravity fields. ![]() ![]() The black hole's complex appearance in the film is due to the image of the accretion disc being warped by gravitational lensing into two images: one looping over the black hole and the other under it. ![]()
