Interstellar's Display of a Wormhole and the Physics Behind It
The movie Interstellar displayed many astrophysical phenomena of which had barely ever been displayed in major motion pictures before. In able to gain a good foundation for the physics behind wormholes, I read chapter 14 and 15 of the book The Science Behind Interstellar by author Kip Thorne. The wormhole displayed in the move was what Thorne referred to as a "traversable wormhole". A traversable wormhole's properties that make it different than a normal one is that it contains exotic matter. A traversable wormhole can most likely only be created unnaturaly. This is because the only exotic mater that humans have ever encountered is when we created it in a labratory. Spacetime is converged when seen from outside of the wormhole, but diverged when seen from inside the wormhole. A simple mass will cause spacetime to be converged, such as the top of Figure 1, but the divergence of spacetime requires a negative mass, or negative energy, in accordance to Einstein's
