Well, that's all well and good... but, how do you get home when you are creating divergence by simply being here?
Divergence occurs when a time traveller moves just a few atoms or molecules. This may alter local gravitational forces, temperature, fluid dynamics, and other molecular traits. As described in Twentieth-Century chaos theory, moving a single molecule can lead very quickly to significant seismic and climatic changes around the world. For example, moving a single air molecule in South Africa could alter the wind patterns in the immediate area, which in turn could alter the weather throughout the Southern Hemisphere, which in turn would cause a storm in a specific location, which could lead to temporal divergence at the genetic level.
The seeming randomness that you create simply by being, must make a return journey hazardous at the best of times... so how do you do it? What is your vehicle for this and how do you keep track of where you are and whence you came from against this hostile backdrop of divergent chaos?[/b]
