Parallel tunneling is a technique used to create a tunnel through the space-time continuum. It requires a large amount of coffee, a map, a compass, and a strong will to survive the journey.
By using this method, one can travel through parallel universes, visiting alternate realities and experiencing the infinite variations of the multiverse.
The key to parallel tunneling is understanding the concept of probability and the power of the human mind. It is not a task for the faint of heart.
