On 9 January 1992, radio astronomers Aleksander Wolszczan and Dale Frail announced the discovery of two planets orbiting the pulsar PSR 1257+12. This discovery was confirmed and is considered to be the first definitive detection of exoplanets. Humans have since identified some 4,500 exoplanets, another 6,000 targets and theorize 11 billion exist in the Milky Way galaxy alone. This book was inspired by factual astrophysical data, where travel to and from these strange new worlds is just a matter of (space and) time. The explosion of astrophysics begs for the injection of some fiction into the universe of science facts all the while celebrating the plethora of data which is being gathered at an accelerating rate, along with the technology to derive better understanding of this data and what humankind intends to do with this collected knowledge about space – the last and greatest frontier.

This story uses the explosion of technical knowledge of how the universe works, as we understand it today. We follow Tucker on a journey through our galaxy, the Milky Way, and the Local Neighborhood, including Andromeda, Triangulum and a host of dwarf galaxies. The path continues to the larger structures of the universe, and how they are being held in place by Dark Matter and torn apart by Dark Energy. Time is a relative concept and takes on a different meaning when traversing the vastness of space. The notion that space is like a sea, navigable by mechanical means, and usually only for hostile purposes is countered by the presentation of a more benign, though equally treacherous cosmos. Wormholes, whether Schwarzschild wormholes. Einstein–Rosen bridges, or Flamm's Parabola, are the only ways to cross the vastness of the universe, though not in a human life span. This is not about time travel within our home planet, but exploring other galactic and supercluster structures that require travel to other natural or synthetic exoplanets. It also addresses varieties of DNA (aliens) and how that is manipulated and distributed. Data science, telemetry, physics and astrophysics are all interconnected with human transition. This is a transition in three parts - Hitchhiker Gods is the overarching theme, Parabola Pirates focusing on exploring the Local Neighborhood, and Hydrogen Helix, exploring supercluster structures of Virgo, Laniakea, and the supercluster neighbors attached to it.
