In this book, we explore far-ranging techniques for future relativistic rockets. In this book, we explore the notion of converting a baryonic standard model spacecraft into a neutrino-like state. All the text from my book ?Call of The Cosmic Wild: Relativistic Rockets for the New Millennium, 6th Expanded Edition? has been included but interrupted by occasional new material to note and make clear the results of applying the neutrination mode to the spacecraft.
