Accordingly, the author delves into plausible methods of enabling relativistic rocket flight at velocities extremely close to the speed of light in a vacuum. Conjecture on methods of steering otherwise random or probabilistic quantum processes are considered. Additionally, speculation is provided on extracting energy from zero-point field sources. Many other topics are also addressed. This book is definitely not for those unwilling to consider almost mystical approaches to the problem of extremely relativistic space flight. However, if you have the courage to take the plunge into some truly exotic proposals, then this book is likely a must read for you.
