This book contains a wealth of information regarding tachyons. Dr. Hans Nieper shares information from a meeting in Hanover, Germany in November, 1980 where "the tachyon energy of the extremely energy-rich field in space was, for the first time, deeply explored." Dr. Nieper also discusses gravity effects, tachyon fields, various types of free energy, and so much more!
Dr Nieper, an Internist from Germany, died in 1998. He had a fascination with theoretical physics and spent his life involved with clinical experiments and research.
