Research Methods
TIGHAR has called on a wide variety of scientific disciplines to help test the Niku Hypothesis.
- Oceanology: reef formation, tide studies.
- Meteorology.
- Forensic anthropology.
- Celestial navigation.
- Materials testing.
- DNA testing.
- Archaeology.
- Aerodynamics (calculation of range of the aircraft).
In addition, TIGHAR has done a great deal of archival and historical research, guided by the conviction that contemporary, first-hand accounts (primary sources) are to be given more weight than anecdotes, legends, or memories recorded at a much later date. Whether history is to be ranked as a science is something for historians, historiographers, and philosophers of science to debate among themselves. TIGHAR has made every possible effort to present the documentation for its case by assembling the primary sources in Research Bulletins.
