Understanding the Unidentified

“No hypothesis or theory in any field accounts for 100 percent of the phenomena under investigation. The ‘residue problem’ means that no matter how comprehensive a theory is, there will always be a residue of anomalies for which it cannot account. The most famous case in the history of science is that Newton’s gravitational theory could not account for the precession of the planet Mercury’s orbit, subsequently explained by Einstein’s theory of relativity. … The residue problem in UFOlogy is instructive because it enables skeptics to find common ground with believers and allows us to live comfortably with the fact that we can’t explain everything.” (06/03/21)
