Travel and Behavior
Other objections to the study of UFOs and the possibility of extraterrestrial visitation of Earth have occasionally been used as absolutist rejections of the concept. Of these, the commonest may be the inadequacy of space travel technology and the so-called "Fermi Paradox." Both of these have been rigorously and negatively critiqued, if not wholly dispensed with. A few remarks on each will be sufficient here, and will serve to develop some views particularly germane to the UFO phenomenon.
