Good thread idea, although I prefer 'conjectures.'
The whole idea of if aliens visiting Earth is riven with paradoxes. A lot of them are based on our current understanding of physics and the
limitations of speed and energy. As far as we understand, the speed of light should be impossible due to the amount of energy it would require. Under
such Laws, it would take any local intelligence years to come here. The
don't have planets. The nearest planets we have found are
gas giants or orbit the wrong class of star at distances that rule out life as we know it. The information we have rules out the possibility of
intelligent life originating anywhere close.
It would therefore need to come from even further away, which returns us again to limits of speed and energy. Darwin's Beagle expedition lasted some
three years. Marco Polo spent nearly twenty years in China. Unless they can operate under conditions considerably removed from our understanding of
physics, it would require immense commitment to travel to Earth. AI, cyborg or longer lives? Could the commitment to exploration involve generations
born and died en route to targets? As Weedwhacker wondered, how would they relay the information back? Again, it would require generations.
We have to consider the possibility that UFOs are a phenomena not connected to visiting ET. Maybe in the future we'll have explanations for the
sightings that don't involve intelligent visitors? Who knows? We can only speculate and extrapolate from what we think we know.
Just speculating, if intelligent life is visiting us we have to wonder the whys, whats, wheres and whens.
Why? A more advanced race could have the same curiosity about different cultures that we have. Sir David Attenborough and his team remain neutral as
they film wildlife in it's natural habitat. They don't intervene. Whereas I watch the programs and feel pity as yet another calf, cub, baby, egg is
killed and eaten by a predator, the cameras roll and nobody attempts to save them. Why should an alien visitor act differently? Anthropologists don't
embark on studies of Amazonian tribes by giving them treatises on math or Leatherman pocket tools.
Continued speculation...the activities of these aliens is no different to the activities of us. We can take an animal from it's environment, swab it,
test it, take samples, tag it and release it back where we found it. The wee bugger is unharmed, but maybe is left with some anxiety? The observer is
strictly scientific and benign.
Back to the speed of travel and energy...sightings occur weekly over years. Many different...many unusual...If our understanding of physics is
complete, alien visitors are psychological aberrations on a mass scale. If there is much more to learn about the possibilities of space travel, we
could simply be case studies in some alien university and characters in some nature documentary on a foreign planet
