I enjoyed that episode, and the lack of evidence of a Voth culture on Earth can be easily explained by plate tectonics. The remains of their civilization is buried so far below the surface that it would be risky to impossible to try digging any of it up.
Possibly. It helps to roll with the premise. If one can do so for Space 1999, then anything is possible.

Besides... when you look at the basic plot elements, it's a retelling of the Galileo story. Scientist finds evidence that leads him to a theory that clashes with current religious doctrine. Scientist is sufficiently threatened with all kinds of dire consequences and forced to recant his theory if he wants any sort of tolerable life in the time remaining.
Good point...
Of course the Voth scientist was more fortunate than Galileo... he wasn't put under house arrest and he hadn't gone blind (which Galileo did from doing too many observations of sunspots through his telescope).

Something I came up with many years ago when our local Star Trek club designed our own ship was that we'd gotten hold of the Kelvan technology that turns people into little styrofoam dodecahedrons... and modified it for non-organic things.
If our 23rd-century crew could do that, just think what would be possible in the 24th century. Janeway actually had several supply closets stuffed with shuttles and torpedoes that were in the form of little styrofoam dodecahedrons. When she needed another one, they'd just pick it up from the supply closet, push a button to return it to its original form, and boom. Problem solved.
Nice...
