I never met a writer who couldn't come up with an explanation. They had observation devices but not close enough for the whispered details. They had an informant who knew the arrangement was planned but didn't know the data itself. Maybe they just added two and two going in, to guess the obvious: the development of an asset would be attempted. Personally I suspect they ran tachyon particles in reverse through the transporter.how the Moclans knew
The writer is God, omniscient and all-powerful in his little universe.
