This biggest qualm I have about this article is that it attempts to disprove alien tech using human tech. Any sufficiently advanced beings would appear to us to be magical of sorts since they would have mastered elements of the universe we don't even know exists.

What if they discovered a noble gas in the compound? (kryptonium perhaps) It would completely change the way we view chemistry.
