(In a vacuum, “Am I not?” could only be construed as some sort of philosophical counter-Descartian pondering.) In light of this dependence, the comma is more apt then the semicolon.
A perfect vacuum would be one with no particles in it at all, which is impossible to achieve in practice. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they simply call "vacuum" or "free space", and use the term "partial vacuum" to refer to real vacuum.
Considering their primary meanings, vacuum is used more often in a scientific context, in which case it means space completely or partially absent of any matter/air. It is a scientific term, while void can be used non-technically in a more abstract sense, but it can also be used when talking about empty space in a non-scientific way.
