WRONG!!!!!!!!!!!!!!
A vacuum is a volume of space that is substansively empty of matter, so that gaseous pressure is much less than standard atmospheric pressure. The root of the word vacuum is the Latin adjective vacuus which means "empty," but space can never be perfectly empty. A perfect vacuum, known as "free space", with a gaseous pressure of absolute zero is a philosophical concept with no physical reality, not least because quantum theory predicts that no volume of space is perfectly empty in this way. Physicists often use the term "vacuum" slightly differently. They discuss ideal test results that would occur in a perfect vacuum, which they simply call "vacuum" in this context, and use the term partial vacuum to refer to the imperfect vacua realized in practice!!!
So ya got that from Wikipedia he?

Still, i'm right, you just said it, a place empty of matter, if you were in the room, with air in it, and the psi wheel the room was not a vacuum.
