Gypsy...virtually? i know many places where this word is used where it does not mean what it says..

Vivian,

There are things which exist and you cannot see them. Example, modulation which carries your voice when you make a mobile fone call. Your voice is transmitted from the handset and you cannot see it through the air, but it there!

when you hear the person calling, you get sure the voice is on the air without seeing it, because you saw the evidence.
