Without passing judgement on Grey's claim to FTL signaling, his use of
the word "imaginary" would be better served by "imaginal".
"Imaginary" carries the connotation of being
nonexistant or having no factual reality.. while "imaginal" connotes
real imaging, like seeing from an alternate referance frame. After all,
relativity itself is all about seeing clearly *and experientially* from
alternate frames. oc
