     I suggest that the perpendicular universe to another is that in which everything is opposite to the one in question. Perpendicular to this one, we would all be made of anti-matter. 1+1 would be -2. The sun would be a weak black hole.

     Your residence in a perpendicular universe is once more confirmed. Ronald Reagan ranted about smaller government his whole term, and left us with a bigger establishment than when he left.

     Aaron, you've heard of parallel universes, I imagine? Alternate realities related to ours that never intersect? Well, there are also perpendicular universes--universes that cross over with ours at one point and one point only.
