just a comment on the cat in a box thing.
ive been thinking about this and have come to this conculsion
years ago I moved from Corby to near Peterborough, and I left alot of people behind, who ive never seen again, so in effect they were put in a box (for me) meanwhile Corby is a dumped and a high crime area, meaning they could be killed for some reason (that or just the dangers of life) those people are probaly still alive, but according to the theory they are both alive & dead.
even if a person can not see in the box (or the people at Corby) does not change if they are actually dead or not, they are not both dead & alive, only when they actually die are they dead, until then they are living. My not knowning of there death changes nothing.
like the tree that falls when no one is around, the sound waves are made, but are like an LP without a record player its sound will go unheard.
