evil said.....It isn't that what is there isn't true until you observe it. It is that you must observe it to know what state it is in....

if only that was the case....it is in all states until the wave collapses...there are trickey experiments with lots of mirrors that show this ...thats what freaked everyone out ....

its not that is in a certain spin state that you just dont know...it isnt

hence the whole problem with an objective underlying reality..
