Only when people said that there is a splitting of the whole universe when we 
do a measurement, but as I said, it is only consciousness or first person 
experience which differentiates, and it can affect the body and the environment 
only at the speed of light. Instantaneity has virtually no meaning to me, since 
special relativity.
