Not only that, it would completely blow our minds.  If a signal is sent back
in time from the future, it would rely on particles of imaginary mass.  How
can we ever rely on any signal that is sent using imaginary mass?  We would
need to assume the signals are false.  I wouldn't be able to trust my future
self, if he sent me a warning signal to not make an investment for instance.
He knows, because he made that investment when he was me, back when then was
now, and lost money.

 

Oh the confusion.  If causality is violated, we will not be able to trust
anything.
