   You cannot point to a single scientific experiment and/or observation   
   that supports retrocausality vis-à-vis some sort of "time travel".  As   
   for #2, we will have to agree to disagree.  No theoretical physicist   
   believes that any and all solutions to GR/QFT is indicative of some   
   natural occurrence in the real World.  As with supersymmetric particles,   
   no experimental evidence exists for tachyons, and by the principle of   
   parsimony (Occam's razor), we are completely free to dismiss them   
   entirely as being fictional.
