Quantum Retrocausality

Remember this classic strip from Calvin and Hobbes where past Calvin writes a letter to future Calvin and Hobbes comments

"Too bad you cant write back"

Now if what John Cramer says he can do is correct then Calvin for sure has reason to smile. According to The Register , John Cramer has claimed that he can send information back in time through a process called quantum retrocausality. Now if you ask about "Quantum retrocausality", the engineering-degree-a-long-time-ago desk at The Register opines that all they really know about quantum is that it's pretty wild stuff and I tend to agree. So Dubara mat poochna :)
