According to Quantum Mechanics future can affect the past.
There are many names for this “QM weirdness”; retro-causality, time flying backwards and so on…
Experiment Shows Future Events Affect The Past
There are just as many interpretations of this supposed weirdness that QM presents scientists with…Some say that we don’t know enough about TIME…Others say there is no such thing as time; at least on quantum level…
Though initially opposed or uncomfortable to with the problems QM presented him with, Einstein, just before he died, made the following statement about TIME itself.
Einstein once wrote, in a letter to comfort the widow of a recently deceased friend, “Now he has departed from this strange world a little ahead of me. That means nothing. People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion.”
