1 Corinthians 13:2
"Theoretical routes to the past called time loops have long been hypothesized by physicists. But because they are plagued by impracticalities and paradoxes, they have been dismissed as impossible for just as long.
But now Lloyd and other physicists have begun to show that in the quantum realm, these loops to the past are not only possible, but even experimentally feasible.
In other words, we will soon effectively try to send a particle back in time.
If that succeeds, it raises the possibility of being able to dispatch, if not people, then at least messages in the form of quantum signals, back in time."
