This question already has an answer here:
Now, physicists are trying to send information backward in time. But, why are physicists almost sure that this would happen and why are they so confident about it? Did physicists solve the grandfather paradox?
In that case it would mean that result would occur before the cause. That is very weird. Of course the universe is very weird(and hence very interesting) but is that the case? Can information be sent backward in time?
