It's possible that the idea of sending information into the past may make quantum mechanics less mysterious
EXCERPT: [....] The problem with the traditional Copenhagen interpretation of quantum mechanics is that it requires this information to somehow be "known" by the whole system instantaneously. This is the issue of nonlocality, which has been confirmed by experimental tests of Bell's theorem. And that causes problems with relativity, because no information should be able to travel faster than the speed of light. In Cramer's interpretation, the information sent by the measurement of the system goes not merely out into the future at the speed of light, but also backward in time at the speed of light. This time-reversed wave of information comes into contact with the entire system when they were close together, back when they actually became entangled. The theory is fully nonlocal, but it requires no violation of relativity....
Scientists find a way to resolve quantum time travel paradox
EXCERPT: An international team of scientists might now have solved the mystery surrounding this difficult paradox to give quantum time travel theory a boost. In the study, published in the International Journal of Quantum Information, scientists claim that they have found a way to break the closed timelike curves (CTCs) to resolve the time travel paradox of quantum physics. [...] “[It] is completely isolated from anything that can affect its own causal past during the time-traveling process,” the study states, according to The Epoch Times....
