Physicists from Cornell and MIT have published a study exploring the mathematical framework for sending information backward in time. The research investigates retrocausal communication through the lens of quantum mechanics by modeling noisy closed timelike curves. By analyzing how these quantum channels operate, the study attempts to determine if a message from the future could reach the past without triggering a grandfather paradox or violating the fundamental laws of physics. #timetravel #quantumentanglement #science #newdiscovery
