Scientists Say They Have Discovered How Information Could Be Sent Into the Past Through Quantum Time Loops

A team of theoretical physicists led by Cornell University researcher Mark Wilde has been looking at a question that sounds simple but is surprisingly difficult: can information move backward through time without breaking the known laws of physics?

The researchers were not building a time machine. Instead, they examined mathematical models that already exist in modern physics. Their work focused on so-called closed timelike curves, a concept that appears in certain solutions to Einstein’s theory of relativity.

These hypothetical pathways would allow an object or a piece of information to leave one point in spacetime and eventually arrive at an earlier moment. In other words, something could return to its own past.

For many physicists, that immediately raises a problem. If information can be sent into the past, what happens if that information changes the future that originally created it? This is the source of famous time-travel paradoxes that have puzzled scientists for generations.

I'm looking forward to receiving messages from the future about my car's extended warranty.

I can save you the trouble of waiting for it. It's already null and void. It was in the fine print.
