Weird Quantum Discovery Says Pushing Particles Forward Can Make Them Go Backward

Scientists discover a counterintuitive property of quantum particles called "backflow".

Quantum mechanics continues to provide brain-busting discoveries as mathematicians find that quantum mechanical particles can move in the opposite direction of where they are being pushed. That’s like pushing a ball forward and having it roll back towards you instead.
