Orientation entanglement means that two particles are linked in a way so that knowing the orientation of the first particle automatically tells you the orientation of the second particle. Imagine you have two hands, a right hand and a left hand. If your right hand is up, we automatically know that your left hand is down. The same thing happens with particles - if one particle has a certain orientation, we automatically know the orientation of the other particle. This happens because the two particles are entangled, which means they are connected in a special way that we don't fully understand yet. Scientists are still studying this phenomenon to better understand how it works and how it might be useful in the future.
