Scientists may have finally caught “empty” space changing light

Scientists have found potential evidence of vacuum birefringence, a quantum effect where empty space alters light, by observing a magnetar. This phenomenon, predicted by Werner Heisenberg, occurs when strong magnetic fields cause virtual particles to influence light travel.
Why it matters
This discovery provides a rare opportunity to test quantum physics under extreme conditions that are impossible to replicate in Earth-based laboratories.
Nearly 90 years ago, Werner Heisenberg predicted a strange quantum effect known as vacuum birefringence, in which seemingly empty space can change the way light behaves. According to the idea, even a perfect vacuum is not truly empty. Instead, it should contain "virtual particles" that briefly appear and disappear.
