From a distant star,
Magnetar’s field whispers truth—
Light bends through the void.
Magnetar’s field whispers truth—
Light bends through the void.
A magnetar’s colossal magnetic field may have revealed a quantum effect predicted by Werner Heisenberg nearly 90 years ago, in which seemingly empty space alters the behavior of light. If confirmed, the discovery could offer the first direct evidence of vacuum birefringence and open a…
