Even light gets it wrong: magnetars' ultra-strong magnetic fields force photons off a straight path. This shifts our size measurements of neutron stars by a full 10%—and holds the key to unlocking the mysteries of ultra-dense matter.

🎯 A magnetar with a 10¹⁵ G field can demagnetize all bank cards within 100,000 km—a quarter of the way to the Moon.
