Light passing by an extremely spinning black hole splits: rays with left and right circular polarization fall to Earth in different hemispheres, at a distance of more than a trillion kilometers. This will allow astronomers to catch polarization signals and study these invisible giants.
🎯 A spinning black hole drags the very fabric of reality with it, like a giant whirlpool, and this splits light into left- and right-twisted rays.
🎬 In science fiction, such as in Star Trek, variable polarization is part of sensor systems. This same effect could inspire real methods for observing black holes.
