The path of light from a lamp to a camera is usually the same in both directions. But near a rotating black hole with a preferred direction in space, this isn't the case. If you swap the light source and the observer, the black hole's shadow transforms from an oval into a teardrop, as if in a one-wa

Physicists have discovered that under environmental influence, a strong quantum bond between particles breaks down faster than a weak one. The reason is excess energy in highly entangled states. This counterintuitive effect helps manage fragile quantum systems.
