A distant supernova appeared to explode twice, baffling astronomers. This cosmic event was explained by Einstein's theory of general relativity. Gravity bends light, causing it to take different paths. This phenomenon, called gravitational lensing, allowed scientists to see the same explosion at different times. The reappearance confirmed theories about gravity and dark matter distribution.
