Gravitational lenses could hold the key to better estimates of the expansion of the universe
SLAC cosmologists are using multiple images of the same quasars, produced by massive galaxies’ gravitational pull, to calibrate cosmic distances. Their work may help resolve long-standing debates about how quickly the universe is expanding.
Light from a distant quasar bends around a galaxy, creating four images of the quasar.
