Resumen de Warning light
Clark examines how the strange signals traveling from distant galaxies hint at turbulence for Albert Einstein's theory of space-time. If the observations are confirmed and they are controversial, they suggest that the landscape of reality is altogether more rugged than Einstein thought. That would mean his isn't the last word on space-time or gravity, and would change people's perception of the universe fundamentally. Before Einstein, space and time were thought to be separate properties of the universe.
