| The moving cosmic string would have acted as an additional gravitational lens, affecting both quasar images simultaneously. |
| If the quasar results are eventually confirmed, our concepts of space and time are sure to undergo radical transformations. |
| In essence the galaxy is eclipsing the quasar, but paradoxically its gravitational lens effect brightens the light received from the latter. |
| At those rates, each galaxy could easily have formed the quasar and its black hole power source in just a few hundred million years. |
| On their way to Earth, the X-rays from a distant quasar dim as they pass through a cloud of the intergalactic gas. |
| Meanwhile, optical measurements suggest the quasar is a billion times more massive than our sun. |
