But astronomers say the true nature of a double quasar may shed light on the question.
The double quasar Q2345+007 has intrigued scientists since its 1982 discovery.
But now astronomers using data from three telescopes have examined the double quasar and its surroundings with a sensitivity unmatched by surveys anyplace else in the sky.

About 80 gravitationally lensed quasars are known, but the record separation of the Double Quasar (6.

Since the late 1980s, though, researchers have found about 100 double quasars
