Taking a Dim View

One winter night in 1969, during an look-out atop Kitt Peak in Arizona, Michael Disney had a humorous thought. As he peered into a huge, superluminous galaxy, he wondered: What if an visitor astronomer there were staring right back? At a eyepiece of a possess telescope, a intelligent supernatural competence further be ogling Disney’s smaller, fainter home galaxy, a Milky Way.

Then another suspicion cut by a whimsy. The immature Welsh astronomer satisfied a visitor had no possibility of saying a Milky Way, let alone a universe’s oodles of dimmer galaxies. Overwhelmed by a glisten of all a stars pressed into a proprietor galaxy, a visitor would unknowingly be blinded to many of a cosmos.

Disney wondered if we competence be likewise deceived, awash in a inevitable heat of a possess surroundings. “It occurred to me there could be a whole star adult there of dark galaxies, only a small dimmer than those we can detect from Earth,” says Disney, an emeritus highbrow during Cardiff University in Wales.

Since that explanation in a dried scarcely a half-century ago, Disney, now 80, has searched for a shade galactic realm. His camber gained movement in a 1980s and 1990s, though during a spin of a century, a route ran cold. Disheartened and defeated, Disney relinquished a hunt.
