Cosmic strings - How One Galaxy can appear as two?

Cosmic strings are not new to cosmology. But of late they became very sensational. It may be defined as one of abundant very extensive and thin variations or topological defects in space conjectured to have resulted from the Big Bang and to have made potential the hodgepodge of mass into constructions like galaxies and the unequal distribution of mass in the universe. A cosmic string is an imaginary one dimensional topological imperfection in the basics of space-time. A hot detection of a double galaxy has some interesting insinuation for cosmic string theory. In an article entitled CSL-1: chance projection effect or serendipitous discovery of a gravitational lens induced by a cosmic string? published in August 2003 in Volume 343, Issue 2 of Monthly Notices of the Royal Astronomical Society, a scientific faction led by Mikhail Sazhin reported the ‘chance discovery’ of two apparently matching galaxies very close together .
