'''Gravitational lensing''' is a gravitational-optical effect whereby a background object like a distant [[quasar]] is magnified, distorted and brightened by a foreground [[galaxy|galaxies]]. An intervening concentration of [[matter]] is declared to bring 'focusing' effect so that even objects normally beyond [[Scientific observation|observational]] distance can bee seen by [[astronomer]]s at the [[Earth]]. It is alleged that, for example, the [[galaxy cluster]] Abell 2218, distorts and magnifies light from galaxies behind it.<ref>{{cite web
