Light in metric space-time and its deflection by the screw dislocation

Abstract

We derive the light deflection caused by the screw dislocation in space-time. Space-time is medium which can be deformed in such a way that its deformation is equivalent to the existence of metric which is equivalent to gravity. The existence of the screw dislocations in cosmology is hypothetically confirmed by observation of light bursts which can be interpreted as the annihilation of the giant screw dislocations with antidislocations. The origin of the gravitational bursts are analogical as the optical ones. They can be probably detected by LIGO, VIRGO, GEO, TAMA and so on. The dislocation theory of elementary particles is discussed.
