Cosmological model in the presence of cloud strings with electro- magnetic field in general theory of relativity. Exact solutions of field equations are obtained using the fact that shear scalar is proportional to scalar expansion and constant decelerating parameter which is derived from variation law of Hubble parameter proposed by Berman [1]. The dynamics and significance of physical parameters of the model are discussed using a graphical representation of these parameters. The physical and kinematical properties found in this model exhibit an accelerating expansion of the universe, which are compatible with current cosmological observations.

In this article, we have observed the Bianchi type-III anisotropic cosmological model in the presence of cloud strings in context of electro-magnetic field in general theory of relativity. With the aid of the constant decelerating parameter and the shear scalar's relationship to scalar expansion that is derived from variation law of Hubble parameter [1] exact solutions of field equations have been obtained. Graphical representations of the parameters have been made out for the analysis of the dynamics and significance of the physical parameters of the model. The physical and kinematical properties found in the model demonstrate acceleration in the expansion of the universe, showcasing a compatibility with present day cosmological observations.

This work investigates the dynamics of a collapsing magnetic string dust and string fluid in the Plank Era via spherically symmetric rainbow geometry. The field equations are modified and solved to obtain the dynamical quantities including mass density, pressure, string tension, and magnetic field strength. These quantities are presented graphically. The energy conditions are computed showing that all the dynamical quantities are associated with physical matter. The distance and moment of apparent horizon formation are computed. The magnetic field is found to affect the distance and moment of the apparent horizon's formation. It accelerates the collapsing process. Further, the dynamical variables are maximum in the collapsing configuration's center leading to compact object (black hole) formation. The probing particle's energy affects all the dynamical variables of the fluid in a direct proportion. This resolves the information paradox as a particle with greater energy grasps the information from a particle with lesser energy and takes it out in the real world.
