“…The M theory stars are eleven dimensional and are assumed to be made up of N stacks of M2 and M5 branes, intersecting according to the BPS rules whereby two stacks of five branes intersect along three common spatial directions; a stack each of two branes and five branes intersect along one common spatial direction; and two stacks of two branes intersect along zero common spatial direction. Assuming the spatial directions of the brane worldvolumes to be toroidal and assuming necessary isometries, the intersecting M theory branes can be described by N seperately conserved energy momentum tensors T M N (I) , I = 1, 2, · · · , N , with appropriate equations of state among their components [55,59,60,61,56,57,58,63,64,65].…”
