Surprisingly the combination of few laser beams may generate an attractive long-range interaction within the Bose-Einstein condestate due to the interplay between dipole-dipole forces [1]. This is equivalent to gravity forces with an enormously large modeled gravitational constant. We solve the complete 3-dimensional Gross-Pitaevskii equation describing the system. Nondispersing structures of the condensate are observed numerically without the external trap for soft-core model potentials as quantum pressures are balanced by the self-interaction.
