Very high velocities like velocity of light are observed in astronomical jets from the centres of many Galaxies including our own Milkyway. The formation of such high velocity jet is explained using SITA simulations in this paper. For this purpose the velocity attained by a test neutron in the path traced by it is calculated and depicted using a setup of 133 bodies. This setup consisting of one densemass of the mass equivalent to Galaxy center, 90 stars with similar masses of stars near Galaxy center, mass equivalents of 23 Globular Cluster groups, 16 Milkyway parts, Andromeda and Triangulum Galaxies at appropriate distances.

The velocity of particle attained in the path by this test neutron was found to be very high as observed in an astronomical jet emerging from Galaxy center. Dynamic Universe model can be used for such an application.

Wikipedia:
An astrophysical jet (hereafter 'jet') is a phenomenon often seen in astronomy, where streams of matter are emitted along the axis of rotation of a compact object. While it is still the subject of ongoing research to understand how jets are formed and powered, the two most often proposed origins are dynamic interactions within the accretion disk or a process from the central object (such as a black hole). When matter is emitted at speeds approaching the speed of light, these jets are called relativistic jets, because the effects of special relativity become important.
