  Close to equilibrium, the underlying symmetries of a system determine its
possible universal behavior. Far from equilibrium, however, different universal
phenomena associated with the existence of multiple non-thermal fixed points
can be realized for given microscopic symmetries. Here, we study this
phenomenon using a quasi-one-dimensional spinor Bose-Einstein condensate. We
prepare two different initial conditions and observe two distinct universal
scaling dynamics with different exponents. Measurements of the complex-valued
order parameter with spatial resolution allow us to characterize the
phase-amplitude excitations for the two scenarios. Our study provides new
insights into the phenomenon of universal dynamics far from equilibrium and
opens a path towards mapping out the associated basins of non-thermal fixed
points.
