Dynamical equations exhibiting an anisotropic scaling between space 
and time admit a dispersive nature, as they contain higher-order spatial derivatives, 
but remain second order in time.

There are at least 100 billion brown dwarfs and planetary-mass objects in our Galaxy - objects that are not orbiting a star and have masses between that of Jupiter and of the lowest mass stars (~80 MJup). Several theories for their formation have been proposed, and could all as well be at work, but their relative importance is not known and is expected to vary with mass and environment.
