  It does make a couple of assumptions on the universe that seem strange.
Firstly in general you need gravity to get convection.  The hot, light
fluid elements rises and expands while the dense, cold elements fall
down.  Thus you need to assume either a global direction in which
gravity is pointing in the universe, or you need to assume that the
universe has a center of mass, and thus gravity.  Neither one of these
assumptions is supported by any existing observations, and both are in
conflict with the cosmological principle, which says that there
is nothing special with our position in the universe.  Essentially the
universe looks the same from all points in the universe, which
means that the convection currents will not know in which
direction they should go.
