Trickle-down is the solution (to the planetary core formation problem)

New research from The University of Texas at Austin adds new evidence to a theory that claims the metallic cores of rocky planets like Earth were formed when molten metal trapped between grains of silicate rock percolated to the center of the planet during its early formation.

Scientists have long pondered how rocky bodies in the solar system — including our own Earth — got their metal cores. According to research conducted by The University of Texas at Austin, evidence points to the downwards percolation of molten metal toward the center of the planet through tiny channels between grains of rock.
