There are other forces in the Universe besides gravitation: for
example the Lorentz force, which can explain levitation.
Some examples of levitation:
Saturn's B ring spokes, electrostatic dust transport on the Moon:
"Dusty Phenomena in the Solar System", Sky&Telescope, pg. 61

(Thomas Gold has proposed electrostatic dust transport on Eros
too)
