Gravity and Repulsion

When an object falls to the Earth, it will often smash, leaving an imprint on the ground.  On the other hand, when two liquids are placed in the same location, e. g. a beaker, they will sometimes combine to form a different liquid.  The contrast demonstrates that a gravitational field is only relatively attractive, and involves relative impenetrability.  In other words, a gravitational field involves repulsive forces.  Hence, the widely-held thesis that 'Gravity involves no Repulsion, and only Attraction' is inaccurate, at best.  Accordingly, any denial of the universality of Repulsion, on the basis of the absence of repulsive forces in a gravitational field, is ungrounded.
