You amplify gravity and pulsate the force outwards in a 10-foot-radius sphere centered on yourself. When you cast this spell, all objects that weigh less than 10 pounds that aren't anchored or weighted down within the radius are pushed outwards, directly away from you, and tumble to the edge of the sphere's radius.

Any creature within the sphere must spend 2 feet of movement for every 1 foot it moves when moving towards you. A medium or smaller creature that enters the radius for the first time on its turn or starts its turn within the area must make a Strength saving throw against your spell DC. On a fail, the creature is pushed outwards to the edge of the sphere and its movement speed is reduced by twice the distance it was pushed until the start of its next turn. On a success, the creature is not pushed.
