Frame dragging is a theory which says that space is elastic, and particles in it will exchange energy with it. In the scientific world, "elastic" means that when you apply a certain amount of force to an object (which will cause it to bend) and then remove the force, the object will return to its original shape and energy state. Also, space is referred to as spacetime, which is simply a way to bring together the concepts of space and time. This basically means that whenever space is affected, time is affected. Frame dragging would provide answers for very old questions about gravity, strong force, and wave-particle duality (how things like electrons can act like waves and particles at the same time).
