Frame-dragging
Scientists such as Einstein and Schrödinger spent much of their lives trying to find an answer for how something like an electron can act like a wave and also act like a particle. Frame dragging states that since spacetime is elastic, it can also give the spin-energy back to the particle. Once the particle has all of  its spin-energy given back to it, it acts most like a wave. At that point, it will once again begin using its energy bunching up spacetime. Once the particle is no longer spinning, it acts most like a particle. Then, spacetime begins giving the particle its energy back, and the cycle continues forever. This is how a particle can actually act like a particle and a wave at nearly the same time. No energy is lost during the cycle due to the conservation of energy.
