Gravitational waves are disturbances in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light. They were proposed by Henri Poincaré in 1905 and subsequently predicted in 1916 by Albert Einstein on the basis of his general theory of relativity. Gravitational waves transport energy as gravitational radiation, a form of radiant energy similar to electromagnetic radiation.
What this does is harness that to project a wave out from you the listener during the duration of your listening to this, spreading it throughout the earth and universe.
A small thing like this can lead to big changes later on.
The personal effects for you also can be profound on a spiritual level.
It may also attract the attention of higher vibrational beings,
*More explanation, due to all the questions, I realize now this was too over the top*
You become the center of a wave, you are like a ball bouncing in the ocean of spacetime and the ripples you are sending out affects the world around you and universe at large over time.
It works toward helping change you and the world/ collective consciousness by propagating a bit of love to the general experience of life on this dimension.
(it is not meant to grant you wishes or petition your cause amongst other beings, its just that it may be when you do larger things like this, your presence is noticed more)
