The zero-point represents the point of the lowest level of energy of our physical world, as is observed at “absolute zero” (-273o C). Here, all atoms exist at their ground states with minimal kinetic energy. Yet, there are still forces and fields at play that maintain the nature of the atoms. These fundamental forces are thrown into a category called “zero-point energy” that exists in the what is called the quantum field or quantum vacuum.
What we think of as empty space is not actually empty. It is teaming with the building blocks of everything that was, is, and will be. The energy of the quantum vacuum is a balanced composite of essential energetic building blocks and potentials that spontaneously pop into and out of our earthly existence of linear time and 3D space. They exist within a context of “fields” or contextual frameworks that most likely includes consciousness itself.
What we typically view as unchanging physical matter may actually be continuously passing back and forth from our 3D reality to and from the quantum vacuum fields, ordered by higher level consciousness; it is just that we do not yet have the tools/instruments to allow us to directly measure/observe it happening directly.
