If we as humans could not see, feel, or hear the universe would only be partials. In this universe particles cannot be created or destroyed. We are made entirely of patricles, all particles have been around since the existence of this universe. Our make up is as old as the universe.
Now going one step farther, the partials of this universe creates waves as they move. We see these waves as light and hear these waves as sound. We also feel these waves and this is how we know the universe. The universe as we know has been created within our collective minds.
