Classical holography uses coherent light, which is nothing more than a bundle of photons whose waves have the same frequency and are in the same phase. The light beam is divided into two parts, the so-called reference beam, which falls directly on the detector (photographic plate) and the illumination or object beam, which is reflected from the observed object and then also goes to the detector. The object beam carries information about both the light intensity and its phase, which enables the three-dimensional nature of the object to be captured in the hologram. The interference of both of these rays on the photographic film then creates a resulting flat (two-dimensional) image that appears as if it had three dimensions.

If we take into account that collisions of photons can also create three-dimensional holograms under certain circumstances, the theory that the Universe works as a virtual simulator seems increasingly likely. In it, our invisible thoughts and ideas (images in the head) are transformed into perceptible objects (things and events) and thus an environment (scenery) is created for the unfolding of an infinite number of cosmic events. Similar to how a computer turns a programmer's ideas into two-dimensional images, the Universe turns our thoughts into three-dimensional holographic forms, which we then perceive and experience with our senses. So bear in mind that we can change reality with our thoughts, let's therefore make the most of this opportunity...
