What we didn’t discuss yet is that a single piece of holographic film is capable of storing many, many objects, and in fact holography may soon replace other laser-based storage techniques because of its capacity to hold so much information. (“The advantage of this type of data storage is that the volume of the recording media is used instead of just the surface.”4)
Which object or objects pop out when you direct a reference beam at the film depends on the angle of the reference beam. In other words, you can choose which holographic images to create by using different angles for the reference beam to select the exact wave patterns you want that are stored in the holographic film.
Now let’s apply that to our holographic universe….
