Life on -Holodeck






It is obvious to most of us that our feelings of love, hunger, anger, and so on, are internal realities, and the sound of an orchestra playing, the heat of the sun, the smell of bread baking, and so on, are external realities. It is not so clear how our brains enable us to distinguish between the two. For example, Karl H. Pribram points out that when we look at a person, the image of the person is really on the surface of our retinas. Yet we do not perceive the person as being on our retinas. We perceive them as being in the “world-out-there”. Similarly, when we stub our toe we experience the pain in our toe. But the pain is not really in our toe. It is actually a neurophysiological process taking place somewhere in our brain. How then is our brain able to take the multitude of neurophysiological processes that manifest as our experience, all of which are internal, and fool us into thinking that some are internal and some are located beyond the confines of our gray matter? Creating the illusion that things are located where they are not is the quintessential feature of the hologram. Physicist Nick Herbert, a supporter of this theory, says that this has sometimes caused him to imagine that behind his back the world is always ‘a radically ambiguous and ceaselessly flowing quantum soup’. But whenever he turns around and tries to see the soup, his clank instantly freezes it and turns it back into ordinary reality. Humans can never experience the true texture of quantum reality, because everything we touch turns into matter.

This clip is from Star Trek: The Next Generation(Episode 16, 11001001). Since the Starship Enterprise was traveling around the universe all the time, they had to figure out how to make it possible for the crew to take a vacation. So they created the Holodeck – a room where any hologram could be requested and created for their relaxation and enjoyment. The scene you will watch is Commander Riker asking to spend time in New Orleans playing some jazz, with a very interesting audience. Notice how surprised he is that the woman looks and feels and smells so real. But if all of this is possible, the question then arises: How is our holographic universe created for us to experience as the physical universe?
