David Bohm and The Holographic Universe:




Brilliant minds have given the universe many names – “the Self-Aware Universe” (Amit Goswami), “the Magic Universe” (Nigel Calder), “the Looking Glass Universe” (John Briggs and David Peat), “the Conscious Universe” (Dean Radin), and “the Elegant Universe” (Brian Green). Scientists still speculate about parallel universes.
The underlying premise behind these various titles is the idea that at a deep level all things in the universe are... infinitely interconnected. If this sounds more like philosophy than science, remember that until relatively recently, people researching the natural world were called “natural philosophers” and the words “scientist” and “physicist” were coined by William Whewell, only in the 19th century. But let’s get to the title of this piece, the “holographic universe.”

What is a hologram?
A hologram is a three-dimensional photograph made with the aid of a laser. The word has Greek roots, “holos” meaning whole, and “gramma” meaning message. To make a hologram, a laser is used to illuminate the physical object. The second laser beam is bounced off the reflected light of the first and the interference pattern is captured on the recording medium. When the developed film is illuminated by another laser beam, a three-dimensional image of the photographed object appears.
The difference between an ordinary photograph and a hologram (apart from the way it’s made) is in the part/whole relationship. If you cut up a regular photograph into smaller pieces, you will end up with each piece as a separate part of the whole. You will need to use your jigsaw puzzle skills to put the picture together again in order to see the original image. But if you cut up the hologram into smaller parts, each part will contain a smaller, blurrier, but exact version of the whole picture.
How does this relate to the universe and David Bohm’s idea that it resembles a gigantic hologram?
