The Universe is a Hologram
Well, it's official folks, we don't actually exist...

Re: The Universe is a Hologram
It deals with proving the holographic principle, a branch of string theory.

I knew it all along!

Re: The Universe is a Hologram
The way holograms work is light waves overlap. Where the two waves overlap constructively (hills on hills and troughs on troughs) you see something. Where the two waves overlap destructively (Hills on troughs) you see nothing.
All matter in the universe is actually a wave. Electrons and atoms and even molecules and therefore ourselves are actually waves (electron microscopes only work because electrons are waves). In the case of ourselves, our wavelength is so short we never observe ourselves diffracting (unless we get really drunk). One unresolved question is whether the universe is continuous or grainy on the planck scale. If in fact space is grainy on the planck scale then its possible that all the matter in the universe, which is all waves, would have its "peak" and "trough" at a particular planck point (at least any specific piece of matter would have its peak at a specific planck point). But what if the point the "peak" occurs jumps around slightly so that at one instant its on one planck location, but at the next instant the peak is actually at a nearby planck location? Those two waves representing the same object wouldn't then quite give 100% constructive interference, they would only give 99.99999999999999999999999999999999999999999999999 % constructive interference. That's what I would refer to as holographic noise (based upon what the article discusses). This is complete supposition on my part from knowing how holograms work, and from reading the article, especially the end paragraph. Last edited by Disillusioned_1; 11-04-2009 at 06:38 PM. |

Re: The Universe is a Hologram
Thank you. That made a lot more sense than the wikipedia entry.

Re: The Universe is a Hologram
I'm going to take a stab at this...
Your computer is made up of matter and energy. But without the information that makes it all work together, it remains as just a meaningless jumble of matter and energy. As per above, energy & matter are just incidentals, the key is the information that instructs all the matter and energy on how to organize itself. Without that information the universe is nothing, just like your computer would be nothing without the code. errr... does that make any sense... it sort of suggests design?? Andrew

Actually no. What you linked to is Einsteins theory, and how light can be bent by gravitation. That has nothing to do with planck-scale graininess or whether the universe is holographic in some manner. |

Re: The Universe is a Hologram
The analogy between a computer hardware and computer software and the universe is horrible, imo. I'm assuming he's suggesting that the matter in the universe is the hardware and the physics laws of the universe are the software.
If so, the analogy is horrible because if I delete all of the software on a computer, the computer still sits there physically unchanged. If I delete all of the laws of the universe, matter flies apart, atoms self destruct, etc. In other words the universe would be completely changed. The physical laws of the universe aren't merely a convenient program. The laws of the universe are what makes the universe possible as we know it. They're intimately entangled unlike computer hardware and software. |

This is what holograms do. The information for the hologram (typically) is stored on a 2-dimensional plate. When the plate is hit with lightwaves, the 2-dimensional information is perceived as being 3-dimensional. The main difference between a hologram and a photograph is that intensity, wavelength and phase information are all contained in a hologram and only intensity and wavelength are contained in a photograph. The phase information gives a hologram the appearance of being a 3-dimensional picture even though its not. As to how the universe could be a hologram, some redefining would have to take place because holograms are phase information of something you can't touch (light), whereas actual matter is something you can touch. It probably still works as an analogy because physical matter all has a wavelength so is in some sense all waves just like light is. I found the wikipedia article on string theory holography to be a bit baffling personally. |
