The universe has got to be analog. Digital is a human way of encoding signals. Light is analog, and it can be recorded using analog means (like silver halide emulsions on film) or using digital means (CCD and CMOS sensors which perform an analog-digital conversion). Sound is the same. One would have to imagine that the fundamental forces in nature, like gravity and like nuclear forces are analog as well.

I'm no expert on the subject but however, I would class analogue as just encoding signals in a manual form. I.e the turning of levers rather then the pressing of buttons.

I would class such things as light, and elements as Quantum, again something which could be classed as coding, just on the quantum level. A natural coding. Quantum Physics, is just the undetermined coding of atoms and particles.

But this might just be me babbling at an already proven theory or something.

Digital = number-ish (digit)
Analog = Like, or resemblance (sometimes continuous)
Quantum = Existing only in a certain subsets of numeric states, and never in between these states.

In the context of recording:

Analog means that the recording is continuous (down to the level of the recording media anyway. A groove in a vinyl disk for example, or a variable strength magnetic field in a metal impregnated tape.) Digital recordings, by contrast, store only one value per a given interval, in other words digital recordings are "chunky".

One way to visualize it; Say you record a sound wave on a piece of graph paper using a pen. The analog recording would be a continuous curve, while the digital recording would look more like a line of steps going up and down that approximates the analog version.

(As an aside; in practice there is no such thing as an analog recording, all recordings are digital if you look closely enough.)
----------------------------
The idea of a digital universe (as I understand it) speculates that at a small enough scale all measurements are in discreet units. This conjecture comes from quantum physics in which time and space are both quantized below a certain boundary (Planck length, Planck time, named for Max Planck)

Is the universe like this? The essential question is whether or not space and time come only in quanta, or if that's only a property of energy/mater. The math indicates that space-time is quantized. Unfortunately for the analog universe though quantum physics' mathematical prophecies have a habit of being confirmed as reality.
---------------------------
This quantum nature that quantum physics requires conflicts with relativity, another very strong well supported theory, causing aggravation for the Grand Unified Theory (GUT) seeking types.

I always thought of the digital universe as stated, or more precisely a universe where all values- from weight to depth to color, position, nutrients, are all reduced to a single data system of waves or maybe discrete values like a digital audio signal. All perceived reality can be different for animals depending on how they convert, via their sense organs (conversion analogues), the universe-value 'data'.

We have a dominant sense which 'maps' the data into an explorable map, the eyes is ours like the ears are the bats. We use texture to define territorial boundaries like fences, walls etc. where as cats use scent.

I see the universe as digital because if I think of digital I think of binary, thus 1's and 0's which are opposites. That sort of connotes to perception theory right? How there are two sides to everything.
If I look at the entirety of the universe then I can see it as analog, but I really can't give any reason to back that one up.

The earth, more or less, is spherical. How are there two sides to that?

Maybe there are only two sides to a single perception of something, but when perceiving the entirety entirely, the Earth as a whole, there is no opposite in existence.
Like a matter Earth and an anti matter Earth: as perceived through state of matter.

Inside and outside?

Dark side, light side?

Analog can't connote to opposites, therefore the only analogous system or whatever u may call it is the entire universe, the infinite, everything. The finite parts are digital. So the universe is both analog and digital. What I want to know is where does quantum come in?

Up-side, down-side?
Have we slipped through a hole in the 'box' or are we just pushing the 'wall' a bit?
*__-

Well if there was one grand divide of earth, now that I think about it, I don't think it would be manifested on the surface of the earth but in the complex structure of nature, something more general maybe like life/death.

I guess in that respect we are pushing the walls, or at least leaning on them, hard to gague the scale of the 'divide'.

p.s. Is dichotomy the right word to be using here instead of divide?

Dan.

Agreed -- something fundamental and intrinsic.
