I'm going to stick with simulation because other peoples' uninformed questions about who or what is controlling it or them should not affect the model. It's pretty obvious that each person controls themselves.
Don't underestimate the reluctance of people towards theories because of "badly chosen wording".
But putting this aside, I really think "simulation" is actually wrong. First sentence about simulation at wikipedia:
Simulation is the imitation of the operation of a real-world process or system over time.Imitation of a real world process.
That's were I see a major problem. There simply is no need to add this layer of unknown, unproven (and imho false) assumption.
same for "computer simulation":
A computer simulation (or "sim") is an attempt to model a real-life or hypothetical situation on a computer so that it can be studied to see how the system worksto be studied, model a real-life situation on a computer...
it's not just that people think like I described, it is a logical consequence of the definition of the used terms.
If (as youhn points out as well) it is the actual universe itself, computing itself, iterating as a huge fractal feedback-system, there is no need for the terms.
But I don't want to overly harp on about this
Have you read into Zuses Calculating Space? I'd love to hear your opinion on it and where you see parallels/differences to your theory.
As for the answer to those questions, it's most likely humans of the future who develop the simulation, as stated in the description. The physics of the universe within the sim remain unchangeable, the physics cannot be manipulated. It could not properly proceed otherwise.
--as stated in what description?--
Hm. And these humans of the future were the first simulators? so what is their universe made of?
what about causality?
what do you see as evidence for this?
(don't get me wrong, I like many parts of your ideas and deliberately pick the parts where I think there's open questions)
Your inter-universal conscious is an electromagnetic field using your physical body as an avatar and that field is serving as an avatar for the extra-universal conscious....an electromagnetic field that is YOU. But the extra-universal you has access to the infinite and thus can access infinite possible options. This brings the CONCEPT of infinity into the physical universe but not the actual OCCURRENCE of infinity.
Nice image.
Reminds me of talks about psychedelic experiences and the concept of entheogenic substances as a "shortcut" to to this "extra universal you".
Too bad that the topic is stigmatized and usually not discussed or studied without restrictions or drifting into illegality.
I found the short book "Being Human" by Martin Ball very insightful on this. Recommended read!
For instance, the famous "particle in a box" - if we do that calculation and make our box larger and larger, at infinity the quantization just disappears. Similarly, for a hydrogen atom, higher and higher energy states of a bound electron lie closer and closer together until they essentially behave classically. Once the electron has too much energy, it isn't bound at all any longer and resumes a continuous (though inherently imprecisely measurable) path.
The universe appears to be (but the debate isn't entirely settled) entirely unbounded. "Boundaries at infinity", as would be required for such a setting, don't have any effect at all on any close state. No quantization, no "voxelized" space-time.
If I understand that correctly the fractal view I described above regarding finite vs. infinite both being present in a fractal fits in there.
When you hear "fundamentally smallest scale" you shouldn't think of digital cameras with their fixed pixel-wise resolution but rather of the effective resolution that the cameras' optics will produce. There are no sharp jumps but rather any smaller details are completely washed out.
That is kind of what I mean. Using the term voxels in the initial post was misleading and just playiong around with numbers.
Our perception of the world seems quantized when looking very closely. extreme example: long exposures of hubble deep field, with just a few single photons arriving from whole galaxies
But that is just our perception, our current frame of reference. Our camera as you say.
The whole post was a good read, but this was a kind of aha-moment for me. This would mean smaller things than the planck length can exists, if I understand it correctly.
Yes, but not within our frame of reference, they are out of reach. (if
I understand correctly).
How does time scale at these "zoom depths"? Do we have to look at smaller and smaller timeframes, in order to observe smaller and smaller sizes?
It's linked, the smaller the space the smaller the time intervals involved.
In general I don't really like the idea of the universe being a simulation. At the same time I do have some sentimental feeling for digital physics, but I do not believe the world is strictly digital as in 0 and 1 (or similar ON, OFF).
As written above, I think reality itself, the "big picture" might not be quantized into 0 and 1, but our perception of reality is. A single photon reaches you or it doesn't. That tiny spot in hubbles deepfield exists, or it doesn't. At least from your perspective.
Another angle. How would dark energy and dark matter look at the very small scales?
Even more than gravity, dark energy has no significant impact on small scales. Even within neighbouring galaxies it is too small too measure.
There is no separation between the computer, the program, the input and the output. The world computes itself from the initial state to whatever the logic of the smallest parts drives it to.
Wholeheartedly agree!
and to add a little more confusion: Would this make the universe deterministic? every action and each of your own decisions predestined from the initial conditions?
i personally don't think so and think this is connected to heisenbergs uncertainty principle. minute (and impossible to measure) differences at the "smallest" scales will blow up to a totally diffferent end result.
..
damn. these posts always get so long. now howard posted even more regarding my terminology problems.
I therefore propose that the term, "mainstream science", be replaced by, "prevailing psycho-social mindset of empiricism".
As much as I would like to have an alternative to "mainstream science", "prevailing psycho-social mindset of empiricism" might be correct, but soo un-catchy that it won't be used for sure. I have a hard time remembering it longer then 5 minutes
Sorry, I don't have a better idea.
there can be no condition that exists where "not universe" is possible.
says who?
As I understand the concepts, multiverse and also the big bang theory have "not universe" embedded.
It's just not used often, because it makes little sense to speculate about something that we (very probably) will never be able to falsify.
The arbitrary and unwarranted restrictive effect of that specific mindset is well illustrated by the following. Note how its persistence derailed open-minded exploration and has led to ever greater explanatory convolutions in order to avoid the obvious even as observational evidence accumulates which demands consideration of "not universe" as a rational component of the entirety of reality.
"In the 1920s, theoretical physicists, most notably Albert Einstein, considered the possibility of a cyclic model for the universe as an (everlasting) alternative to the model of an expanding universe. However, work by Richard C. Tolman in 1934 showed that these early attempts failed because of the cyclic problem:
according to the Second Law of Thermodynamics, entropy can only increase.[1] This implies that successive cycles grow longer and larger. Extrapolating back in time, cycles before the present one become shorter and smaller culminating again in a Big Bang and thus not replacing it. This puzzling situation remained for many decades until the early 21st century when the recently discovered dark energy component provided new hope for a consistent cyclic cosmology.
I just have to throw in the bifurcation diagram here again, because it fits the "cyclic" universe idea so well. except that it's cycles of growing complexity, as with shapestacking in the mandelbrot-set.
phew. so much for today.
