I don't know that working backwards would have to be any harder, computationally speaking, except maybe for a computer that isn't designed for that kind of operation. When the frame of reference changes to "computing", we would probably look at "entropy and chaos" differently as well. Perhaps what is "entropy and chaos" in one direction is just evidence of randomized data, or "noise" that would make perfect sense in the other direction?
In the model, nothing must ever be lost because when the direction reverses, everything must return where it originally was else any missing 'data' could seriously crash the system, or at least cause a glitch or something that might completely throw out the operation during that particular cycle of work.
At any rate, from what I remember of the model, as 'computation' is done and there is a "carry" of sorts, the 'extra' unneeded data is temporarily stored elsewhere - perhaps encoded as a crop circle in a wheat field on a planet in the Orion system? :P
I admit I haven't got a full understanding of the "Bennett Machine" but I gathered the problem with "Reversible Computing" was that it isn't possible unless there is absolutely zero loss of energy in the computer system doing the work. Certainly, from God's perspective, there isn't any loss of energy/data, so theoretically, as you say, it should be possible to work backwards to the original state. In the example of flow calculation in a system studying fluid dynamics, I imagine that things quickly get beyond recoverable. Consider trying to work out an original state in water which has traveled a significant distance from the point of measurement. Like, out into the ocean where countless other forces are now adding their energy to the original water sample.
The C's talk about probability, and their own inability to predict with accuracy future states in chaotic systems, implying that even at 6th Density, whatever serve as computers aren't tough enough to tackle such problems with 100% accuracy. Interestingly, now when I consider things, it actually seems more reasonable to think that it is easier to work backwards exactly because we have hard records of what happened, but only if we take those records into account while reverse-computing the model. Starting with just the final state and trying to work backwards without the advantage of recorded history of a model's established progression is probably just as difficult as working forwards.

Very interesting. May I offer a comment or question or two?
Of course! That's why I'm posting. Working in a vacuum pretty much guarantees failure.
Woodsman said:1. We are all water molecules flowing down stream. Upstream is the Past, and downstream is the Future.
2. Jim, the time-traveling Water Molecule, gets into a little underwater rocket ship and travels downstream.
3. Jim travels for one day, his time, and then stops his rocket. The energy spent by the rocket allowed him to move faster downstream than the other water molecules around him, and so he winds up somewhere in their future.
4. In the future, all of Jim's friends are fifty days older while he has only aged one day.
You lost me on number 4. In that example, Jim is 50 days ahead of his friends, yet his friends are 50 days older?
I'm probably missing some of your background thoughts here. :)
Yes, the example is awkward. -More so than I realized when I first put it down.
To make it work, we would have to think of water molecules not as points traveling down the stream, but rather as threads which are not actually moving at all. Rather, the apparent flow of the river is the constantly advancing focal plane of attention which creates the perception of 'time'. (4th Density molecules, perhaps?) What Molecule Jim has done is jump his personal focal plane ahead by fifty days. It took him personally, one day to do this. The more I think about it, the more it seems that physical motion in our 3D reality may actually be the same as time travel! (We just don't notice it unless we are moving really, really fast.)
Woodsman said:Moving from one point to another in our 3D world takes 'time'. The beginning point and the ending point are a length of 'time' away from one another. Perhaps at close to the speed of light, our linear motion is actually noticeably out-pacing the speed at which the river of time flows. It doesn't matter what direction we pick, because all directions move forward in time, but the speed at which we cross space, any speed, directly adds to the speed at which we are already moving through 'time'.
If we increase our speed close to that of light, and time slows down and the amount of 'space' being crossed seems to speed up, doesn't that mean the entire system is shrinking? Perhaps at the point where the speed of light has been approached, the passage of time is barely even noticeable because the entire system is the relative size of something ready for another 'big bang'?
Well, the thing about relativity as I understand it is that to the traveler, everything always seems normal from his own reference point. Only the observer is able to measure time behaving differently.
Here's one which baked my brain when I first encountered it. . .
The speed of light, I discovered, is not actually a limit on speed. It's just a limit on what can be observed. That is. . .
1. You board a rocket ship and fly away from the Earth increasing your speed until you get close to the speed of light, the "universal speed limit".
2. You look out your window and see that you are approaching another planet which is apparently also moving at near to the speed of light in the same direction as you.
3. Relative to that planet you are not moving very fast at all. You decide to land.
4. You get out of your rocket ship, spend a week or two exploring. Everything seems normal and still. You refuel your rocket, collect supplies, etc.
5. You launch again, same direction as before, hit the boosters and again accelerate once more to near the speed of light, leaving the new planet far behind you.
6. So now, relative to the Earth you originally left, are you traveling at twice the speed of light?
I asked this question of an engineer who works with satellite technology and who needs to work relativity into his equations, and he told me that, yes, you ARE traveling at twice the speed of light, but you are no longer visible to the original planet Earth. Once you passed the speed of light, you have vanished into another state of being where no information can be passed between yourself and an observer on Earth.
So technically, we can have a whole other layer of reality, entire planets and galaxies existing right over top of us, but which we cannot see because they are traveling beyond the speed of light. We would also be invisible to them because no information can pass between our two realities.
This seemed reminiscent to me of 4th Density.
Neat, huh? :)
