Quantum mechanics with wavefunction collapse is an irreversible computation. But irreversible computing takes extra energy. So the universe computation must be reversible. And in fact, the irreversible universe is embedded in a larger computation, the multiverse, where no information is lost.
I have a hunch that this is a theorem that could be proven, and perhaps it has been proven already (please send link if you know of a proof).
If this is the case all information lost in the universe is still out there in the multiverse, and we can do Quantum Archaeology if we find a way to mine it.
I like your argument re: energy.
Fun article.
A shadow world...MWT says there aren't shadow worlds but actually parallel worlds piled on top of one another where every possible event happens.
They fork like trees branches, splitting into thinner & thinner superpositions.
The issue for me is evidence. Although superposition of states looks
unchallengeable I dont really believe it because it's not what I observe!
The two schools both believe it though. Penrose told me there are infinite infinities before the collapse and MC Price (Many Worlds Theory FAQ) with whom I was listening to Penrose lecture on geometry told me the collapse in MWT is near infinite worlds splitting (so many you can say they're infinite).
The both agree on a superposition.
The sole evidence for this was the slit photon experiment.
However now there's also quantum computers that utilise super-positions, so to hell with my thoughts.
So both the Copenhagen school and the Everett school agree there are zillion worlds...even for a split second.
I dont know what a superposition is except what's stated by MWT (there's a lively discussion/modification on wiki Many Worlds Interpretation page BTW)
& it's probably best for me to pass on science discussions except in top level ideas.
I'm focusing on recreating any given human being and Many Worlds Theory (Multiverse pretty much) says there's no way back after the collapse.
Histories decohere.
However finding information and configuring information by Cause and Effect by brute force are massively different.
I dont expect to find anything.
But I do expect history can be calculated by statistical reconstruction with classical rules.
Tipler in the event you took part in said correctly that we have Newtonian physics again.
The reason is that Many World Theory has returned it to determinism as it resolves every paradox in QM.
An event in the present doesn't exist in isolation but is the result of its ancestor events in the past (it's timeline).
Figuring out that timeline is MUCH easier than it might seem, although it relies on:
a. enough raw processing power
b. enough mathematics:
i. to retrodict down timelines
ii. to construct checkpoints
iii. to do MANY other things for making maps out.

The METHOD is what interests me, & specifically for resurrection. I see it as forensics.
Re ENTROPY PDCO----
My superposition on that is that I'm not bright enough to worry about it (i did in my youth) but I'll wait until Superintelligence figures it.
I suspect we dont understand a fraction of the cosmos and that the universe is limitless and therefore undefinable.
PDCO wrotre:
You’re not looking for blips and abnormalities. You’re looking for brain configurations (like you say, only configurations that work but there are plenty of those). You have certain cross-references, and yes, these can enable you to greatly reduce the number of permutations, but you will still be left with zillions of permutations. You can’t narrow it down to one history. Even SetAI agrees with this !
Let me be clear Old Man....
I believe Quantum Archaeology can be achieved by classical theory.
Further that as General relativity and quantum mechanics are in conflict one or both must be wrong and certainly they need a resolution.
Thus it is IMPOSSIBLE you could have identical situations.
That would invalidate the carefully constructed space-time MATRIX full of checkpoints which I anticipate would be constructed.
I wonder if you muddle common history with many histories?
Before world have split there is a common history, but that would describe the event you want PERFECTLY.
I believe it is possible to draw up an archaeological matrix as good as the periodic table.
And to describe the laws of the cosmos in a similar detail,
and they will have elegance precision and perfection like the Wittelsbach Diamond.
In fact I challenge you to nick it and examine its symmetry.
