i got gemini to agree that if we took every particle in the universe and precisely made it an antiparticle with precisely negated charge, position, and momentum, that the progression of the history of the universe would then precisely flow backward. (of course the transformation of information to high precision in such a scenario is so far beyond astronomical as for that to be in the realm of impossibility even for me to consider)
then i got into a space of confusion again. i asked it to imagine a futuristic pod that could provide a precise high entropy environment for an antimatter agent inside the pod to have a logical experience of time flowing backwards (a simulation of a reversed system [[and asked
so, and now i sound like gemini, such a pod differs from a time machine in that it is more a way to expend incredibly huge amounts of energy in order to orchestrate that antimatter display its properties of acting as if time were reversed. but there's no expectation that this pod would exist prior to its creation for example or after any point in time where the state of its observable environment couldn't be precisely predicted from the past. we could try to expand such a pod to the idea of a time machine but it's quite limited as is and not intended to be one at this time. notably it's not reasonable to produce that environment of states, it's much much harder than unburning a fire by mapping the path of every particle from it.
it how it might process light ...
this is where i am at trying to read its long reply:
Is the pod showing the agent images of the external world by controlling photons? If the pod is projecting images for the agent to see, then: Agent's View (τ): The pod's projector (an anti-projector, presumably) emits photons (in the agent's τ forward time). These photons form an image on the agent's "retina." Normal. Our View (t): The pod's "anti-projector" would appear to us to be absorbing photons that are converging on it in a highly specific pattern (the image). This is the "time-reversed emission" we discussed. The pod would need to be an incredibly sophisticated "photon collector" to achieve this if it's showing images of our external world in a way that makes sense for the agent's reversed time.
i'm maybe 1/3rd through the above. i'm excited that it talks about photons appearing absorbed vs emitted because earlier in its reply it assumed the anticamera processed received photons from the sun which doesn't seem to make sense to me.
This idea of some time travel agent being stuck in a world of non-anti-matter where everything behaves _so_ backwards that -- -- anyway, it seems conceptually very similar to being inside karl! where part of karl tries to do A at the same time as other part tries to do ~A and it exhausts energy to maintain harsh disparate adjacency everywhere. crossing border just doesn't work, but there it is, a world of opposites
