The continuation of consciousness

The origins of the imperative, "know thyself", are lost in the sands of time, but the age-old examination of human consciousness continues here.

Meno, I'm sorry, it was Feynman who said that; not Planck.

From ... a-receiver

Richard Feynman's PhD thesis was about just this topic, if I am understanding your question rightly. Here is an earlier question about Feynman's thesis that addresses some of the fascinating issues involved with this.

At the suggestion of his thesis adviser John Wheeler, Feynman explained photon emission as a two-way interaction in which the regular photon is emitted and follows the "retarded" solutions to Maxwell's equations. "Meanwhile" (in some rather abstract sense of the word indeed) a target atom or particle in the distant future emits its own photon, but a very special one that travels backwards in time -- a type of solution to Maxwell's equations that had been recognized since Maxwell's time but had been ignored. These solutions were called the "advanced" solutions. This advanced photon travels back in time and "just happens" to arrive at the source at the exact instant when the regular photon is emitted, causing the emitting atom to be kicked backwards a tiny bit.

Amazingly, Wheeler and Feynman were able to write a series of papers showing that despite how mind-boggling this scenario sounded, it did not result in violations of causality, and it did provide a highly effective model of electron-photon interactions. From this start, and with some important changes, Feynman eventually produced his Feynman-diagram explanation of quantum electrodynamics, or QED. The curious time relationship continue in Feynman's QED, where for example a positron or anti-electron simply become an ordinary electron traveling backwards in time.

Staying fully consistent with his own ideas, Feynman himself described photon interactions as always having an emission and a reception event, no matter how far apart those events occur in ordinary time. In his view, if you shone a flashlight into deep space, the photons could not even be emitted until they found their "partner" advanced photon emission events somewhere in the distant future. The proof of it is in the very slight push back on your hand that happens when you shine the light, that kick coming from the advanced photons arriving from that distant point in the future and nudging the electrons in your flashlight filament.

If that is true, then light doesn't plow into nothingness eternally and that seems to support my circularity theory of the universe folding into itself so that if one could travel a straight line long enough, he'd eventually reach the point he started.. or at least some point where there are "things" to receive photons instead of forever travelling through nothingness with no possible destination.

Two objects can be in the same place, but not at the same time, and as logical as that sounds, I'm not sure what law insists it be so: are absurdities objectively illegal or an artifact of how this universe is put together?

I guess so but if so, it would have to be hidden from our consciousness because else we would not even believe or be able to make out any subjective reality, let alone an objective one.
But I was living above a couple where the woman always was seeing dead people sit in chairs if she entered the room, like, spirits with bodies but apparently not bound to stopping at doors or walls, so being able to be at the same place in the same time, as another thing. Apparently these ghosts or whatever they are, parallel beings, are all over the place, maybe there are a bunch of them sitting in your chair with you.

Now that you mention it.
(Its not like me to be so forward with paranormal stuff)

I honestly don't know what to think about spirits. If they exist, they would have to be a part of this universe because things outside this universe cannot be said to exist relative to us and if they could, they would just be a part of a larger universe than what we previously thought. What plagued Descartes was how the spirit controlled the material and the answer to that can only be that they are not separate things (unless absurdities are allowed in which case who can know anything). If something is not of this world, then how does it affect it? If something affects this world, then how is it not of it?

Perhaps what the woman is seeing is temporal overlays or temporal artifacts piled on top of each other like superimposed holograms. There isn't anything actually there, but her mind formulates it in that way as a mechanism of understand something she is perceiving. She could be personifying (reifying) some abstract perception.

Anyway, from the point of view of light there is no time or space and the emission and reception of a photon is the same instantaneous event. Actually, I think it was Max Planck who said that before a photon could be released, a particle would have to travel back in time from the destination and the arrival of said particle actually seemed to have inertia to move the emitting particle backwards as it released the photon (apparently this has been confirmed through observation). I'm not sure which direction "backwards" is since a photon is released in all directions. Perhaps backwards in time? Anyway, the point I'm making is that time and space are integral to each other.

Are you saying a photon has no direction?
I don't understand. Also not about the instantaneousness. Doesn't a foton take 8 minutes to travel from the Sun to our eyes and trees?

There is not supposed to be a direction. The problem is the division in physics between classical (waves) and quantum (particles). I prefer the classical waves as I believe that is a picture that is most real, but the quantum "quantizes" a bit of the wave into a particle like calculus quantizes infinitesimals and then adds them up. It's a mathematical crutch imo that happens to yield the right answer via the wrong picture by chopping things into pieces that are not actually made of pieces. Physics is a mess imo. It's not that terribly difficult to understand, but the difficultly lies in making sense of the various perspectives and vague and variable definitions. I mean, there are pages and pages on quora answering the simple question "what is heat?".

Yes, light takes 8 min to reach us from the sun from our point of view. But from the point of view of light itself, it was instant. That's Einstein's relativity. The light from the farthest galaxies took 13 billion years to reach us from our point of view, but was instant from the point of view of light. Light doesn't travel trough time, but only space and only relative to things travelling less than the speed of light through space.

If consciousness is the aperture through which the universe observes itself, then it seems likely that it could only occupy one spatial, temporal coordinate; otherwise there could be no feeling of self and other; I and everyone else. Then again, consciousness is not solely a function of s,t location or else our body would be irrelevant. So it appears therefore that continuity is what matters.

Yeah definitely. You have to be at least able to recognize a pattern from one moment to the next to recognize that you're recognizing anything so I guess to exist as a consciousness you have to be conscious of something which is steadily changing.

Maybe this is how Zen works. You stare into a wall where nothing is altered, and eventually you stop remembering yourself.

Zen is to live as how you beat your heart (unconsciously, mindlessly, purposelessly).

Reginald Blyth told Alan Watts that he had abandoned satori and had begun becoming attached to as many things as possible. Evidently living as a animatron is not all it's cracked up to be lol

Don Lincoln at FermiLab says we are always traveling at the speed of light (whatever that means) through spacetime (not just space), but light travels exclusively through space (not through time) while matter has a spatial and temporal vector that sums to the same speed of light. Also, an object completely at rest (relative to spacial fabric) would be traveling at the speed of light exclusively through time and not through space (the opposite of light). The point is that when the spatial and temporal vectors are summed, the speed is always the same. Discontinuities would seem to violate that.

Im a bit skeptic about this Don Lincoln.

Basically if you travel at the speed of light, everything that doesn't is completely flat, undifferentiated. That doesn't seem to be my world.

A lot of people like Don Lincoln because he explains physics so the average person can understand it.
