Can it be that it is our conscious that "collapses" the wave function according to what it considers "logical" for a given event, whereas all the reality until confronted by our conscious is in an "undefined" state? That would explain why all measurements are so "consistent" with each other whether it be with or without an "eraser". Also, what does "until we look at it" mean? You don't mean human vision, right? Otherwise a blind person would never be able to experience the reality. So what is the "look at / observe" mean once we've agreed that the measuring devices are also in an undefined state until we "look at them"?

Let's say we have a Xenomorph on planet X. He shoots photons through double slit into space in our planet direction and collapses vawe functions by observing photon positions using some alien detectors. If we were scanning some distant planet X with a double slit setup on our end, and If we could separate such photons from other "noise" photons coming from that direction, according to this theory, we would get non-interference image at some point. Sounds like a good way to detect intelligent life instead of trying to find artificial radio signals throughout space if you ask me. ))

Naah, just kidding, I don't know what I am talking about. :)

When we speak of dimensions in physics it is important to recognise what is fundamental and what is constructed when it comes to dynamics. There can be no dynamics without time. If we consider the foundation of our physics it can lead us to a various cornucopia of spatial symmetries. But from the first not another thing can be, if we take our dimensional points seriously then we are forced to see time as fundamental and space as secondary. The point is the zeroth dimension, we all know it has no spacial extensions but it must persist. It must remain so as to repeat again and again flawlessly OR varied over a temporal duration. That dimension 1 is made of countless iterations (copies) of something with no spacial extensions is key. That for the point to exist at all there must be time before space. And only from a process of iterations do we achieve any formal dimensionality.

"My only regret will be that I could not say what I had to say in a way you could understand"
- James Torres -
A personal quote at the beginning of an essay I wrote titled, Q:
Now Q is the notion that there is not a 'reality'. And we can speak more of this later but Anyway, it is not a strait forward return in time but a convoluted one. Q is a dimension of multiplicity for each and everything in relation to ourselves as we rewrite history over and again.
To you,
Your lucid and detailed animation is exemplary; your analysis is top shelf, your explanations concise and replete with valuable information for someone like myself. I especially enjoyed the part where the two waves are excommunicated at the detectors and rejoined at will by the eraser device. It has always impressed me with the notion that we are dealing with a Manifold Time. None of the dynamics involved can proceed without a modified time but the temporal dynamics of consciousness provides us arguments for incorporating a superposition in time as a general extension of reality formation. All we have to do is give nature a second chance, literally to derive a concept of a statistical probability for each and everything respective of its Eternal recurrence in time. This could be useful to our understanding maybe? A modified (editors ) version of existence that recurs should be considered when anomalies in our current physics of time appear. For us to understand what the eraser is doing and what that implies we must abandon all hope of consensus reality. It is clear to me that when the detectors interact with the particles entering the device there is an entanglement that separated one particle reality from the other. The fact that both waveforms persist beyond the detectors but are no longer in communication suggests to me a separate reality or time with a little t for each. The eraser is a way of mixing or separating them from each others reality being in phase with the observers own reality formation. That is to say in breif that we are dealing with a statistical probability in a Manifold Time not a superposition in hyperspace. The universe is recurring and the particles wish to go where they have gone before and are subjected to those influences. The first law of motion is Inertia, that all things wish to continue doing what they have done before and that any change must require a force that takes the prior state of an object as its primary form. This is not our first 'time' around and there is a mnemonic property to what time is. Is there a temporal explanation that can resolve this? I think yes but it's very counterintuitive.

What if you trained a dog/chimp/dolphin/parrot to inform you of what was the recorded result vs one that wasn’t then erased the data would there be a difference on the background detector? Does it require human conciousness to determine the result?

Let’s say you have someone look at the data but then that someone is killed before they tell anyone then the info was either erased before the person was killed or after. What is the scenario for this? 
What if a dog gets to look at the pattern on the background detector before the info is erased from the recorder that recorded what slit it went through. So the dog sees either it went through the left or righr slit or a wave pattern form then you erase the info from the recorder that recorded what slit it went through and then a human looks at the background detector will it see a interference wave?

In order to distinguish the pattern on the screen (is it an interference pattern or a 2-lines pattern?), you need many photons. So in the present experiment you would repeat the experiment many times and memorize the results for each detector for each try. The problem I see here is that the choice is made randomly for each photon by a beam splitter. As a consequence, we cannot see the interference pattern before we get the information at the detector. But what if we instead send a burst of photons (just separated enough so that they can be separately detected by the detectors) and after all those photons have hit the screen, making a clear pattern, we choose what we do for ALL the heralded photons from the detector (we erase all which-way information for all photons or keep it all) ? In that case we should really see the interference/2lines pattern appearing on the screen before we decided what we are going to do with all the photons generating the pattern. Probably there is a problem but I can't figure out where it is.

Here's an experiment I'd like to see. A macro double slit with tennis balls and a screen where the tennis balls hit after being launched randomly in the general direction toward the 2 slits. Completely enclose the system so no one can ever see or determine which slit the tennis balls go through. It may sound stupid but it's been bugging me.

"We ourselves" aren't completely 100% photons. We "make a difference" because of the unconscious mind is separate and organic to photonic matter. Yet brain matter, it warps the unconscious mind [dark-energy] into revealing its non-objective observer state when it's being manipulated by conscious photonic matter.

If the beam splitter has >50% chance of being reflected/transmitted, would it destroy the striped pattern
