Just read an article with a similar take on quantum physics. They created a quantum computer that could sort of rewind reality a couple seconds to recreate previous structures in atmos or electrons, like rewinding a game of pool to reform all the balls to where they were before the break

I alluded to that very experiment at the beginning of my overly long 'essay' and I did in fact link to it at the very end, tying up the conclusions, in my understanding.
Retro-causality is key. I did cover it quite a bit so won't go over it again, it's there if you want to take another peak. It was dense and it was ad-hoc, but I took several hours to get the fundamentals right.
The experiment that you have linked to here, which I linked to earlier, while actually being a 'similar take' as you put it, is in fact the polar opposite of the findings of the experiment that OP Valentine posted and that I 'backed up' with a recent similar experiment which came to the same conclusion.
It's an easy mistake to think they are saying the same thing. I did, in fact, at first glance, but they could not be more different in their outcome.
This Russian experiment breaks Time's Arrow. It says that the second law of thermodynamics is not sound and entropy as we know it is wrong. They may be right. I am not saying they are not.
But if they are right, then the experiment that Valentine posted and the one I posted must be wrong. You can't have it both ways.
This is what is so exciting about these recent developments. They seem to be really boiling stuff down to 'shit or get off the pot' physics. Enough fucking about. Either time can travel backwards (as in the Russian experiment you posted) or it can not (as in the experiments both I and Valentine posted).
And with the greater implication that there can or there can not be an objective reality as we humans would currently define it. The two conclusions are inextricably linked and mutually exclusive.
The implications of either outcome are astounding, none the less. And I don't think any one here is saying "I have found the TRUTH". But I took the time to write what I did because it so closely corresponded to a very similar but yet very disparate experiment that Valentine posted.
We are now reaching the point in technology where things are 'good enough' to finally get some answers. It's been an onward progression since the end of the last century, and it's getting better all the time.
The fact this Russian experiment shows contradicting results just makes it more fascinating.
I see quantum physics as yin and yang. Two halves that are polar opposites but yet with a small component of their exact opposite inextricably nested in their core being. That is why just when you think you have found 'it' - the whole thing collapses and you have to go back to square one to try to understand again.
This is why I wrote all that "GOTCHA" stuff as I was coming to terms with nonlocality and phenomenology - I was struggling because just as it all made sense, it then just made absolutely no sense at all. I was worried that I was giving out wrong information. I had to seriously pause for hours to get it right.
Welcome to the world of Quantum physics!
Valentine posted this video:
I'd come across that in my travels as well in the past year or two.
It's worth a watch, because it does explain a lot of stuff.
No one knows what is really going on. But it's fun to watch all these experts fight among themselves and start to begin to come to some conclusions at least.
This is a relatively new field, but a century old, but it has yielded real world results, not least the atomic bomb! Here we are almost a century later, still dancing around the garden, arguing the finer points.
Quantum physics is not just counter-intuitive. It is contradictory and paradoxical. And that's why dumb motherfuckers like me can at least have a go at understanding it. If you have consciousness (are alive) then you have a ready built in quantum computer which is your brain. It's the most efficient quantum computer known to man, in aggregate. It's pretty ropey and inefficient compared to a 'real' quantum computer, but it's the best we have. It would have great difficulty in working out the classical Traveling Salesman Problem, but then again, it's got things like 'consciousness' going for it. The ability to perceive light in all its waveforms and to process that information in a way that is not only meaningful, and which can lead to survival, but can also be 'beautiful' as well.
I'm getting mixed up here. Don't listen to me. Just musing.
You need a certain level of IQ to understand this stuff, but more than that, you need to put the hours in, as I already said, to really get to the bottom of it. Also to keep up with latest research, as both you, me, and Valentine have done, DC.
I just watched a lecture by John Carmack last night who was the main developer of Doom (the graphics engine). He touched upon Quantum stuff as well but explained it wasn't necessary. But it did touch on it. Interesting as from a viewpoint of how to recreate reality and create 'virtual reality' which he is at the forefront of now. That and making rocket ships.
It was interesting to hear him go in to detail about rendering, and the parallels it has with audio rendering, with both light and audio being propagated by waves. But still being treated as discrete particles (quanta) since that is more manageable for modern computers, until they get insanely faster and can do true unbiased rendering.
At that point, it may be very difficult to distinguish between true reality and virtual reality. For now, virtual reality is just poor reality. But we are edging ever closer.
The study of how light behaves (wave/particle duality) is of course at the very forefront of these experiments with regard to the OP. And of course, how we perceive them, in either subjective or objective reality.
My mind is open.
I have a feeling the Russian experiment will be found to have flaws in it. I might be wrong. But it reminds me of when they did that experiment where the speed of light was found to be faster. It caused a ruckus in the science field, but it turned out that poor callibration of equipment was to blame.
We can of course go faster than the speed of light, or rather, it is possible to exceed the speed of light, as per the ever exponential expansion of the known observable universe. These are not contradictions. But within the bubble of universe that we live in, light can not propagate at faster than 186,000 miles a second.

Back to reflection and refraction, two of the main techniques in 3D rendering. See John Carmack's lecture. I'll link it if you like.
Photons travel fast in a vacuum, and are totally stopped by solid materials, but in water, the speed of light slows down as well. Interestingly enough, you also have sub surface scattering where photons go under real world materials and kick back and emit back out at new random angles. See how your skin glows red in direct sunlight.
When things start going red, you know they are slowing down (photon wise) - the coldest stars burn red. The hottest? Blue.
See black body radiation. John Carmack touched on all of this in his lecture:
It's interesting to note that when computers do get fast enough, and especially then if we do get a true quantum computer, we can go back to techniques that were originally thought up in the 60's/70's that are far too expensive to work on today's computers: Radiosity, true Global Illumination, and the poor man's version of Ambient Occlusion. Sometimes 'good enough' is not 'good enough' and you have to take the expensive version to get a convincing render of what you want. Trial and error.
Once you can truly solve these problems you are in a new world of simulation. But still, will we ever solve the consciousness problem and get true AI?
It's frightening what we can do with Machine Learning. Truly frightening. But true Strong AI is centuries off I believe. But that is not far.
All we have to do is not bomb/stab the shit out of each other in the meantime. No easy feat I know.
It's also interesting how game development (and I know we have a few game developers here on RVF) takes a multi-disciplinary approach. It's not just game play, but AI, how characters react, psychology, how can we make this game more addictive, and also the actual boring graphics engine where nerds like us that do 3D shit will work out the best material to be intercepted by the renderer of choice to show all those reflections and refractions. John Carmack said that we don't need better renderers but better materials that more reflect reality as it is.
Chuck in a bit of marketing. And you got Doom 4!
We won't even go in to the recent debate about if the recent NZ shooting up of that mosque was VR or poor real time video (as you'd expect off a GoPro streaming to Facebook with real time compression).
This stuff is just food for thought. I'm a dumbass. If anyone who really knows what they are talking about cares to correct me, I'll receive it with good grace. I was a serious failure at school with regard to maths. But it's amazing what you can do if you don't admit defeat, push yourself to the absolute fucking limit, and just keep cracking away at the 'problem'.
Just in case anyone still is wondering what the 'problem' is:

This is the experiment that backs up OP Valentine's experiment.
Excuse me Valentine for going off piste. Hopefully it was interesting.
