Quantum Physics and the End of Reality by Sabine Hossenfelder and Carlo Rovelli

i am suprised by your reply. Very expressive, I'm sorry you feel so frustrated. i came here to expand on 'Thirdly,," I' don't know that particle pairs traveling in opposite directions in a vacuum is comparable to radio waves in air or electricity in a wire. Doing similar thing numerically takes away the physics. I'm not persuaded to give up on material reality There isn't just outputs of an equation or processing without any source of input, just randomness. There isn't just the chaotic 'data pool' prior to receipt. There isn't just material existence. All 3 play their part , allowing sensory perception of the world. Human's are embodied and think and feel.

Georgina,

You, like almost all of humanity, are trapped in a huge maze of our ancestors creation. A "reality" maze, with no entrance or exit. You, like everyone else, was born inside it. And it was built inside an even larger such maze, and that within another even larger...

You can either stumble around lost within it, for your entire life (like the physicsts have been doing for the past century), looking for a non-existent exit, or you can smash your way out. The choice is yours. You can either be like Alexander the Great and simply destroy this Gordian Maze, or you can remain forever, bound within it.

Shannon gifted us all with a weapon, powerful enough to smash the maze. Use it. Yes, it is an awful prospect to have to rebuild everything, from the shattered pieces. But there is no other way out. Like the "Quantum Reality" puzzle I posted above, individual pieces can not be moved into an alternative new configuration, one-at-a-time, that "fits inside the box". Evolutionary changes are not possible. Only a revolutionary, all encompassing change, will ever suffice, to free you from the maze and provide you with an opportunity to rebuild it correctly. That is just the Nature of Reality, like it or not. And very few indeed, like it.

I'm not persuaded to give up on material reality

You do not have to. You only have to give up on your unwarranted belief, that you have ever inherited a reasonable Picture of Reality. But like most people, that seems to you, to be an even worse alternative. Like most people, you fervently hope to save the Picture of Reality that you inherited, and have invested your whole life in trying to maintain - like an old British Lord, trying to keep his old, inherited, crumbling castle, from collapsing, rather than tearing it down and building a new one. You can save it. But only at the cost of being forever trapped within your old, worn down, woefully inadequate Picture of Reality. And never even catching a glimpse of Actual Reality. The choice Is yours. The irony in that, is that all the people like yourself, are running around with smart-phones etc, that would never work, except by exploiting Shannon's discovery. You all seem to believe that those communications signals, would appear like just a very fast sequence of ones and zeroes, maybe with a little bit of error correction thrown into the mix. They do not. Just as Shannon said they must, they would appear to you, as meaningless noise. In fact, in many cases, your concept of "measuring" them, would fail to even establish they they exist, all around you. Using your antiquated "Picture of Realty", you would never observe anything at all, other than noise. There is nothing there to ever even be "measured", via the hopelessly naive concept of "measurement" that you and physicists, are clinging to.

David Eagleman has shown perceived occurrence of events...

The problem is, if you can never even "perceive" that an "event" ever even occurred, that will never work. But that is exactly what many of Shannon inspired signals "look" like - events that have never occurred; just static noise that looks no different than if there actually were no events ever taking place.

As you can see I'd like to make quite a few modifications not just take what i have inherited as valid

I have indeed seen that, for a long time. The problem is, I have also seen that neither you, nor the physicists, in spite of your ardent desire, do not have the slightest clue of how to actually accomplish making any modifications that will get you out of the maze; because you all simply refuse to ever look at the incredible gift, that Shannon handed to you, because doing so, requires you to trash your entire inheritance, plus all the work you have put into it, to date.

That is why it has long been observed, as in Planck's principle, that revolutionary changes are usually only accepted, by people that have no such inheritance and have never wasted any of their own effort, trying to maintain them. No one ever succeeded in indoctrinating them (though many may have tried) into believing that their elders' ancient, sacred idols can never be desecrated and thrown in the trash - so they just go ahead and do exactly that. And they can succeed in doing so, precisely because there are no Laws of Nature prohibiting it - because there are no static Laws of Nature at all!

Reality is a process, still under construction; always was, always will be.

Sorry, I don't see how Shannon's work can be used

There is nothing to be sorry about. Ignorance is bliss. Just be happy that others that have seen how Shannon's work can be used, have provided you with your phone, TV, Internet, etc., that add to your bliss. Be happy that your paycheck never accidentally gets deposited in someone else's account - as the result of a bit-error in a transmitted account number - a bit-error that Shannon discovered a sure-fire means to prevent.

And as for living creatures - Mother Nature discovered Shannon's technique, eons before Shannon ever did - you see it in action with every DNA double-helix copying operation. Or do you believe that all the zillions of potential mutations (bit-errors) have be avoided, by magic? And how do you suppose the signals flowing through your brain, do not become hopelessly garbled, by all the zillions of copying errors that would occur, in the process of being sent from one neuron to another and another and...

Ever wonder why neuron signals look like random spikes - like noise? As Shannon proved, only noise-like signals can be copied, without frequent errors, in a high-noise environment, like a brain. Shannon's technique is what makes complex life possible. Now you know. It is what makes all of Reality possible (well, at least all the deterministic parts) Now you know. And when even Shannon's technique becomes insufficient to prevent frequent copying errors, determinism itself, repeatable cause-and-effect processes, existing as a physical phenomenon, beginf to self-destruct, resulting in "the biggest, baddest boogey-man of them all - "Quantum Weirdness!" Now you know.

Most people do find it "pleasing", which is why they like to believe in magic, fairies, heroes, gods and unwarranted speculation, that will save them from whatever they fear, and from ever having to think about, what is on the other side of their coin - their "Picture of Reality." Their belief is the illusion; they have simply accepted the illusion as their reality. Ignorance is Bliss.
