The Boltzmann brain paradox - Fabio Pacucci

--
How do you know you’re a person who has lived your life, rather than a just-formed brain full of artificial memories, momentarily hallucinating a reality that doesn’t actually exist? That may sound absurd, but it’s kept several generations of top cosmologists up at night. They call it: the Boltzmann brain paradox. Fabio Pacucci explores this mind-numbing thought experiment.

When I was younger I had a thought a bit like this. I didn’t know about entropy and the eventual heat death of the universe and thought that time was infinite. In that case, wouldn’t every single possible scenario that could ever be imagined and all variations of them inevitably come true by the nature of infinity? For example, in the far future there will be an identical video made on a planet identical to Earth and a commenter with an identical life to mine will have made this comment, except the comment would end in a period

Key word being "possible" scenario. By the boltzmann logic, there is a probability that the universe does not even exist. Which would mean even a boltzmann brain couldn't exist, which effectively proves the universe is finite.

[@Esock114]

With infinity everything happens. Literally everything because infinity is infinity. Think about a grain of sand in a sandcastle, then relative to the beach it’s one Then relative to the sand in the water a few miles into the ocean in that beach. Then imagine the sand in that entire coastline. Then imagine that sand grain relative to all the beaches and desserts in the world. Then imagine all the sand in the ocean. A planet made of sand. A sun made of sand grains, a galaxy, a universe. Now imagine 100 universes of sand. Now 1 Million, 1 billion, now 1 billion billions. Take that billions of billions and raise it to the 2nd power, the 3rd the 1 trillionth. Remember that singular grain of sand? Now imagine one electron in one atom in the sand grain. Picture that electron as the timespan of the earth’s entire history from Pangea and microorganism in the ocean to now, to the far future. A minuscule part of Earth’s timespan is human history. Compare that slice of the electron to the grain of sand to the beach and the infinite universes full of sand. Infinity is such a immense concept that of course anything could happen. Infinity means anything.

"real universe"

[@banger2998]

Well it’s billions of times MORE likely that we are living creatures on the billions to infinite many planets throughout the universes history than a random brain appearing if it makes you feel any better.

[@NeilMalthus]

'Much more likely' according to a very select group of people who might just be mistaken, missing something in their reasoning / calculations. It seems very very counter-intuitive to believe their assertions and as a zoology graduate, that will do for me. With the power of hindsight, could the universe make any more sense?

[@mikicerise6250]

That depends on your assumptions. It's more likely than a fully formed universe like this one assembling, but certainly not more likely than a super-dense hot spot assembling and then exploding and decaying into this universe through entropy, as our universe appears to have. That is *way* more likely than a random Boltzmann brain assembly. xD Anyway, the thing is a fun thought experiment that highlights the problems with infinity. Don't turn it into another religion, please.

The other immortals saw him in the pit, but didn't help him because they knew they'd help him eventually as well, after all they have an infinite amount of time.

These illustrations are so beautiful and thought provoking! Although, while it is interesting to contemplate the probability of our entire existence being the product of an artificial brain, I think it is more of a question of how we understand scale rather than whether our universe is real or not. Everything is relative. What is a short amount of time for us, is an entire eternity for other life forms. Similarly, humanity is but a spec of dust in the history of the Earth, and Earth is but a spec of dust in the history of other stars and galaxies. While I am no scientist, applying these rules, to me, implies that there is another level of scale beyond the observable universe. And another level beyond that. And beyond that. Which are all simply impossible for us to comprehend, in the same way that the universe that we've created here on Earth will never be perceived by a fish or a grasshopper. As an artist, I find that our conceptual understanding of the universe plays a huge role in the direction of our queries. And find that putting scale and relativity at the center of our quest could allow us to draw relationships spanning beyond the current limits of our human comprehension.

This makes total sense to me. Ever since I was a teenager, it's seemed as if life is an illusion; a dream within a dream. The reason there's no such thing as "matter" is because nothing exists. Everything is our own personal dream-illusion. Those are the nuts and Boltzmanns of it.

[@TheAlpineAddict]

Reality may be our own personal dream-illusion, but the Boltzmanss brain experiment is a brain of matter existing in what we would call the "real" universe.

The explanation of entropy using the analogy of scrambled eggs is misleading. Because bowling an egg is not a closed system. You bring energy to it. What entropy really means, (or at least in my understanding) is that, in a closed system, matter tends to rearrange it self towards the lowest potential energy point. It doesn't matter if the outcome is ordered or not, as long as it's the lowest potential energy point of the system. If you put water and oil in a closed system, they will eventually separate. Which is the opposite of the description. Going from chaos, to ordered state. In others systems it goes the opposite way, but order/disorder is an eye appreciation, not an energy state appreciation

[@limerence8365]

Boltzmann's theory implies that there is disorder, then order, then immediate disorder (if I understand the video correctly), so the issue I have is what forces drove the brain to exist in that instance to begin with? Boltzmann's brain may be more likely, but we have no idea of the laws of physics in that universe. While we don't entirely know how the brain and life came to be, we do have a good understanding of the usual idea of how a brain evolved. Life evolved from simple chemicals and from that the brain developed. Life, though in one generation couldn't stave off entropy, could keep going through reproduction, and so far it's worked for 3.7 billion years. Boltzmann's brain could be true but we don't have enough knowledge to confirm it, only statistical maths, while we have lot's of knowledge of the common understanding of the brain. I remember learning about entropy from a Brian Cox documentary. He was in a windy desert and said there was nothing stopping the wind from blowing sand into a sandcastle but it was more likely to be just dunes and hills, and the wind would soon erode the sandcastle, showing entropy at play. But as I watched I thought, the wind may not build a sandcastle, but Brian Cox did, and he's part of nature just like the wind. And if you look at the patterns that the wind makes in the desert, it's not chaotic, it's beautiful swirly sand dunes. Order comes from chaos all the time. So it got me thinking, what is 3.7 billion years in context of an infinite universe, nothing more than a blip? So maybe both Boltzmann's brain and our usual understanding of a brain are both true and the only thing stopping us from getting that is an undervaluing of the true complexity of the laws of the universe.

Entropy is not about order, its about the amount of information in a thermodynamic micro/macrostate

BTC's price has been fluctuating lately, which means the market is currently open and you cannot tell whether it is going to be bearish or bullish. This uncertainty is driving most traders away and forcing investors to hold. I would say it's totally wrong to just sit back and wait, maybe make a few losses, this is the wrong way of thinking for an investor because as an investor it should be our job to find ways to add and recharge more and more coins as the ultimate goal of making a profit. It all depends on the pattern you are trading in and the source of your strategies as well. I started at 3.2 BTC and accumulated over 17.5 BTC using the correct trading strategy given to me by an experienced trader, Theo Ryan. His methods are top notch and profitable.

I feel there should be a distinction around the possible existence of Boltzmann brains and claiming those consuming this content could be Boltzmann brains. The possibility is already wild enough, but the odds of a Boltzmann brain joining this server of existence while also being formed with enough legitimate understanding of the underlying universe to contemplate the fact that it might be one of these anomalies seems altogether different.

ngl the idea that everything I experience is simulated in a brain floating in an eternal void that spontaneously appeared and disappeared out of pure chance is pretty cool. it's like if the 'it was all a dream' or 'we're in a simulation' cliche was taken to it's logical extreme. hella bleak but oddly funny xD

Imagine two Boltzmann brains which are entangled with each other. A version of an Alice brain and a Bob brain, each of which believe they are conducting an entanglement experiment together. Of course it's possible for there to be an Alice brain and a Bob brain which aren't entangled, so, Alice's measurement might not affect Bob's state. But it's also possible for them to in fact be entangled and for the system of two Boltzmann brains to evolve according to Alice's perception of measuring the particle on her side of the entanglement. The Bob version of this Boltzmann brain system evolves accordingly. In other words, we have two Boltzmann brains sharing (one tiny element of) each other's conscious, perceived "reality". Wowza! What follows from this? If you accept that Boltzmann brains are possible (I'm not saying you have to, I'm just saying, do the thought experiment with me), then you have to accept that the preceding is possible. And if you accept that, then, of course the conclusion is the possibility of an entire planet's worth of Boltzmann brains, which all agree on common elements of their perceived reality. And no way to tell it apart from a "real" planet full of sentient beings.

[@mechaminer2361]

Hmm…. So basically a planet of beings that experience the same life? The same general life (like there are aspects of their lives that are different)? Please explain in more detail, it is not your comment, I just do not have the intellectual capability to understand your great thought at first glance!

[@glowingfatedie]

@@mechaminer2361 "So basically a planet of beings that experience the same life? The same general life (like there are aspects of their lives that are different)? " I mean, yeah! Exactly! One of the things I'm pointing out is that not only is there no way for any individual to tell they're not a Boltzmann brain, there's no way for a planet of sentient people to tell that they're not all a bunch of simulated beings, in a shared consciousness simulation together. Or that their entire planet isn't simulated. Or that their entire visible universe isn't simulated. You might want to see my other comment where I show why, even if all this is possible, plausible, likely, or even 100% true fact, it still doesn't (necessarily) mean that we ARE in a Boltzmann reality.

@@ximonwhhatt3796 I dunno my dude. I would guess hallucinogens would be more effective at that than just living and dying. Let me be more clear. I think we are all already connected to unlimited collective conciousness. As much as we allow in. Some can handle more than others. That's ok. Those who don't even try...well, they should be encouraged to. To borrow an analogy, we are antennas for the programming that the collective conciousness (which existed far before me, and will exist long after me as well) pushes through the airwaves. I am not sure I bring anything to the table. 🤣 For every question I ask, already has an answer. Every experience I have is merely a permutation of something done before. (Perhaps thousands of years before.) I don't necessarily think WE add to the collective conciousness as much as are programmed by it, and allowed to use it, if need be. As a whole, I believe, for the most part, things will slowly get better for humanity. But I am not sure we are ADDING to the collective conciousness so much as turning other people "on" to it. If that makes sense.
