Boltzmann Brain Paradox Explained in Simple Words

A Boltzmann brain is not real, but what’s fascinating about it is that it thinks it’s real, and all the memories and experiences it has are real. But, of course, this brain is not real. But how would such a brain know that its memories are artificial and its existence is more like a hallucination? How would we know that we aren’t those artificial brains? This is the Boltzmann Brain paradox, the result of Ludwig Boltzmann’s many years of debate with other scientists on his interpretation of entropy.

In this video, we discuss the Boltzmann brain in simple terms and understand why we humans are real and not Boltzmann brains!

I remember renting the movie Dark City on VHS when it came out at the video store. After seeing how the advanced beings would freeze time and go around switching out the memories of humans and putting them in different positions to study humanity, I started to fantasize about this sort of idea. Blade Runner also touches on this topic with how they enter false memories into the replicants to make them believe they had childhoods.

There is a phenomenon that has nothing to do with this subject, but it popped up in my head.
When you want to create a random pattern, for example with tiles on you floor, you must carefully create it yourself. Because when you create them at random, they have the tendency to create something that seems a pattern.
I presume it has something to do with pareidolia

That’s a really difficult concept. Maybe it’s constantly happening in the universe and we would come back into a minute particle only to bang out big again! Spider-Man: I’m tired, I’ll fly away now! Humans: I’m tired, let’s go to bed! Love the animations! Keep it up!

Next time I have a discussion with my wife, I just have to think that I may only be just a Boltz brain.

[SuperBeanson]

I don't know if those 'scientists' who calculated the chance of a 'Boltzman Brain' is 'infinitely higer' than that of a human brain have ever heard of a crazy theory called 'evolution'...
You might say that the chance of the first replicator was very low, but can it possibly be lower than a thinking mind complete with a raft of coherent memories.
It would be a brave 'scientist' who asserts this, methinks

[JamesR]

I mean the argument falls apart when you remember that for the electrochemical functions of memories and thoughts to work, that brain still needs the power of a cardiovascular system, a respiratory system, insulation in the form of skin, and chemicals in the form of breathable air to stay alive long enough for those thoughts and memories to come into existence at all.

Be happy guys. Dont let people depress you. They don't matter. Hope you have a good day😊

[TheOrthoSaxon]

How would they be full of memories and why would they develop these. Plus how would these interact or is it just one brain

[onddu]

But one problem that i don't understand is that if our brain is just something that appeared with "false" memories, how come that these memories are correct enough that we could understand physics and quantum mechanics of the real (what even is real at this point?) universe and come to the conclusion that this is possible? If the thoughts are random and fake, as one would think, how can we still study the physics of the real universe? This just gets my head too tangled.

It reminds me of Bostrom's Simulation Argument. If humans one day advance enough to make simulations of our world (and we likely will), we are statistically more likely to be in one of those simulations than to be in the base "real world."

It also reminds me of Descartes, "I think therefore I am" argument. Descartes discounted the idea that we are being tricked into believing we exist by an evil genius.

[Anonymous-tmjp]

But then it seems we all have boltzmann brains, some particles randomly formed atoms, molecules, proteins, dna, cells, multicellular beings. Thus our brains are ultimately formed randomly only, where all the required particles were at the right place at the right moment

So we gonna just ignore 5:01 and not question why that part was added? ☠️

[ElectronicsGuitar]

Is there a difference in probability if the infinity is countable versus uncountable?

[llgante]

Wait, wait, wait, this sounds a lot like Descartes. Do these scientists give any credit to the philosopher?

[kaleijuka]

Whats the probability of a brain judt developing? Like clean slate.

Great video, thank you very much, note to self(nts) watched ……

"These models should be thrown out"
I mean it's infinity. With infinity everything possible is a guarantee and will happen. It's the nature of infinity. Anybody who doesn't agree doesn't understand infinity. And this doesn't only apply to infinite multiverses like on TV. It also applies to infinite time. And yes folks, also infinite space. If the universe is infinite space, there are an infinite identical replicas of you reading this same comment right now. Also in the future are there more infinite yous and everyone else, reading this comment, and every other possible comment, and doing everything else once can do, infinity, every second infinity across space, and in the future across time. Plus and infinite number of slightly different yous with just one hair out of place in time and space.. Also an infinite number of yous with a different shirt reading infinite comments and everything else infinite number in space and in the future. Also an infinite number of you with your thumb in your butt, reading this... No joke, everything possible not only can, but is guaranteed to happen infinity. On the bright side, that girl you liked, or that person who died, in an infinite universe there is an infinite number of mostly identical earths somewhere out there where she isn't dead and you two got together and lived happily ever after and are immortal, young, and happy, infinitely..

"We know that the model of an infinitely long-existing universe is a bust". No, we don't know that!

[radinelaj-cs]

What do you mean with : artificial memories ?

[MagicalToothpaste]

I don't know, I think I'd b e a boltzmann brain for sure - but what about consciousness itself?
