The Boltzmann brain paradox - Fabio Pacucci

The Boltzmann brain paradox - Fabio Pacucci

video description

Rating: 4.5; Vote: 2
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. Given: Sean Carroll has a good dismissal of Boltzmann brains. Basically, the paradox behind Boltzmann brains forming is valid if our understanding of entropy is completely correct. However, if the universe as you or I experience it is a figment of the imagination of a brain, our understanding of thermodynamics is imagined, and almost certainly completely wrong. Boltzmann brains only works as a paradox if the brain imagines laws of physics that correlate to the universe that created it, which would be even more unlikely than the brain forming to begin with.

the singularity is very ordered but there are trillions upon trillions upon trillions upon trillions upon trillions upon trillions upon trillion upon trillions of singularities that could be valid universe starters. any singularity the position of the particles doesn't matter other than about the same point.
to get a brain thinking at least 1 exact thought let alone something as complex and meta as philosophy, is far fewer permutations.

whats to question if the ansers are right there and we still dont see them. the anser was indeed time nothing that mathers lives for ever nothing that didnt mater wont see what maters being the brain wil only be the brain stil in a inf cosmos being what it is. evrything are attoms so who knows what can happen if somthing fluxuate. wel got a prity idee but that me, so ya just keep the anser simple for now time is all you need to know

Just because the universe may exist for an infinite amount of time doesn't mean that everything possible can happen. If I had a bottle of water for an infinite amount of time, that water isn't going to turn into wine. The universe is the same there are a set of rules it must follow (whether we understand them or not) and only a certain amount of of configurations of atomic molecules, even if we haven't discovered them all.

Just because a universe is infinite doesn't mean anything is possible. An infinite universe still has laws and those laws apply throughout. Pasta is a food made by people from plants, it doesn't occur in nature. The universe will form gases, rocks, and planets where plants and people can evolve over time to make pasta, but will never form pasta by itself no matter how old or infinite it becomes.

I love this stuff. Barring one of these incredibly unlikely events happening (has it? Do weird unlikely things happen every day? , it s a thought experiment. Seems like we don t live long enough to answer these kinds of q s. Even if the light hasn t gotten here from the outer edge of the known universe, we re talking tens of billions of years. (13 or 14 bil they say. How can we ever truly know?

Say that the universe is infinitely big, then as a whole, an ista brain and a singularity that s leads to the Big Bang has the same chances of happening, there is only difference in chance if the universe has a finite amount of matter and space. Why same chances? Because when you say something is unlikely, just make the universe bigger, it s infinte.

I there is a constant amount of matter and energy in a given space, infinite time must lead to a never ending cycle of repeating the exact same constellation of atoms.
that was what i concluded at the age of 16 when i seen a box with some marbles rolling around inside of it. but that was before i learned people started to split atoms

Actually there's something that preceded the universe, we call him God. The fact that we exist indicates that there is something which had always existed otherwise we would fall to the paradox of infinite regression, therefore the presence of this eternal entity is a necessity for our existence.
reply

Yeah i thought this all might be a dream too
I mean i can t really be this much of a disappointment to my parents and myself
I ll just put myself out of misery when my savings run out and wake up to my mom calling me to get breakfast before school

reply

Once I had an acid trip where I realized I was a conscience floating on the void, imagining all this life over and over again.
Interesting to see that a scientist formulated a theory that approximates that illusion.

reply

Order, homogeneity, breaks into parts becoming heterogeneous, the parts further break down until all parts are of a fundamental nature and therefore are all the same, so homogeneity is restored. The universe must oscillate.
reply

They are ready to accept everything except God. What an injustice. Do they not notice the whole ecosystem in the earth, millions of creatures?
Just wait, the day is not far away when science will acknowledge God.

reply

A kind of a video arousing near infinite sorta urge to think, reason and rethink. We need to keep suggesting ourselves such ideas, that s what makes us a great opportunity for ourselves and the cosmos
