Boltzmann Brain Paradox
Comments center on the Boltzmann brain paradox, anthropic principle, fine-tuned universe, and probabilistic arguments questioning whether observers are likely evolved beings or random fluctuations in a multiverse.

we don't, check Boltzmann brain https://en.m.wikipedia.org/wiki/Boltzmann_brain
Similar arguments are made in scientific discourse.If you assume that the universe happened by chance, and the observable universe is just a part of a bigger multiverse, then you can ask yourself what is more likely:1. The whole, enormous universe happening out of nothing, including you2. Your small brain (no offense, we compare with the universe :P) happening out of nothing in a mental state that contains all memories of a world existing as you experience it nowOption 2. seems to be
Yes, people's imagination can run wild and hypothetical scenarios are limitlessIt is the same argument used to justify any opinion without proof[1] "Multiverse" vs. fine tuned universe: https://en.wikipedia.org/wiki/Fine-tuned_universe[2] "Choice" vs. responsibility: <a href="https://trendguardian.medium.com/free-will-a-rich-fairy
There is an Anthropic Principle solution. If the events occured differently, we wouldn't be here to observe them.
Can a Boltzmann brain exist in the absence of a universe?
You're referring to the Anthropic principle, which is a hypothesis, not a law of nature.It also says nothing on inevitability. These things could easily have just not occurred (knowing what we know) and then we wouldn't be here to observe them.The causal arrow is important.
Perhaps a Boltzmann-brain every now and then.
Well that rules out Boltmann brains https://en.wikipedia.org/wiki/Boltzmann_brain
His argument is sound. If there is infinite #s of universes, or the universe keeps reforming infinitely (implication being it will have varying degrees of uniformity), then it's mathematically probable that we would be boltzman brain's in a less coherent universe. We don't observe that.
Anthropic principle makes sense only for the past, not the future. We live in a universe with certain rules that make life possible, but there is no guarantee for the future. So why do the rules stay the same? The Bolzmann brain argument seems more probable.
