If Boltzmann had a brain like Trump,
It'd bluster, it'd brag, it'd thump -
"All entropy’s fake,
A Dem hoax, a mistake!"
Then collapse in a hot, noisy lump.

More people writing/talking about organic molecules in space as if it’s a new idea.
But I wonder ... if a given volume of spacetime has a simple organic molecule in it — glycine, say, as compared to just an atom of hydrogen — does that increase the probability of the occurrence of a #BoltzmannBrain round it and perhaps increase its durability? Long enough to write a microblog post perhaps? 🤔
Maybe that just happened?
Has anyone tried to quantify this?
Yes, The #BoltzmannBrain hypothesis is refuted by evidence. Just look out of a window and you see the entire world NOT collapsing into nothing in a nanosecond. But it is a useful probe regarding probability and how we should think about it, especially in the context of #Cosmology.

I was just re-reading "Why Boltzmann Brains Are Bad", by Sean Carroll [1]. There Carroll notes (on page 13) that
"There is a possibility of confusion here, due to the sloppy way in which physicists use the word “quantum fluctuation.” It’s helpful to distinguish between three different notions [44]."
Indeed. 🙂 #physics #boltzmannbrain
