A little while back I asked a question about quantum fluctuations, and I got some great answers.
Just recently, I stumbled upon a paper by Sean Carroll, which states that there isn't quantum fluctuations after all, in a De Sitter space in a vacuum state. He used this to argue against Boltzmann brains existing in the future when the universe reaches this De Sitter space stage.
I'm curious, is what Carroll is saying true? It makes sense, but it goes against what physicists have been saying for a long time.
Here's the paper: https://arxiv.org/abs/1405.0298
