An article in a recent issue of New Scientist caught my attention on two counts: firstly, in what it said about my old friend wavefunction collapse and the measurement problem; and secondly, in mentioning Boltzmann Brains. Both set off my “Yeah, but!” reaction.
I’ll touch (as briefly as possible) on the first point, but this little Bubble is mainly about the second one.
Boltzmann Brains bug me.
