## Main Question or Discussion Point

‘Everything can happen, will happen’ so the saying goes. So given infinite time a universe is meant to generate infinite Boltzmann brains. But I was thinking about this:

- Things that are possible can become impossible (example: heat death making Boltzmann brains formation impossible)

- Things that are impossible can’t become possible again

- So the probability space shrinks with time

- The probability space shrinking to exclude Boltzmann brain formation will probably happen before any brains are formed?

- After a certain period of time elapsed, Boltzmann brain formation becomes impossible?

- Argument assumes a universe with infinite time and space but finite mass.

Does this make any sense to anyone?
