Need explanation for Feynman's statement
Someone with great patience can help me explain the statement mentioned in Sean Carroll's talk with great details. I managed to follow its logic but got stuck halfway.
Feynman says, "From the hypothesis that the world is a fluctuation, all the predictions are that, if we look at a part of the world we've never seen before, we will find it mixed up, and not like the piece we've just looked at (high entropy). If our order were due to a fluctuation, we would not expect order anywhere but where we have just noticed it. We therefore conclude the universe is not a fluctuation."
The thing is that I think I completely understand everything in the talk but this very statement. I think Feynman didn't care about writing comprehensible sentences for dummies like me. Therefore, I do dare to rephrase his statement this way and want to ask you if I have done it right:
"If our order were due to a fluctuation, we would not expect order anywhere but where we have just noticed it. However, in fact, we do see parts of the world we've never seen before every new second along the arrow of time with entropy increasing definitively. We therefore conclude the universe is not a fluctuation."
