'Chris' said nothing.
A post under chrismb identified that the 'increase in the acceleration of space' was a decrease in entropy. This is not 'the expansion of space', this is 'the acceleration of the expansion of space'.
This is very important to get right in the discussion on the thermodynamic viability of the proposed statements that GIT has put forward describing proposed 'ME thrust'.
A gas experiencing an expansion into free space is an increase in entropy - it is approaching a lower energy state.
A space which is being caused to expand is being taken
away from a lower energy state.
The complexity that arises is that where there is simultaneously an expansion of matter into an expansion of space, the rate of change of entropy is not well-defined from what is known, because the universe may be heading towards a full 'blow-out' or a complete collapse and that't not really well proven either way.
However, if the space
continues to accelerate its expansion, then that will, at some point at least, inevitably be a decrease of entropy as it is a system that is
increasingly tending away from a low energy state.
This can be made clearer by considering matter that is not expanding but is caught up in this expansion - as the expansion accelerates the relative momentum of this matter moving away from each other is increasing, and an increase in momentum is a decrease in entropy. A momentum gain in the universe cannot be 'fuelled', by whatever means may be speculated, by an [also] increase in relative momentum between objects accelerating away from each other. If momentum is gained by the speculated 'ME thruster' means, then the acceleration between objects in the universe, viz. their relative momentum, must decrease not increase.
