However,

 Indeed.  I fight entropy every chance I get.  Unfortunately, there
always
seems to be more of it when I'm done.
 Which brings up the Ekpyrotic universe theory.  When branes bash
together,
where does the creation energy come from?  I suspect the energy
difference
between the branes would decrease, reducing the probability of another
bash.
So how many can be sustained?  Or are there an infinite number of branes
so
it will take an infinite amount of time to equilibrate?

Oh, invisible red dwarves can easily trensfer
the energy between the branes, it's judt
that they're asleep mow.
