The brain "technology" rests on atomic interactions. These are dominated by 
the electromagnetic force fiels with symetry U(1). There is a small part 
coming from electroweak force with symetry SU(2). Not looking at nuclear 
matter, we can summarize our world as U(1)xSU(2).

Now, think about a quark star with long range color force SU(3). That may be 
seen as a "space" with symetry: U(1)xSU(2)xSU(3). So this space contains a 
duplicate of our world. There could be "analog" atom with "analog" chemistry 
in that environment. Why not analog life? If our U(1)xSU(2) world was copied 
to U(1)xSU(2)xSU(3) would that matter? May be the last part of the movie 2001 
a Space Odysey was about something similar.

More general yet: What about U(1)xSU(2)x(anything)?
