[DUG] General Theory

[Alister Christie]

There are about 10^80 protons & neutrons (baryons) if this helps - which 
equates to about 10% of the mass of the universe (more than 99% of the 
mass of the visible component of the universe that is).  I would assume 
there would be about the same number of electrons.  But I'm a bit behind 
on my astrophysics, I use to read a lot of popular science books, but 
this new stuff about dark energy and the universe accelerating faster 
and faster as time goes on sounds a bit weird to me.

My guess would be that there are about the same number of protons as 
electrons - charge is something that seems to be preserved (Technically 
it's Charge, Parity and Time). There are, however other particles that 
are charged.  So assuming that the universe does not have an overall 
charge, there should be approximately the same number of protons as 
electrons - the exception being some of these other less commonly known 
particles making up the difference.

Are there any particle physicists that can clear this up (and probably 
set me wrong)?
