Depending on which reference you trust, "trillions of galaxies" is
-one- of the numbers I'd seen bandied about.  I think a few hundred
billion is the more common estimate, though.  And too it depends on
whether you're using a U.S. "billion" or a Euro "billion" - they're
two completely different quantities.

according to:

There are more than one hundred billion (10^11) galaxies in the
universe
