Recently, new results were released from NASA's Wilkinson Microwave 
Anisotropy Probe (WMAP) satellite, launched in 2001 to measure the 
temperature of radiant heat left over from the Big Bang, which is the 
theoretical beginning to the universe.  The new WMAP observations, 
announced at a NASA press conference today, reveal what the universe was 
like in the first trillionth of a second after the Big Bang. From the 
microwave background, researchers teased out a new signal called the 
"polarization signal."  According to the conclusions of this report, during 
this growth spurt, a tiny region, likely no larger than a marble, grew in a 
trillionth of a second to become larger than the visible universe.  Well, 
I'm confused.  According to Einstein nothing can travel faster than the 
speed of light.  If that is true, how is it that the universe expanded from 
the size of a marble to something large than the visible universe in a 
trillionth of a second?  I'm neither an astrophysicist nor a physicist, 
which is why I'm asking this question here.  And please be kind, as my 
calculus is a little rusty these days.  Any thoughts?
