I've heard estimates of 100,000, but are they really accurate, or just a 
rounding down to the nearest hundred thousand?  Light speed, I've learned, is 
more like 186,282 mps, not 186,000.  One estimate I've heard about the size of 
the Milky Way is about 130,000 light years in diameter.  How close is that to 
the truth?
