WASHINGTON (AP) -- Everybody knows a trillion is a big number. But how big?
It's a one, followed by 12 zeros. Counting to a trillion, at one second per number, would take 31,688 years.
But that's still short of this year's projected federal deficit of $1.35 trillion.
That amount could pay for 40,000 baseball players like Alex Rodriguez, who makes $33 million a year.
You'd have to stack more than 2.4 billion Washington Monuments to reach 1.35 trillion feet.
Traveling 1.35 trillion miles would mean circling the globe 54 million times.
And 1.35 trillion seconds would take us back in time more than 40,000 years, to when Neanderthals were using stones to make tools.
