Mind boggling...

You would think as a geologist, I'd have a pretty decent grasp of big numbers.  4.6 billion years?  Sure, that's a LOOOOOOOOOOOOOOONG time.  I get it.  

I thought I was ok with 'trillion' too until I just read this:

Courtesy the credit crisis and big bailout packages, the figure “trillion” has suddenly become part of our everyday conversations. One trillion dollars, or 1 followed by 12 zeros, is lots of money but have you ever tried visualizing how big that number actually is?

For people who can visualize one million dollars, the comparison made on CNN should give you an idea about a trillion - “if you start spending a million dollars every single day since Jesus was born, you still wouldn’t have spend a trillion dollars”.

Amit goes on, so please hop over there and read the rest.  Stretch your brain a bit.

From the CNN clip, a trillion $1 bills stacked up would reach a third of the way to the moon.

Wow.
