Here are some thoughts and random numbers I will throw around.  Hopefully this will give you some perspective on your reality.  I recently read that it is estimated that there are 200 billion stars in the Milky Way galaxy (that’s 200,000,000,000).  Each cell in the human body contains 20 trillion (20,000,000,000,000) atoms.  Moreover, you are composed of about 100 trillion cells.  So if you do the math, which you might be a little intimidated by, you end up with 2 x 10²⁷ atoms that compose your body (That’s 2 followed by 27 zeros).

It’s a big universe!

Impressive numbers, no?  What if you could travel 2 x 10²⁷ miles in space?  Where would that get you?  Well, 1 light-year is 5.9 × 10¹² miles, and a reasonable estimate is that our universe is probably bigger than 40 billion light-years..  This means that the edge of the universe is 7.7 x 10²⁵ miles away.  If you wanted to travel as many miles as there are atoms in your body, you just might reach the edge of the universe…maybe further, if there is anything beyond it.

Of course if you could travel at the speed of light (which you couldn’t) it would take you 40 billion years, so you’d probably run out of time.  By comparison, if 40 billion years were considered one year, your life span of 70 years would be 0.05 seconds of that year.

So just how small are atoms?  Click on the atom below to find out:

I hope this gives you some perspective!

Oh, and somebody check my math…thanks.
