This film: http://www.imax.com/hubble/

Gives you a marvelous 3D journey inside the pillars of creation. The humbling thing is that as you swoop around all groovy-like the back of your head says "in order for me to experience any change in perspective at all I would have to be travelling many times the speed of light, in which case I couldn't see this, therefore my perspective is literally impossible."

...which is why I'm afraid I have to share with you that you did your job wrong.

The far pillar is 4 light years. 1 AU is the distance from the earth to the sun - or 8.3 light minutes.

4 light years is about 253,000 light minutes, or AU.

In other words, you're off by three orders of magnitude.

Humbled yet?

Lemme put it another way. At the bottom end of your line would be earth. Somewhere near that top white star, the 2nd one, would be Alpha Centauri A and B.

I agree with your calculation.

To put it simpler for the non math sorts: each tiny box = 1000AU

You're both right. Dammit, math strikes again. Okay, so let me try to make this right. Here we go.

Each box is 1000 AU, so inside each box we would have, roughly, the same distance as:

  500,000 trips to the moon
  34 trips from Earth to Neptune
  8 Voyager 1 missions as of February 2012.
Plus, Carl Sagan explaining what would happen if we travelled at the speed of light. http://youtu.be/lPoGVP-wZv8

Or, 10,000,000,000,000 trips to the kitchen to get another snack while you're watching Sagan on TV.

(Assuming 25ft from the couch to the fridge => ~100 round trips/mi and 100,000,000 mi/AU, roughly speaking, of course).

Assuming each trip takes one minute (I suggest crackers since the'yre faster to grab), it would take 525,600,000,000,000 years for us to cross the distance. Which, considering the age of the universe as 13,000,000,000 years, would take around 40,400 universes at that speed.

Now that's a lotta crackers.

But still, math aside, its a bad ass scaling. Nice work.
