Journey to the edge of space and time

Just the other day I was wishing for something like this as I mentioned Powers of Ten. This is a fascinating video.

One little tidbit I thought of particular interest was the little 70-light year diameter sphere that shows the extent of man's radio transmissions. Even if anyone out there is listening, our "hello" has barely left the transmitter...

The universe is so honking big...

I'm impressed they've gotten that far already. I also think it astronomically unlikely that anyone will be able to respond to us before we've moved on.
