Pondercast Moon: The Secret Power of Words

"Now, let's get off, forget the camera." These seven words were the last ever spoken when humankind walked on the moon. Insignificant at the time, the Apollo 17 astronauts left those seven words floating into space in December 1972.

I wonder where those words are now almost 46 years later? If those sound waves had eyes I wonder what they'd have seen and experienced floating through space, watching the universe go by? I wonder what they would have felt so far away from home? And most importantly I wonder if those sound waves somehow might have changed the space around them just by being there?

Now if these ideas seem a bit abstract and difficult to imagine we need turn no further than Laurie Brown to help us ponder this cosmic ripple in space and time.
