In another late night grocery shopping outing, the usual 70’s / 80’s muzak played on the PA system.

As I wondered up and down the strategically organized aisles, designed to maximize my time and thus spending, the music dragged one part of my brain back in time. Briefly, I recollected the circumstances of first hearing those tunes, all those years ago.

Then it hit me. That’s exactly what they want! More than soothing nostalgia: it’s time travel. Combine this with quantum theory, find the music of the early universe, play it in the grocery store, then poof! We’re there with the protostars of the Bing Bang.
