'Birth cry' ('Big Bang') of the cosmos heard
Astronomers have recaptured the sounds of the early Universe showing it was born not with a bang but a quiet whisper that became a dull roar.
Mark Whittle of the University of Virginia has analysed the so-called background radiation that was born 400,000 years after the Big Bang.

Ripples in the radiation are like sound waves bouncing through the cosmos. Over the first million years the music of the cosmos changed from a bright major chord to a sombre minor one.

...
During the expansion there is a change in the frequencies of the sound waves that results in the characteristic sound of the Universe changing from a major third chord to a minor third.

"Listening to it I have to say that the Universe is a lousy musical instrument," says Professor Whittle.

1. A reverse
Picardy third? Never mind, just being a geek. Anyone know if there is a name for said reverse?
