Echoes

Kathryn Cramer posts about her father, a physicist at the University of Washington, creating a simulation of what the Big Bang sounded like. I gather it's been Slashdotted and everyone's talking about it and everything. Cool stuff. But what I haven't seen mentioned is that you can also hear what the remains of the Big Bang sound like. Robert Wilson discovered the background radiation left over from the Big Bang in 1963 along with Arno Penzias, both of Bell Labs. There's an audio recording on the Bell Labs web site of a lecture Wilson gave some years ago that includes the actual sound of the background radiation left over from the Big Bang all these years later.

What do you mean there is no cat?

"You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat."

- Albert Einstein, explaining radio
