From the New York Times on the declining birthrate of stars:
An earlier version of this article misstated the sound made by a black hole in the galaxy NGC 1275. It is that of a B flat 57 octaves below middle C, not 27.

That works out to a period of 10 million years, by my calculation. It must have been playing that note for a while now.
Hope there’s at least some vibrato or something to make the concert more interesting to those of us with short attention spans.LikeLike
