DR. OMED'S LABYRINTH ALBUM Snow was falling when I went out to walk my homemade labyrinth this morning. I wound my way to the center. Breathed deep. Turned about and walked out over my incoming footprints. Stood on the threshold stone and took a deep breath. Stepped off into the new day. Thoreau once said that he had travelled much—in Concord. I hope to travel much—in the seven courses of the labyrinth in my backyard. 11:37:00 PM    comment []

Astronomers in England have discovered a singing black hole in a distant cluster of galaxies. The black hole is situated in the center of a galaxy amid a group of thousands of galaxies collectively called the Perseus Cluster and located 250 million light years from Earth (meaning it took the light from these galaxies 250 million years to reach us). The sound waves coming from it are in the form of a single note, so rather than a song it is really a drone. Using the piano keyboard's middle C note as a reference point for the middle of the piano key music range the note is a B -flat. On a piano, the B-flat nearest middle C is located midway between 1/8th and 2/8th of an octave away. In musical terminology, this B flat is 1-1/2 steps from middle C.   The Perseus cluster black hole's B-flat, by contrast, is 57 octaves below middle C or one million, billion times lower than the lowest sound audible to the human ear! In terms of frequency (the time it takes a single sound wave to pass by), the lowest sounds a person can hear is 1/20th of a second. The Perseus black hole's sound waves have a frequency of 10 million years. Via NASA We thank Dancing Elder Sister Amanda for this link. 6:10:37 PM    comment []

Well, damn it all, I'm finally ready to post to the Tent Show, and the accursed blogware won't upstream the images. 4:54:43 PM    comment []
