Pajamas Media has a roundup of links, which will doubtless grow as more information is known. (However, one of their links, supposedly to a Miami Herald story about the Castro death rumors, instead currently points to a Space.com article titled, “Huge Hole Found in the Universe.” Wait… so Fidel Castro got sucked into a black hole???)
P.S. Glenn Reynolds blames “star-devouring space monsters” for the mysterious hole in the universe. Star-devouring, and Castro-devouring!
