Quality of the smaller black hole mass of our Sun is about 2,000 times, while the larger black hole mass .10 billion times the sun. .The study, published in "Nature" magazine. .</ P> <P> Boluo Sen said: "We found that the black hole at the galaxy size and the size of its very close relationship. This may be a small galaxy swallowed large galaxies the situation." He said, the two black holes .each orbit takes about 100 years, the distance between them is about 1 light year three tenths. .</ P> </ p>.
