Whirling Black Holes’ Dance to End in Cosmic Blast
Some 3.5 billion light years from Earth, in the Virgo Constellation, there are two black holes (binary black hole), locked by gravity, that are madly orbiting each other. But their orbits are continuing to close in and scientists from Columbia University expect that in about 100,000 years they will join together in one huge cosmic […]
Rhythmic Light Pulses Help Astronomers Accurately Measure Medium Sized Black Hole
Astronomers have calculated that there may be about 100 million black holes in the galaxy. And they mostly fall into two sizes… stellar and supermassive. The size difference has to do with how much mass they contain versus that of our own sun or solar mass. For some time now, astronomers have also theorized that […]
