Collision Puts Wrinkle In Space-Time

When two black holes converged into one about three billion years ago, their cosmic collision managed to wrinkle the fabric of space-time. In fact, the impact was so strong it produced gravitational waves that have managed to reach earth, where sensitive detecting instrument, LIGO, only recently picked them up.
These two black holes, one with a mass of 30 suns, the other a mass of 19 suns, danced around one another for ages before finally merging in a collision that rocked the cosmos. The result of their attraction? A cosmic conundrum made up of a single black hole, weighing an unfathomable 50-solar masses of endless space-time.
But, this discovery isn’t just cool, it’s actually changing what researchers thought they knew about black holes. Scientists are beginning to re-evaluate some of their theories about stellar mass black holes.
