LIGO Detects Fierce Collision of Neutron Stars for the First Time

Dennis Overbye:

Such collisions are thought to have profoundly influenced the chemistry of the universe, creating many of the heavier elements in the universe, including almost all the precious metals like gold, silver, platinum and uranium. Which is to say that the atoms in your wedding band, in the pharaoh’s jewels and the bombs that destroyed Hiroshima and still threaten us all were formed in a cosmic gong show that reverberated across the heavens billions of years ago.

And:

Dr. Metzger estimated that an amount of gold equal to 40 to 100 times the mass of the Earth could have been produced over a few days and blown into space. For uranium the number is 10 to 30 times the mass of the Earth. In the coming eons, those metals could be incorporated into new stars and planets and in some far, far day become the material for an alien generation’s jewels or weapons

People use the term "mind-blowing" too often. This discovery is mind-blowing.
