Study: Dead stars colliding forged gold on Earth
LOS ANGELES (AP) — A strange glow in space has provided fresh evidence that all the gold on Earth was forged from ancient collisions of dead stars, researchers reported Wednesday.
Astronomers have long known that fusion reactions in the cores of stars create lighter elements such as carbon and oxygen, but such reactions can't produce heavier elements like gold.
Instead, it was long thought that gold was created in a type of stellar explosion known as a supernova. But that doesn't fully explain the amount of the precious metal in the solar system.
About a decade ago, a team from Europe using supercomputers suggested that gold, platinum and other heavy metals could be formed when two exotic stars — neutron stars — crash and merge. Neutron stars are essentially stellar relics — collapsed cores of massive stars.
Now telescopes have detected such an explosion, and the observation bolsters the notion that gold in our jewelry was made in such rare and violent collisions long before the birth of the solar system about 4½ billion years ago.

That keeps me reading for hours longer than I have time for.
It starts with one link, then another, then another... hours later I have read about the taliban in pakistsan, negative vacuums, and stars colliding to make gold. I have things I need to do.
There is just too much to read.
I just read the letter that the taliban leader sent to Malala and noticed that he is in fear of the new world order just like our militia guys. Now, I've got cued up topics on Peru, Limpbaugh, and Liz Cheney...
I think I may need to disconnect my internet because at times it seems like I am trying to read it all. And, almost no one I know reads as much about so many varied topics. Sometimes when I share what I've read, people look at me and ask me out loud: "how do you know so much?"
