SoylentNews is people

Scientists are using computer models to answer what many believe is one of science's most puzzling questions: How did heavy metals like gold get to Earth?

There are two candidates, neither of which are located on Earth—a supernova, a massive star that, in its old age, collapsed and then catastrophically exploded under its own weight—or a neutron-star merger, in which two of these small yet incredibly massive stars come together and spew out huge amounts of stellar debris.

In a recently published paper in the journal Physical Review Letters , researchers detail how they are getting close to an answer.

"At this time, no one knows the answer," says Witold Nazarewicz, professor of physics at the Facility for Rare Isotope Beams at Michigan State University. "But this work will help guide future experiments and theoretical developments."

From the paper, "Impact of Nuclear Mass Uncertainties on the r Process."

    Scrolling banner, check.

      Someone said that SoylentNews has been redesigned. In my browser it looks the same except that the link from the upper left corner to the main page, has disappeared. Is there any chance that it can be re-added? I found it more convenient than the link in the middle left under "Sections" and more convenient than editing the URL in the address bar.

        I don't know if this helps your search for the missing link, or not:
        In my browser, the link in question is now animated- zooming across the top of the page from right to left.

          I tried viewing the site in a different browser and it works just as you describe. So that's all right then.

      I'm going to get eye-cancer from all this blinking and shit. This is anything should show that nostalgia for ye' olden days is just bullshit. What a long way design wise we have come in a couple of decades.

      Did you check the source (or viewed the site with an old browser) that there's really no blink tag? Because modern browsers don't honour it.

      Aliens are very rarely sated, but if you feed them enough humans . . . Do you know that there are dead brown dwarf stars that are composed entirely of crystalized carbon, but we earthlings might call, diamond? Just think if we could get close enough to a supernova to collect the astrophysical quantities of gold pouring out of it at super mega kelvins! Too hot to touch! To hot to look at! Too hot to, . . . where did all the humans go? Stardust to stardust, ashes to ashes. Could I interest you in a piece of selling Faceboot to a Billion Indians? Numbers almost as good, logistics slightly more probable.

    Satan put the gold in the ground while he was burring dinosaur bones to test our faith.

      He tests faith because that sort of believer's reading comprehension suits him just fine. Assuming, of course, they've ever actually read the relevant bit [biblehub.com]...

    It was produced by early alchemists. The reason why later alchemists were unable to repeat it was that the early alchemists had used up all the philosopher's stone.
