    Golden showers

    All the world's gold and platinum ore came from outer space after a mammoth meteorite shower battered the Earth more than four billion years ago, scientists revealed today.

    Researchers also discovered there is enough gold and platinum in the Earth's core to plate the surface of the globe with a layer of priceless bling four metres thick.

    These huge gold deposits appeared during the Earth's formation when molten iron sank to its centre, dragging with it vast quantities of precious metals.

    Question - what would happen to price of gold on world markets if an all gold asteroid size of Moon shown below collides with this planet?

    Some diamonds to be found are older than the Earth, albeit very small.

      Sounds like rubbish to me. Why would gold and platinum not make up a non-golden-showered Earth?

      What's more likely is this: The primordial solar system dust cloud contained about 0.13 parts per billion gold and as it coalesced (lots and lots of not particularly golden meteor showers), the Sun ended up with about that ratio of gold. While the inner planets (including Earth) got proportionally a bit more because they were too hot and not massive enough to hold on to the commonest and lightest gases (hydrogen and helium), and the outer planets, which are more gaseous, were left with more than their share of lighter elements and less gold by proportion to the rest of the solar system. Not sure about asteroids, presumably they had trouble holding onto helium and hydrogen too.

        I have never been so disapointed with a thread.

          Though I spell "disapointed" like this - disappointed

            Austerity measures. We can't all take the p.

              Some scientists spout a load of nonsense - none of this stuff is provable and will probably be "proved" wrong in 10 years.

              Can't they work on something useful to industry?

                Gold and platinum are both important to industry.
                While you're waiting, read the free novel we sent you. It's a Spanish story about a guy named 'Manual.'

                  Every atom on the planet came from outer space Shirley?

                  Science isn't about why, it's about why not. You ask: why is so much of our science dangerous? I say: why not marry safe science if you love it so much. In fact, why not invent a special safety door that won't hit you in the butt on the way out, because you are fired. - Cave Johnson

                    But where gold/platinum comes from does not matter.

                    Now if they found a way to mine more minerals then great. Or create more then great. But to speculate it comes from outer space....
