    Well, n_FA. It's nice to know that if the collision of neutron stars is such a rare event and too rare to account for the amount of the heaviest elements that exist today, that there is another explanation for all the gold I don't have.

    Well it's nice to know that the reason you don't have it is more complex than that it's been stolen from you.

    Was his name Fafner?

    I got curious and it turns out that ancient Egyptian gold accounts for 0.1% of the world's total supply.

    World's total is ~ 187,000 metric tons https://www.usgs.gov/faqs/how-much-g...ience_products

    Ancient Egypt mined 6.7 million ounces https://en.wikipedia.org/wiki/Mining_industry_of_Egypt

    which converts to 190 metric tons.

    At least you were robbed by a colorful dragon. I was robbed by blood sucking leeches.

    That's pretty good of those Egyptians. They did it all by hand, I assume.
