http://www.astronomy.com/News-Observing/News/2010/12/New%20study%20shows%20earthly%20gold%20came%20from%20alien%20bombardment.aspx



The findings provide weighty new evidence that the gold, platinum, palladium, and other iron-loving elements found in the crusts and mantles of Earth, the Moon, and Mars arrived on mini-planet-sized impactors during the final phase of planet formation in our solar system.




Am I the only one who read this and thought 'hey... let's go mine the Moon and Mars for gold'?

This is true.

When site staff was young, they would sit around as the planet cooled, and watch the giant chunks of space metal agglomerate.

No shit. Elements as heavy up to carbon are made in stars. Heavier elements are made in supernovae, which happen to stars above the Chandreshekar (sp) limit, ~2.5 solar masses.

I'm sure there's plenty of gold, silver, copper, platinum and rare earths on all the rocky planets (Mercury, Venus, Moon, Mars).



But mining it and bringing it back to earth would be thousands of times more expensive than just mining it here.

There's more than enough of those metals on Earth already. The catch is most of it is under the ocean. We're going to be mining the seabed first before ever mining asteroids or the moon.

Currently, yes. Some day, if there is a very high demand here, and we run out, then it might be profitable.

getting it down a gravity well is simple , is getting the first mining equipment and factory out of the gravity well that is difficult...

I wouldn't say I'm particularly surprised.






I'm no geology expert, but I guess I assumed gold was similar to diamonds and other rock formations in that it was formed via pressure and time and all that fun stuff.







From what was it produced? Hell if I knew. But I guess since it is its own element (unlike diamonds... which are just carbon, no?) it had to have come from somewhere rather than being formed from some process.







I guess you can all ignore my ignorance of geology and stellar physics and move on.

You were given the answer just above:


Quoted:

Stars when big enough can fuse lighter elements into waste as heavy as iron, then they hit a brick wall, there's no way in the Universe to make a star big enough that can fuse iron, anything with enough gravitational pressure will just fall in on itself into a black hole, or be so hot it won't stay together.

When the star goes nova, in the instant of detonation, the remaining hydrogen, helium, oxygen, silicon, carbon, iron etc, gets smashed about at random, and in the enormous heat and pressure, the nuclei of all the other elements are made. A lot are impossible combinations, and very short-lived isotopes that break up almost immediately, and everything gets produced in the distribution we see in the periodic table of elements. Roughly speaking, the heavier it is, the less you find.

Wouldn't that mining activity damage the interstellar environment and cause galactic warming?
