Gold synthesis in an accelerator
Gold synthesis in a particle accelerator is possible in many ways. The Spallation Neutron Source has a liquid mercury target that will be transmuted into gold, platinum, and iridium, which are lower in atomic number.[citation needed]
Gold synthesis in a nuclear reactor
Gold was synthesized from mercury by neutron bombardment in 1941, but the isotopes of gold produced were all radioactive.[3] In 1924, a Japanese physicist, Hantaro Nagaoka, accomplished the same feat.[4]
Gold can currently be manufactured in a nuclear reactor by irradiation either of platinum or mercury.
Only the mercury isotope 196Hg, which occurs with a frequency of 0.15% in natural mercury, can be converted to gold by neutron capture, and following electron capture-decay into 197Au with slow neutrons. Other mercury isotopes are converted when irradiated with slow neutrons into one another, or formed mercury isotopes which beta decay into thallium.
Using fast neutrons, the mercury isotope 198Hg, which composes 9.97% of natural mercury, can be converted by splitting off a neutron and becoming 197Hg, which then disintegrates to stable gold. This reaction, however, possesses a smaller activation cross-section and is feasible only with un-moderated reactors.
It is also possible to eject several neutr

You assume gold is plentiful throughout the galaxym and they would never travel that far to get it.

You are obviously a skeptic, but I see you make the same presumptions, which you have no understanding of, as do proponents of the UFO visitation school of thought.

1. How do you know Gold is plentiful?
2. How do you know where they are coming from?
3. Do you under and anything about their propulsion mechanisms? If not, how can you assume how much it costs? If they are getting here via an established portal, maybe there is literally no cost.

I read an article somewhere that a high ranking English government official was worried about aliens coming here to take our gold. He stated that we should protect our gold. I guess not everyone in Parliament is normal
I don't worry about aliens coming and taking my gold. They can take it, maybe I can bargain a trade for a good recipe or something.....Shows you guys how little gold I have. I like the color of copper better than gold myself.

According to John E. Ross and Lawrence H. Aller (1971) of the University of California, the solar abundance of gold can be expressed as
log [ N(Au) / N(H) ] + 12 = 0.7
Which means that there is one atom of gold for each 200 billion atoms of hydrogen, in the sun.

Considering that we now manufacture diamonds, it cant be that long until they produce gold in a Lab. I can understand them needing water and such things but NOT the gold, that is now a man made greed
