I think the correct explanation has to do with relativistic mass. Accelerated gold ions will have an increased (relativistic) mass. Therefore, the gold coming out of the accelerator will have a higher value than the input. You just have to sell by mass. --[[Special:Contributions/172.68.78.22|172.68.78.22]] 16:14, 15 June 2018 (UTC) | I think the correct explanation has to do with relativistic mass.

Isn't a typical cash-for-gold store where you would take your gold and walk out with cash for your gold? It sounds like Randall's proposal is gold-for-cash stores instead.

- Yeah, we need to calculate the increase of mass at 99.99, 99,999, 99,9999 percent of the speed of light. I didn't check but I'm curious how many 9s we need to reach the mass of the Earth for a single gold nuclei. Nevertheless the speed is zero again when you collect them, or you have to move at the same speed, but than you can't measure that increase because you're in the same reference -- and back on Earth your own mass would have grown out far beyond the mass of our Milky Way. --Dgbrt (talk) 18:11, 15 June 2018 (UTC)

- It makes sense if his proposal is to sell the gold to the stores, where he would just need the stores to agree to buy the high speed particles. I thought he was suggesting consumers would buy the excess gold particles in the stores, but that's probably not what he meant. Ianrbibtitlht (talk) 19:14, 15 June 2018 (UTC)

My first thought here was that he was proposing a gold-ion particle beam weapon. 162.158.106.240 20:10, 15 June 2018 (UTC)
