:::Sorry, you know what ''invariant'' means in physics? And you can't sum p and m (simply squared both) by using the Einstein conventions c=1, it's in fact E<sup>2</sup>=m<sup>4</sup>+p<sup>2</sup> -- I fear most people still don't understand. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 22:02, 15 June 2018 (UTC)

::::Comes across a bit condescending considering m^2c^4=(mc^2)^2, not (mc)^4. The mass is the rest mass, which is always the same, considering it is measured at rest. It is a misnomer to call the total energy the mass. The physics you're describing is correct, I just take issue with the wording. I'm sorry if I didn't make myself clear enough. --[[Special:Contributions/162.158.146.70|162.158.146.70]] 22:29, 15 June 2018 (UTC)

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. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 19:03, 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.

: I don't think the relativistic mass is at all relevant. Presumably the gold would have to be brought to rest to be sold anyway, and I see nothing in the comic indicating that the gold would be sold based on this higher mass value. Also, these days physicists typically use "mass" to refer to what has historically been referred to as "rest mass", and have largely abandoned the idea that the mass of a particle increases with speed.

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