No, not real Gold, but radioactive Gold. At a huge cost and a very, very small amount. And the Gold made won't remain Gold forever. So, yes, alchemy is still bullshit after all these years. Regular Gold is a very stable element. Now Carbon can be compressed hard enough to make diamonds. Very common these days, but a diamond is still Carbon. Don't try to cheat your fiancé because there is a slight difference between regular Earth grown diamonds and industry made diamonds.
Going back to my favorite element. Uranium - U238. It eventually ends up as Lead. Decay process:
. Thorium 234
. Protactinium 234
. Uranium 234
. Thorium 230
. Radium 226
. Radon 222
. Polonium 218
. Lead 214
. Bismuth 214
. Polonium 214
. Lead 210
. Bismuth 210
. Polonium 210
. Lead 206 (stable)
Plutonium is also is extracted from Uranium, so, all nuclear bombs in the planet come from Uranium. During WWII the U.S. made 3 Atomic bombs. The first was the test bomb in Trinity, New Mexico. That was a Plutonium bomb. The second was the Hiroshima bomb. That was a Uranium 235 bomb. The third was the Nagasaki bomb which was also made of Plutonium 239.
