      Isn’t uranium that’s pure enough naturally to cause a reaction on its own really rare? I’m referring to the Chicago Pile experiment. It was so simple that it could have been theoretically built thousands of years ago which is crazy to think about.

        Not really. Every single shovel full of dirt has trace amounts. It’s just gathering enough into a pile. Like I said, nature did it on earth, before humans existed. It’s weapons grade uranium that’s really rare

          You can’t get a reaction when it’s that trace though. It needs to be unusually pure to be able to stack a bunch of raw ore and get a reaction.
