Thanks... So it would seem that fifty tons of U is an even smaller package than I was thinking. Small in size... Even though you couldn’t carry it all in one pickup truck, it would still fit. Not that this means anything one way or the other. Just trying to visualize how much stuff we’re talking about.
Whut whut... Wait a second... It takes TEN tons of U to achieve critical mass... In a cannon-type tube weapon? Really?
