This has somewhat of an 'inside joke' feel to it, to my non-technical, somewhat skeptical mind.
The problem is that they are completely serious.
Forward once gave a talk which I attended. He advocated making lots of anti-matter, and made the interesting claim that a pound of anti-iron would be relatively safe. "If you dropped it on the ground, it would just sizzle and melt," he said.
"Yeah, but the sizzling is releasing GAMMA RAYS," I reminded him, and the total energy in the pound of anti-iron might just destroy the earth. Melting it is bad because the surface area increases exponentially.
"Forward" thinking indeed.
