Idle thought: A "giga-ton" can, unconventionally, be taken as an English unit of force. A ton is 2000 pounds, after all, which would then give us a "gigaton" of force as 9x10^12 N.Slave Ship wrote:the laser cannons being mounted into the open skeletal frames required bracing and recoil-dissipation casings that would have withstood explosions measured in the giga-tonnage range. Anything less, and a single shot fired in battle would rip a destroyer or battle cruiser in two, a victim of its own lethal strength
The particularly creative will point also point out that 1x10^12 kg m/s is one gigaton meter per second.
Remarkable, just how creative you can get in trying to reconcile different sources.
