The problem with going down this road too far is that you start
other aspects of the game. If navigational shields and/or armour can
against megaton impacts due to rocks lying in the way of the ship, just
much energy is being generated by ship weapon systems? Or, for that
fighters? You start to get to the point where the weapons aren't Star
or Star Wars level of destructive, but something closer to Iain Banks'

And then you work out the size of the ships and take loses of power due
miniaturization, but still end up wondering why tanks -- in the same
universe -- aren't vapourizing anything in their path with energy
instead of using slug throwers.

I'm not disagreeing with anyone here, but as I like to caution, you can
use "real life physics" in FT so far before you run head first into a
logical wall. (See older discussions about missile momentum and throwing
rocks at ships at X% of the speed of light.)
