Has anyone read the Lost Fleet series? The books take a hybrid science/science fiction approach to deep space battles. The author depicts these battles to be like naval engagements but only last a fraction of a second as the ships flash past each other at a fraction of light speed. Though they employ mysterious inertia dampeners, the books include hard facts like the speed of light (if a ship suddenly appeared near Pluto, we would not see it for 4 hours or so), time dilation, ship formations, kinetic weapons (no need for mag cannons when you can drop a ton of metal on a planet traveling at 1/10 the speed of light), etc.
