That would make it a reaction to a reaction, the timing being involved being far to short for a fleet of 900-meter warships to do much.
C) Because the ships were moving to fast for you to do anything but! You're saying that you can engage my ships, but my ships can't engage yours. You placed your fleet within range of a portion of my fleet.
I then placed the rest of my fleet in range of yours.
Lastly... we have ships that go faster than the speed of light, weapons that destroy planets in one shot, and can communicate instantaniously across the galaxy.
But we can't communicate within a single star system?
