I'll try to explain.
You said you are going faster then time. Which is just absurd on it's face. Sci-fi doesn't enter into it.
It's like saying you can go faster then speed. Do you see? You can't have a speed that is faster then speed. It's just not a sane thing to say.
Just as your missile that fires missiles. The numbers you pull out of your sleeve are absurd as well as their effects, again sci-fi doesn't enter into it, this is basic logistics.
How do you store such things? How do you get such a payload into so small an area? How can you afford to throw such values of stuff away at any target?
Can't you see that such enormous numbers are meaningless on their face?
Against what could you possibly use such a thing? Not against a single ship, not even against a fleet of a few thousand ships, it would be a waste.
