ah but the tyranids are already here....

their travel time from one galaxy to another is in the millions of years (minimum), but the vanguard is already on the porch, so to speak, and the rest are right behind them on the lawn, and down the street, and around the block etc.

it will take time for them all to get in - i'd say another 10,000 years at the very least - but there are already untold trillions swarming over the front of our house.

theoretically the necrons could build an army of untold trillions if they had the time, which they don't, and if they had the materials, which they don't - they don't have time because the tyranids are here already, and they could have the materials if they had the galaxy to themselves, but every race is in a power struggle to appropriate as much materials/resources as possible, and as such those resources are spread out among the warring factions of 40k...leaving everyone ripe for munching :)
