[And a little bit more Drake’s Equation math before I head to bed…]

Well, okay, lets see what we have to work with here:

Using the alternate equation: N = N* * fp * ne * fl * fi * fc * L / Tg

– Assuming there are 1,000,000,000,000,000,000,000 stars in the universe
– And assuming that half of those stars have planets : 500,000,000,000,000,000,000
– And assuming there are two planets per system: 1,000,000,000,000,000,000,000
– And assuming there is life on all of these planets: 1,000,000,000,000,000,000,000
– And assuming 5% of them have intelligent life: 50,000,000,000,000,000,000
– And assuming 12% of those are harvestable: 6,000,000,000,000,000,000
– And assuming that the civilizations are active within a thousand year war cycle
– And assuming the age of the universe is 13,700,000,000
– 1,000/13,7000,000,000 = 0.00000000729927007299
– 6,000,000,000,000,000,000 * 0.00000000729927007299 = 43,795,620,438

Which means I need to figure out the scope of the war so I know how much of the universe it has covered, and thus how many civilizations it has run across.

*wanders off to dream up some maths* Woo! ^_^
