So as a pointless exercise i decided to work out the number of blocks (including air) in Era. So essentially, the map is a cylinder, having a set hight and a radius of 4000 blocks. So seeing as i can't find a button on my keyboard for pi (3.141592654), i'm gonna call it "P" and the radius will be called "R" and the height will be called "H". So the formula for the area of a cylinder is PR^2H. Which is just P x R x R x H. So that's P x 16,000,000 x 256. Which equals 4,096,000,000 x P. So the total number of blocks in Era is approximately 1.28679635 × 10^10. Which without standard form equals 12,867,963,500. So we can conclude here that there are nearly 13 billion blocks on our server. Put into perspective, that's 2 blocks for every person on earth. And assuming each block is 1m x 1m x 1m, it's 0.00000000117246944% of the volume of the earth. <------- THAT'S BIG.
