0.004% is 0.00004, not 0.004, so the result is 50 billion galaxies.

- geuis 15y agoI don't think that's right. The author clearly states its 0.004% of the sky, not 0.00004%. Simply adding a percent sign doesn't change the number.
- iclelland 15y agoYes it does, actually: "per cent" means "per 100", so, divide by 100. 50% is 50/100, or 0.5 of the whole 0.004% of the sky is 0.004/100, or 0.00004 of the whole sky.
- tadfisher 15y agoYes, and 0.002 cents == $0.002.
- prophetjohn 15y agoIt's right. 0.004% == 0.00004 Just like 100% is equal to 1. If the image were 100% of the sky, you would divide by 1, not 100.
- ccollins 15y agoGeuis: .004 / 100 == .00004 / 1 And .004% = .00004
- stagas 15y ago100 / 0.004 = 25,000 So we'd need 25,000 images like that one, to fill the sky. 25,000 * 200,000 = 5,000,000,000 galaxies
