Lasers don't work that way. See, the inverse-square law is about an emitted source diminishing because it broadcasts spherically - the surface area grows with r^2 because the surface is 2D. A laser doesn't work that way, nearly. Sure it diminishes, but the spread is astronomically (!) small. So for a distance of say 24000 miles you can 'beat' the law to a great degree. |
