- Donīt EM transmissions fade at 1/r^3 ?
- Yeah but even with todays directed EM (cell phone, satellite comm.) a lot of it is reflected from structures and the earth itself and is rediated back out to space... Iīm sure that if we were say 34 light years away we could watch Armstrong land on the moon... and if we were 2 light years away listen to Aaron talking over his cell phone with his phone company complaining about yet another problem
