  1. Well radio frequency (RF) moves at the speed of light. And another RF power falls at the square of the distance between the transmitter and receiver. So let's say there's a civilization 1000 light years from us. And they're transmitting. it would take 1000 years to reach us and be a very weak sign signal. And consider too radio has only been around for 100 years
