Radio waves are electromagnetic waves and as such travel at the speed of light. Waves emitted a century ago would be 100 hundred light years away. A light year is the distance light travels in one year. In one year light travels about 5.9 trillion miles. therefore the waves traveled about 590 trillion miles in a century.
Our environment can change our behavior in many aspects. Suppose you want to play golf with your friends, as you predicted it is going to be a sunny day but suddenly the environment changes and it converts into a rainy day then you have to change your plan.
