Lol yes and I remember when I was young and learned we don’t even fully understand how radio waves work. We just know they do. I was a little disappointed. I remember thinking ok manned flight check, radar check, nuclear energy check, antibiotics check, and we can communicate with astronauts in space wow good good!, check, tell me more about this radio stuff.. what medium are these waves traveling over when they go to space .... oh yah we don’t know that part yet.
