Tell me about radio noise.
I was playing around with my tuner today, during what turned out to be a very boring day. In fact it was so boring, that I was listening to the radio noise, since the antenna was broken. And then, as it usually happens under these circumstances, I started thinking - what is it that I’m actually hearing? To be more specific - what is radio noise? I've tried looking it up on the net, but the closest I came to an answer is that its radio waves coming from either man made sources, or from natural phenomena. So does that mean that if I went to a very desolate place in the galaxy, and would hook my earphones to the tuner, I'd hear nothing? Or would there still be noise?
Pointless, I know. But still interesting.
