tv snow is caused in part by cosmic rays?

Thats what they told us in school but i dont believe it. They said every pulse of static was a distant star or planet exploding.

Well I got a question about that....why does the static not increase when you hook an antenna up on an unused channel?? You can cut the antenna leads right off the tuner and no change.

With no signal the agc cranks the gain way up and noise from everything is amplified. I would blame the noisy carbon resistors before deep space. Maybe its a combination of everything.
