Tv channels and questions
How does that radio frequencies and oscillating waves and what not make sound and picture come from a television?
Are there a lot more channels that my television could pick up if I had a certain antenna?
How come I don't get channels from around the worlx?
How exactly is audio and video broadcasted?
What kind of equipment puts a video or sound out into the air?

Detonationology, an urban myth, the cosmic background noise level is well below other noise sources,
the following applies to simpler analogue video TVs;
unplug the antenna to see the noise level of the electronics
plug in antenna, tune to a 'quiet' channel to see
electronic + atmospheric + rfi noise + breakthrough of other channels
For a good start, have a look at the wikipedia article 'Television' https://en.wikipedia.org/wiki/Television
Before asking such questions it would be polite to do a little research of your own first, then ask specific questions,
what you asked for is so broad that no one would spend the time to fully answer, certainly not me.

My grandpa's TV used to have an antenna and would get a bunch of static when the microwave was cut on; then he got digital TV
