Radio doesn't, whereas TV waves do. AM/FM radio does not leave earth, but TV broadcasts do. Hence, the remark that the first an alien notices from our broadcasts, is a speech from Hitler.

Nope. If that was true, all mass from a supernova would reach us as the same speed. We can see the light, but we do not get the gold created in that nova.

All of them can behave like a wave or particle.
Again, no; only some "idiot" subatomic particles do. No proton ever pretends to be a wave?

Your definition is weak. How do you think Nasa communicated with Apollo astronauts? Would you categorize that as "TV"? As an example although an FM radio transmission tends to bounce on the atmosphere it can escape.

"mass" is not electromagnetic. A supernova emits all kinds of things that are not electromagnetic. Second space is not an absolute vacuum. As I said it is not possible, not anywhere, to have a absolute vacuum. Actual outer space is full of all sorts of stuff which impacts anything moving through it. Given a fixed, contained, uniform medium electromagnetic waves travel through that medium at a speed that reflects the medium. It will be slower than the absolute limit of the speed of light because the medium will have something in it.

A proton is not "light". A proton is matter. It has mass. It is a particle. A traveling proton (and other particles) can exhibit wave like behavior. Ocean waves are of course matter but they too exhibit wave like behavior.

You overestimate me; it ain't my idea. We got told that radio is subject to gravity, and TV waves would be different?

Methinks different kind of wave :D Don't get angry over my lack of knowledge.

Not sure if you're asking or telling, but radio waves are indeed light.
The difficult we do right away... ...the impossible takes slightly longer.
That will be why old British wireless sets had the "light programme" on their tuning dials ;-)

Gravity does impact them. But the impact of that is trivial in comparison to other things. TV/Radio get reflected by things like the earths magnetic field, water and other solids in the air, etc. Probably most significant factor is the ionosphere. You might want to google for the following and briefly read what it says. Briefly because it gets really deep really fast otherwise.

Yes and no. Ocean waves exhibit behavior (that very specific word) which has analogs for waves seen elsewhere.

About the only time I get angry is when I stub my toe on the coffee table. For social sites any negative emotion is usually boredom or confusion.

Radio does not leave earth, TV waves do. Don't take my word for it, it is just something they explained over 30 years ago.

While visually, water may have a wave, that is quite different from light.

Lego's here. Go to the toilet at night, step on it, fall down and curse like a sailor.

Yes they do. And they knew both that it did and the impacts of atmosphere long before 30 years ago. As I already noted - They used radio for the Apollo missions. Thus it did leave the atmosphere. Satellites have also directly used it. - Again read the links from the google that I suggested.

Best I can see you are confusing material with behavior. I can model the behavior of ocean waves on a computer.

Fortunately I learned about that early on so it only happened to me once. My real wake up call on that was when a friend ended up in the hospital with stiches because he stepped (technically jumped) on to a toy left out.

Now, not to pedantic, but they did not. Waves require a medium, there's no radio waves in a vacuum. They need to pinpoint voyager, which gives a hint on the sort of communication. Waves need no pinpointing.

You seem to think that there's something that can carry a wave in a vacuum. No radio signal ever left earth, our first signal into space was television.

I've been given a speech about them being 3d puzzles and it is my fault for not turning on the light. I got scolded for being an idiot :|
