So basically, there’s no sound in space? To take OP’s example, if I yelled, would I hear nothing?

Exactly. Astronauts will put their helmets together if they want to talk and can’t get a radio signal through (the helmets touching gives them something for the sound to travel through)

If you were wearing a space suit, you would hear yourself but others wouldn't. If you did not have a space suit, the air would rush out of your lungs the moment you opened your mouth. You might hear your voice up until the moment your lungs were empty (from inside your head), but no one else would.

Definitely no sound in space. If you watched an explosion in space, it would be silent until the moment the edge of the explosion reached you and then it would be chaos. Because explosions are (usually, depending on what exploded) made of gas that will carry sound.
