According to those in the know, the light from your headlights goes on forever, we just can’t see it. I had always wondered why it only shot out so far then stopped. Apparently, I had a thinking problem.
I also have questions about sound waves. Do they eventually dissipate? If not, then what is the driving force that keeps them going? I understand that when the sound comes from your car radio, then the driving force is your Chevy or Ford, or whatever it is you’re driving. In that instance, the sound would travel as long as your gas holds out.
Inside your house, of
course, the walls stop the sound waves. Although I’ve
never seen any damage to paint or wallpaper from sound waves. Nails and thumbtacks are a different story,
but we’ll get to that later.
I'm going to have to think about this.
