How To Make A Peruvian Carrot

Question of the day: Where does all the energy go? I got to thinking about one of Newton's laws, the one about every action having an equal and opposite reaction. I was thinking in terms of sound. Sound definitely has an energy...like when someone is driving a car with a deafening sound system. One that is loud enough to make my car shake. Sound makes the human eardrum vibrate and the brain interprets the vibrations into a particular sound. But where does the sound actually go? If I was sitting in a room talking to someone, my words would hit not only their ears, but also the walls, floor, ceiling etc. Where does it go from there? I would assume that the energy gets absorbed by the earth...but then what? Is the Earth harboring sound-related energy from the beginning of time? It can't just disappear, right? Maybe I don't know enough about physics to be writing about it and stuff. Maybe it dissipates into outerspace, but then what? And where does this infinite chain of energy come from? When I talk, I'm not really 'creating' energy, its more like I'm transfering energy from myself to outside myself. Like burning calories. So in the big picture, I'm really turning food into vibrations that resonate throughout the rest of time? That would be really freaky. Even on a spectacularly small scale, I could be affecting stuff all over the place just by honking my horn at some dipshit driver. I really gotta be more careful what I say now because you really can't take it back, in a literal sense. Don't even get me started on light related energy. That has to go somewhere too apparently. And it has to be 'created' somewhere. What if there was only a certain amount of energy in the universe and its just a matter of it showing up in different forms. Like it was all created at once and all you can do is manipulate a limited amount of pre-existent energy. That would probably answer my question because the energy would just get redistributed and end up back where it came from. I wonder if the Earth ever does something with the energy that we don't know about. Like put it into other things. Does my conversation eventually end up in a Peruvian carrot? We get energy from food, so the food must have gotten that energy from somewhere else. Cue the Twighlight Zone music.
