Fortunately, the madness you just thought about hasn't caught up with you, and you emerge from the nebula with little or no contact with anything formidable or threatening. However, as the universe is not a complete wasteland of atomic beings, you have attracted a large amount of atoms and other bits of matter and increased its mass dramatically. One might even call it an asteroid at this point, if there were any other neighbors around who could talk. Instead, the only things around them are simple particles of hydrogen and helium, and you can't hear them for more than a few minutes without laughing at their incredibly loud voices.
