When they say that the universe is constantly expanding, what does this exactly mean? I mean what can it be expanding into? I thought the word universe literally meant "everything", so what is on the other side of what it's expanding into? it cant be nothing can it? what exactly is nothingness? For example, if I was able to fly a spaceship to the end of the universe and go faster than it is expanding, what would I be flying into?
