I've wondered that too. I remember thinking about that when I was a kid and it made me dizzy.
In a way, how could space not go on forever? It's the absence of matter. Matter in finite, we tend to think. But empty space? Of course now there's the concept of dark matter filling what we thought was empty outer space, but that's based on "missing mass/energy" calculations. Can't there be empty space beyond the reaches of the earliest photons? Why shouldn't there be nothingness beyond photoned-outer space?
