These were my questions:
Why is the word 'lisp' so incredibly hard to pronounce?
also..What happens beyond space? It has to end somewhere right?
And the wonderful Jake Hoffman and Lisa Malin graciously replied with these theories:

Hey Mia, well there are a lot of different theories. For example one of them is that the universe is expanding at a constant rate which would mean there has to be a edge of sorts. However this theory cant be proven due to the fact that viewing that far away would only show you the light and heat signatures given off billions of years ago... so to be honest nobody really knows and it cant be proven any time soon
Well, another viewpoint is that it isn't the *universe* that's expanding, just the matter contained in the universe. Space is infinite, but the amount of matter is limited, and has been expanding outwards since the Big Bang. Technically, there would be an "edge" of the expansion of matter, but that wouldn't be the edge of the universe because space would continue beyond that edge (there would just be nothing in it).
