If the Universe is expanding, what exists beyond the Universe ?
How can we determine the actual size of the Universe if there are parts of it we can never see or measure ?
The word UNIVERSE means EVERYTHING THERE IS. How can there be anything else ?
Is the Universe round or square ?
Yes (sort of).
I'm thinking flat.
