If the universe is filled with matter, and that matter causes space-time to bend, wouldn't the over-all structure be closed? Meaning, if I fly off in some random direction I would eventually "wrap around" the universe like a person moving across the surface of a sphere?
If so, is this compact structure inherent in the universe or just caused by matter? Is it just space dimensions that are compact or is time also compact?
