Is it possible, or in any way related, that a small but non-zero curvature could be responsible for the accelerated expansion of the universe? I don&#x27;t know, it&#x27;s hard to picture. But I&#x27;m thinking the idea that you can look at a sphere as a 2 dimensional space that curves and eventually wraps around such that things going opposite directions on its surface eventually can run into each other again.<p>That would probably be more easily measured though. I don&#x27;t know.
