How can we determine whether or not we live in a cyclical universe? Are there any clues or patterns we can look towards?

    I breathe in and out, with my lungs expanding and contracting in a regular pattern. That’s a cycle.

    My heart beats, pumping blood through my body by expanding and contracting in a regular pattern. That’s a cycle.

    The Earth spins on its axis once every 24 hours. That’s a cycle.

    The Earth revolves around the Sun about once every 365 days. That’s a cycle.

    The Sun and the other stars in the galaxy are revolving around the center of the Milky Way. Those are cycles.

    All those manifestations of cycles on different levels suggest to me that the whole universe is currently in a particular phase of a cycle (let’s call it the expansion phase, since that’s what appears to be happening as galaxies get farther apart at an increasing rate).

    Although this is pure conjecture, I would guess that the universe will follow a pattern that will take it through different phases and eventually bring it back to its current phase, completing the cycle.
