    • What are your thoughts so far on the cyclic model of the universe? Are you convinced by the arguments made in the lecture? Explain your answer.

    • If you’ve read my comments to the video, you know that I don’t think this to be a serious alternative. There are even more serious problems to solve than open questions with the inflation theory; to name the most important ones: Turning a crunch into a big bang, having a “decaying” dark energy to start contraction, contraction increases curvature, not the opposite.
      This model needs a lot of work to get even close to convincing me (and probably others).

    • Sounds highly plausible, but so at this point did inflation. The bottleneck bounce looks like the point where the theory might most easily go wrong.
