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).
