    Good presentation, it reminds me of Veritasium.
    If you could add a n animation that illustrates your point it would be easier to grasp what you are saying.

    Well explained, although I have a question. Why is there even a flatness problem? Isn't the anthropic principal enough? Looking forward to learn more from you

      Whether or not there is a flatness problem to begin with isn't something everybody agrees on - there are measures under which perfect flatness is natural and expected in a homogeneous universe, but to my knowledge this argument has not been broadly adopted within the standard lore/textbooks/courses. I don't think that the flatness we've observed is something that can be argued away through anthropic reasoning, either, unless you can think of compelling reasons that life couldn't exist in curved space.

      @@davidshlivko9594 does matter and energy distribution of the universe depend on curvature of universe?

      Not 100% sure what you mean by this - the curvature does affect how much energy density corresponds to a particular value of H (the Hubble constant) but not (directly) how it is distributed.
